Hyper-IgE syndrome with recurrent infections--an autosomal dominant multisystem disorder. (1/17)

BACKGROUND: The hyper-IgE syndrome with recurrent infections is a rare immunodeficiency characterized by recurrent skin and pulmonary abscesses and extremely elevated levels of IgE in serum. Associated facial and skeletal features have been recognized, but their frequency is unknown, and the genetic basis of the hyper-IgE syndrome is poorly understood. METHODS: We studied 30 patients with the hyper-IgE syndrome and 70 of their relatives. We took histories, reviewed records, performed physical and dental examinations, took anthropometric measurements, and conducted laboratory studies. RESULTS: Nonimmunologic features of the hyper-IgE syndrome were present in all patients older than eight years. Seventy-two percent had the previously unrecognized feature of failure or delay of shedding of the primary teeth owing to lack of root resorption. Common findings among patients were recurrent fractures (in 57 percent of patients), hyperextensible joints (in 68 percent), and scoliosis (in 76 percent of patients 16 years of age or older). The classic triad of abscesses, pneumonia, and an elevated IgE level was identified in 77 percent of all patients and in 85 percent of those older than eight. In 6 of 23 adults (26 percent), IgE levels declined over time and came closer to or fell within the normal range. Autosomal dominant transmission of the hyper-IgE syndrome was found, but with variable expressivity. Of the 27 relatives at risk for inheriting the hyper-IgE syndrome, 10 were fully affected, 11 were unaffected, and 6 had combinations of mild immunologic, dental, and skeletal features of the hyper-IgE syndrome. CONCLUSIONS: The hyper-IgE syndrome is a multisystem disorder that affects the dentition, the skeleton, connective tissue, and the immune system. It is inherited as a single-locus autosomal dominant trait with variable expressivity.  (+info)

Immunolocalization of vacuolar-type H+-ATPase, cathepsin K, matrix metalloproteinase-9, and receptor activator of NFkappaB ligand in odontoclasts during physiological root resorption of human deciduous teeth. (2/17)

To investigate the cellular mechanisms of physiological root resorption in human deciduous teeth, the authors examined the immunocytochemical localization of vacuolar-type H+-ATPase, a lysosomal cysteine proteinase, cathepsin K, matrix metalloproteinase-9 (MMP-9), and receptor activator of NFKB ligand (RANKL) in odontoclasts. H+-ATPase, cathepsin K, and MMP-9 are the most important enzymes for decalcification of apatite crystals and degradation of type-I collagen. In addition, RANKL is one of the key regulatory molecules in osteoclast formation and functions. Odontoclasts developed extensive ruffled borders and clear zones apposed to the resorbing root dentine surfaces. On immunoelectron microscopy, the expression of vacuolar-type H+-ATPase was detected along the limiting membranes of pale vacuoles and the ruffled border membranes of odontoclasts. Cathepsin K in odontoclasts was localized within pale vacuoles, lysosomes, the extracellular canals of ruffled borders, and the underlying resorbing dentine surfaces. MMP-9 localization in odontoclasts was similar to those of cathepsin K. RANKL was detected in both mononuclear stromal cells and odontoclasts located on resorbing dentine surfaces. These results suggest that (1) odontoclasts are directly involved in decalcification of apatite crystals by active extrusion of proton ions mediated by H+-ATPase and (2) extracellular degradation of dentine type-I collagen by both cathepsin K and MMP-9, and (3) odontoclast differentiation and activity are regulated, at least in part, by RANKL, possibly produced by mononuclear stromal cells and odontoclasts themselves in the resorbing tissues. Thus, the cellular mechanisms of physiological root resorption appear to be quite similar to those of osteoclastic bone resorption.  (+info)

In vivo killing of Porphyromonas gingivalis by toluidine blue-mediated photosensitization in an animal model. (3/17)

Porphyromonas gingivalis is one of the major causative organisms of periodontitis and has been shown to be susceptible to toluidine blue-mediated photosensitization in vitro. The aims of the present study were to determine whether this technique could be used to kill the organism in the oral cavities of rats and whether this would result in a reduction in the alveolar bone loss characteristic of periodontitis. The maxillary molars of rats were inoculated with P. gingivalis and exposed to up to 48 J of 630-nm laser light in the presence of toluidine blue. The number of surviving bacteria was then determined, and the periodontal structures were examined for evidence of any damage. When toluidine blue was used together with laser light there was a significant reduction in the number of viable P. gingivalis organisms. No viable bacteria could be detected when 1 mg of toluidine blue per ml was used in conjunction with all light doses used. On histological examination, no adverse effect of photosensitization on the adjacent tissues was observed. In a further group of animals, after time was allowed for the disease to develop in controls, the rats were killed and the level of maxillary molar alveolar bone was assessed. The bone loss in the animals treated with light and toluidine blue was found to be significantly less than that in the control groups. The results of this study show that toluidine blue-mediated lethal photosensitization of P. gingivalis is possible in vivo and that this results in decreased bone loss. These findings suggest that photodynamic therapy may be useful as an alternative approach for the antimicrobial treatment of periodontitis.  (+info)

Cementum-like tissue deposition on the resorbed enamel surface of human deciduous teeth prior to shedding. (4/17)

Prior to the shedding of human deciduous teeth, odontoclastic resorption takes place at the pulpal surface of the coronal dentin, and this resorption occasionally extends coronally from the dentinoenamel junction into the enamel. After the end of resorption, however, the resorbed enamel surface is repaired by the deposition of a cementum-like tissue. Using this phenomenon as an observation model, in this study we examined the sequence of cellular and extracellular/matrix events involved in the enamel resorption repair by light and electron microscopy. As the odontoclast terminated its resorption activity, it detached from the resorbed enamel surface; thereafter, numerous mononuclear cells were observed along the resorbed enamel surface. Most of these mononuclear cells made close contact with the resorbed enamel surface, and coated pits or patches were observed on their plasma membrane facing this surface. Furthermore, they frequently contained thin needle- or plate-like enamel crystals in their cytoplasmic vacuoles as well as secondary lysozomes. Following the disappearance of these monononuclear cells, the resorbed enamel surface now displayed a thin coat of organic matrix. Ultrastructurally, this organic layer was composed of a reticular and/or granular organic matrix, but contained no collagen fibrils. Energy-dispersive X-ray microanalysis of this thin organic layer in undecalcified sections revealed small spectral peaks of Ca and P. Cementum-like tissue initially formed along this thin organic layer, increased in width, and appeared to undergo mineralization as time progressed. The results of our observations demonstrate that regardless of type of matrix of dental hard tissues, tooth repair may be coupled to tooth resorption, and suggest that mononuclear cells and an organic thin layer found on the previously resorbed enamel surface may play an important role in the repair process initiated after resorption of the enamel.  (+info)

Adenomatoid odontogenic tumor--a rare cause of jaw swelling. (5/17)

Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin, characterized histologically by the formation of ductlike structures with amyloid-like deposits. Histogenesis of AOT is still uncertain and it is often considered as a hamartomatous lesion rather than a true neoplasm. AOT has a benign behavior and conservative surgical enucleation or curettage is sufficient. We report a case of AOT in a 15-year-old female who presented with left-sided jaw swelling with tooth resorption. Histopathology revealed intraosseus follicular variant of AOT. A brief review of literature is also discussed.  (+info)

Analysis of the surface characteristics and mineralization status of feline teeth using scanning electron microscopy. (7/17)

External resorption of teeth by odontoclasts is a common condition of unknown origin affecting domestic cats. Odontoclastic resorptive lesions involve the enamel cementum junction (ECJ, cervix) and root surface, leading to extensive loss of enamel, dentine and cementum. This study was undertaken in order to determine whether features of the surface anatomy and mineralization of feline teeth could explain why odontoclastic resorptive lesions are so prevalent in this species. Backscattered electron scanning electron microscopy was used to study enamel, cementum and dentine in non-resorbed, undemineralized teeth from adult cats. Analysis of the ECJ revealed thin enamel and cementum and exposed dentine at this site. Furthermore, enamel mineralization decreased from the crown tip to the ECJ, and dentine mineralization was lowest at the ECJ and cervical root. Analysis of cementum revealed variations in the organization and composition of fibres between the cervical, mid- and apical root although no significant differences in mineralization of cementum were detected between different regions of the root. Reparative patches associated with resorption of cementum by odontoclasts and repair by cementoblasts were present on the root surface. In conclusion, results suggest that the ECJ and cervical dentine could be at a greater risk of destruction by odontoclasts compared with other regions of the tooth. The relationship of these features to the development and progression of resorption now requires further examination.  (+info)

Odontoclastic resorptive lesions in a dog. (8/17)

We found odontoclastic resorptive lesions on premolars and molars in a 4- year-old miniature dachshund. The teeth had been extracted because the dentin was resorbed. In some teeth, the roots had been replaced by hard tissue, and so we amputated the crowns and curetted roots and alveolar bone. Histopathological examination revealed that the dentin was resorbed by odontoclasts and was replaced with bony tissue. Ten months later we found resorptive lesions in other teeth, and we treated them along with the first treatment. At the time of writing, since this is the first report of a dog with the same lesion in other teeth after the first treatment, we hope to establish better treatment and prevention methods.  (+info)

Tooth Resorption is one of the more common oral diseases seen in cats. Tooth resorption, or cat cavities, is similar to cavities seen in humans. These cavities occur for many reasons, such as poor diet and age. Learn the symptoms and treatment so you can properly pursue proper remedies for your loving feline companion.
Do cats get cavities? They dont but they do face tooth resorption. Lets talk about what cat tooth resorption is, why it happens and if you can prevent it.
Tooth resorption is a process by which all or part of a tooth structure is lost due to activation of the bodys innate capacity to remove mineralized tissue, as mediated via cells such as osteoclasts. Types include external resorption and internal resorption. It can be due to trauma, infection, or hyperplasia. Internal resorption is an unusual condition where the dentin and pulpal walls begin to resorb centrally within the root canal. The first evidence of the lesion may be the appearance of a pink-hued area on the crown of the tooth; the hyperplastic, vascular pulp tissue filling in the resorbed areas. This condition is referred to as a pink tooth of Mummery, after the 19th century anatomist James Howard Mummery. The cause can sometimes be attributed to trauma to the tooth, but other times there is no known cause. If the condition is discovered before perforation of the crown or root has occurred, endodontic therapy (root canal therapy) may be carried out with the expectation of a fairly high ...
The only treatment for affected teeth at an advanced stage is extraction. Horses can manage quite well without their incisor teeth and should be able to eat a normal diet, including hay and even grazing. There are several ongoing studies looking into the causes and potential treatment options for this syndrome.. Molly Rice, DVM, and Travis Henry, DVM, DAVDC, who are currently studying the disease, say that many horses arent diagnosed until the end stages of the disease process, which is incredibly painful. If horses can be diagnosed and treated at an earlier stage, their quality of life can be improved greatly. In our practice we recommend radiographs of the incisors after the age of 15 to screen for resorptive lesions. This is a quick 10-minute process that can be performed during the horses routine dental examination. Over the past six years, we have treated over 200 cases similar to Peanuts. The extraction process is performed under standing sedation with local nerve blocks. The ...
Tooth resorption (TR) is one of the more common oral abnormalities seen in cats. In the past, tooth resorption was referred to as feline oral resorptive lesions, odontoclastic resorptions, cavities, caries, cervical neck lesions, external or internal root resorptions, and cervical line erosions. Although the premolars of the lower jaw are most commonly affected, lesions can be found on any tooth. Approximately half of cats older than three years of age will have at least one tooth affected ...
Rare reports of dysplasia in refractory cases and conversion to SCC.. Inflammatory Tooth Resorption (TR). Tooth resorption (TR) is a common disease of cats. The inflammatory form of the disease (see below) is seen at the cervical or neck area of the tooth and is thought to be associated with PD, although this is unproven.. At the present time, the aetiology of TR is not known.. Like periodontal disease (PD), TR may be asymptomatic, although symptoms such as dysphagia, ptyalism, face rubbing, jaw chattering, poor appetite, and weight loss may be seen.. Oral examination may show from little to abundant plaque and calculus covering the teeth, while hyperplastic gingiva may sometimes be seen extending onto the eroded tooth surface. TR can be confused with feline gingivitis/stomatitis, especially when there are retained roots in the mouth.. Prevalence of TR. Prevalence rates of 28-57% have been reported in the literature, and older cats are more likely to be affected, with the number of lesions ...

Tooth resorption is linked to tooth fractures and is a quite painful, progressive condition that occurs in dogs, and more commonly, cats.
Cats, with a global population estimated at 600 million, are considered the most popular pets worldwide, and are adapted to all the environments and to different lifestyles. We can distinguish different types of cat populations, according to their living, which raise different concerns on respect to neutering or contraception. Feline Leukemia Virus (FeLV) was the first retrovirus isolated in domestic cats, and the infection is associated with a wide variety of clinical syndromes, including feline acquired immunodeficiency syndrome (AIDS or fAIDS).. Inflammatory diseases of the oral cavity are common feline medical conditions and are associated with infectious agents such as Feline Immunodeficiency Virus (FIV), FeLV, herpesvirus (FHV-1) and calicivirus (FCV). The most common oral diseases in cats are gingivostomatitis, periodontal disease, tooth resorption and chronic periapical lesion by the canine tooth fracture. This book discusses the common diseases, clinical outcomes and developments in the ...
By Teresa Garden, DVM. Feline stomatitis is defined as inflammation of the mucous membranes of the mouth. It is a painful and frequent problem in cats. Treating stomatitis is frustrating for veterinarians as well as pet owners. It is believed the immune system of affected cats overreacts to plaque, causing severe inflammation in the mouth. Symptoms of stomatitis are decreased appetite, refusal to eat, chattering teeth, bad breath, salivation, bleeding from the mouth or gums, trouble swallowing, vomiting, retching, gagging, face rubbing, head shaking, nasal discharge, sneezing, fever, and depression. Your veterinarian may discover enlarged lymph nodes, tooth resorption, and ulcers in the mouth during a physical exam. Sometimes sedation is needed to do a thorough oral exam due to the painful nature of this disease.. There are other maladies that can lead to stomatitis besides a faulty immune system. This disease has been associated with viruses such as Calicivirus, Herpes virus, FIV, and Feline ...

An advantage of SEM compared with conventional histology is that it does not require demineralization of tissues, and allows the direct study of mineralized tissue surfaces. Previously, SEM has been used in studies of cat teeth to study enamel development (Boyde, 1964, 1969a,b), to measure the elemental composition of enamel, dentine and cementum (Colley et al. 2002), and to describe FORLs (Berger et al. 1996b; Gauthier et al. 2001; DeLaurier et al. 2005). In the present study, several features of teeth have been described which are consistent with previous descriptions of cat teeth made using other imaging methods. However, we have identified other structural features of cat teeth that have not been previously reported but may be significant for understanding FORLs.. Surface enamel was primarily smooth, lacking evidence of perikymata (incremental growth lines) and surface prisms, consistent with observations made in the cat and dog by Skobe et al. (1985). This prism-free layer was also observed ...
The Sapphire professional chairside treatment Before the teeth can be bleached, surface plaque, debris and calculus need to be removed by way of prophylaxis (teeth cleaning). If signs of gum inflammation and decay are present, these will need to be managed by the dentist before the Sapphire whitening gel is applied. Usually the dentist will photograph the teeth prior to applying the bleaching gel, so before-and-after comparisons can be made. The Sapphire Professional Chairside treatment contains 25% hydrogen peroxide. The whitening gel is applied to the teeth for either 30 minutes or 60 minutes, depending on severity of staining. Though results vary for each patient, Sapphire whitening gel lightens teeth by approximately 7 shades in 30 minutes and 12 shades in 60 minutes. Sapphire whitening is chemically activated, so no heat, lasers or lamps are required. ...
New crown sensitivity can vary from person-to-person, so this can be a difficult question to answer unless you go to the source that knows best-the dentist who placed your crown. And prior to going to your appointment, it is helpful if you have identified as many of the facts and/or triggers for any symptoms you have. For example, are your teeth sensitive to hot, cold, sweet, touch, pressure, or biting? It may be as simple as adjusting a minor high spot when you bite. Other questions to discuss with the dentist include the following. What was the extent of decay in the tooth prior to the crown? How close to the pulp (that contains the nerve) was the decay? Some sensitivity is normal after a crown as the tooth settles down; however, increasing sensitivity or pain after a week or more warrants a follow up visit to the dentist ...

Diagnosing gingival hyperplasia is important because there are several other forms of gingival enlargement that you must differentiate. For example, productive tumors of bone and cysts may cause the same appearance. Tooth resorption disease is a condition commonly seen in cats that also causes expansion of the gingival bone, resulting in a similar appearance. Gingival hyperplasia is by definition noninflammatory, but concurrent periodontal disease can cause inflammation to occur as a secondary process. Dental x-rays are often needed in order to help rule out potentially serious underlying medical conditions. A definitive diagnosis of gingival hyperplasia can be made only by biopsy and a microscopic examination.. There are two ways of treating gingival hyperplasia, medical and surgical. The simplest form of medical treatment is to stop any medications that are known to cause the disease. Unfortunately, in the majority of cases these medications are necessary to sustain a good quality of life in ...
During the consultation we will look carefully at your cats teeth and look for gingivitis, resorptive lesions, gum recession, periodontitis, broken teeth and the degree of calculus or tartar. For anything more than tartar and mild gingivitis we need a full dentistry. When there is just above the gum line calculus with minor gingivitis we can try removing the calculus without anesthesia, using water pressure instruments. If we are giving anesthesia for another reason anyway, we may do a light dental if not a full dental at the same time.. We encourage clients to be proactive at keeping on top of their pets teeth at an early age.. The easiest thing to do is socialize your cat to letting you into their mouth. You should teach him/her to let you lift up the lips to touch all the teeth. Be very gradual. Opening and looking down the mouth is not important for dental care, but it is a valuable tool to be able to do later on for a number of reasons, and in particular to give medication. If you ...

In other words, relating to the issue of Bassar BChalav, dentures are deemed not to be considered an actual utensil that requires kashering, but rather similar to genuine teeth themselves, sharing the same relevant halachos.. Several authorities maintain that the very same ruling would apply for Pesach, and rule that a thorough cleaning of the false teeth prior to Pesach would be sufficient[3].. Yet, other authorities, including the famed Maharsham[4], feel that one must be more stringent regarding Pesach, and rule that one must at least do an Iruy Roschin, or pouring boiling hot water over them, to be suitable for Pesach use. It must be noted, though, that Iruy is a lesser form of kashering and is usually not considered an acceptable process for utensils..

Traditional x-rays only allow dentists and surgeons to see your mouth in a two-dimensional world. However, we live in a three-dimensional world. Often, when planning more extensive implant therapy, or attempting to decide whether or not other surgical procedures may be necessary, the dentist or surgeon may make use of a three-dimensional cone-beam computed tomography (CBCT). CBCTs utilize about as much radiation as a standard panoramic x-ray (often used for evaluation of wisdom teeth prior to removal), yet allow for a richness of information that is unparalleled by standard x-rays.. In combination with CBCT data, a virtual surgery can then take place, allowing both the surgeon and the restoring dentist an optimal tool with which to communicate both of their planned procedures. Currently, it is possible to make surgical guides that replicate the exact virtual surgery on the computer, so that there are few to no surprises at the time of surgery as to where implants or bone grafts will be ...
Do you have Candida? There is a simple Candida Saliva Test you can do at home to find out. You may want to put a glass of water in the bathroom or on your night table the night before you wish to do the test just to remind yourself not to brush your teeth prior to spitting into the glass.
We present the Sr isotopic composition of enamel of the most ancient deciduous tooth ever discovered in Italy to assess human mobility in Middle Pleistocene. Reconstructing ancient mobility is crucial for understanding human strategy at exploiting temporally and spatially patchy resources, with most studies focusing on indirect evidences, ultimately affecting our interpretation on hominin territoriality and energetic costs invested by hominin groups. Here, we use the high spatial resolution and micro-destructivity options offered by the Laser Ablation Multi-Collector Inductively Coupled Plasma Mass Spectrometry technique, to determine the 87Sr/ 86Sr intra-tooth variability of a human deciduous incisor from the Middle Pleistocene layers of the Isernia La Pineta site (Italy). We compared these data with the Sr isotopic signature of local micro-mammals, the broadest home-range of the macro-mammals and with modern plant samples. Our study reveals that while macro-mammals have possibly migrated ...
Gingival Cord Applicator for Dental Crown Preparation - A gingival cord application tool is also disclosed which facilitates the separation of the gingiva from the tooth prior to the taking of the impression of the prepared tooth for purposes of crown fabrication. A truncated conical dental drill bit is also disclosed to facilitate the preparation of a tooth prior to installation of a dental crown. The drill bit includes a stem connected to an upper disc which, in turn, is connected to a downwardly extending sidewall having a conical configuration. The sidewall terminates at a lower edge and undersurfaces of the sidewall and upper disc are coated with abrasive material, such as diamond particles. The size of the drill bit is chosen for the particular tooth in need of repair and a single downward drilling operation is required to form a truncated conical configuration or crown receiving surface on the tooth. Finally, a measurement gauge is disclosed for measuring the tooth in need of repair and ...
The autosomal dominant form of HIS is characterized by recurrent pneumonia, sinopulmonary and fungal infections as compared to the AR form which is more commonly associated with skin, food allergies and Asthma. AD forms are strongly associated with history of musculoskeletal involvement and coarse facies which is absent in the AR form [4, 5].. Since tuberculosis and Acquired Immunodeficiency syndrome (HIV) is endemic in our country, our initial line of investigation was to rule out the above causes. The child also had recurrent atopic dermatitis and pneumonia, which further compelled us to investigate for common allergic cascade of diseases and treatment was initiated for the same. Since the patient did not have any relief in symptomatology and had repeated episodes of pneumonia and skin infections in the form of areolar abscess, we suspected immunodeficiency disorder, and on investigations, diagnosed the child with Hyper IgE syndrome in view of very high levels of Serum IgE (˃ 2000 ...

To understand the basis for the γδ T cell-dependent hyper-IgE syndrome that develops in the absence of Itk, we performed a detailed analysis γδ NKT cells in Itk−/− mice. Our previous studies demonstrated that this γδ T cell subset, expressing the Vγ1.1/Vδ6.3 (V6) TCR and the transcription factor PLZF, was highly expanded in Itk−/− mice and could secrete large amounts of type II cytokines, such as IL-4 and IL-13 (15). Using a combination of phenotypic, functional, and molecular analysis of V6 cells in the thymus, spleen, and liver, we have determined a number of important features of these cells. First, we show that the increased V6 population in Itk−/− mice is generally accounted for by cells expressing high levels of PLZF and constitutively expressing IL-4 mRNA. Second, based on a comparison with iNKT cells, we conclude that Itk−/− V6 cells do not fully mature and cannot transit to the stage associated with high level IFN-γ production. Third, we provide evidence that ...

Training students in the use of CEREC Blue light LED technology to fabricate chairside tooth colored restorations utilizing two innovative modes of fabricating the restorations Bigeneric Individual and Biogeneric Copy, enhances a students ability to apply this technology. At the New York University College of Dentistry students are trained in both modes to enable better decision making when designing these restorations. Many clinical situations may require that the final restoration of a tooth be an exact copy of a tooth such as when fabricating an indirect tooth colored restoration, a ceramic crown, or when duplicating adjacent teeth in the Esthetic zone. In the Biogeneric Copy mode, a digital picture of the unprepared tooth, and another digital impression of the prepared tooth is taken. The software transfers the occlusal aspects of the tooth in a preoperative condition and enhances the rest of the restoration. The final design of the restoration will be the same as the tooth prior to tooth ...
An osteoclast (from the Greek words for bone (ὀστέον), and broken (κλαστός)) is a type of bone cell that breaks down bone tissue. This function is critical in the maintenance, repair, and remodelling of bones of the vertebral skeleton. The osteoclast disassembles and digests the composite of hydrated protein and mineral at a molecular level by secreting acid and a collagenase, a process known as bone resorption. This process also helps regulate the level of blood calcium. An odontoclast (/odon·to·clast/; o-don´to-klast) is an osteoclast associated with absorption of the roots of deciduous teeth. An osteoclast is a large multinucleated cell and human osteoclasts on bone typically have five nuclei and are about 150-200 µm in diameter. When osteoclast-inducing cytokines are used to convert macrophages to osteoclasts, very large cells that may reach 100 µm in diameter occur. These may have dozens of nuclei, and typically express major osteoclast proteins but have significant ...
Sometimes a root canal treatment does not heal well the first time it is performed or the tooth becomes re-infected. This is typically due to complex root anatomy or a missed extra canal. In many cases, endodontic retreatment can be performed where the inside of each canal is cleaned or cleaned again for a second time. The prognosis will depend on the condition of the tooth prior to endodontic retreatment. We evaluate each and every tooth and develop a special treatment plan for your diagnosis. After endodontic retreatment is completed, a record of the procedure will be sent to your general dentist. You will then return to your general dentist for the final restoration or crown ...

Context: Neural mobilization is commonly used in sports, and previous studies have suggested that it has a positive impact on lower-limb flexibility and performance. However, studies exploring the effect of neural mobilization dosage are almost nonexistent. Objectives: This study aimed to assess whether 2 distinct dosages of neural gliding mobilization (4 and 8 sets of 10 repetitions) impact the flexibility and performance of both the mobilized and nonmobilized lower limb in basketball athletes differently. Design: Randomized, parallel, and single-blinded study. Setting: Amateur and professional basketball clubs. Participants: Fifty-two basketball athletes (40 men and 12 women), who were distributed into 2 groups; one received 40 (n = 28) and the other 80 repetitions (n = 24) of neural gliding mobilization. Intervention: Neural gliding mobilization applied to a single limb (the dominant limb). Main Outcome Measures: Knee extension angle for hamstring flexibility; hop tests and single-leg ...
Sixty-six guinea pigs with dental disease were presented to the University of Veterinary Medicine, Vienna, Austria, from 2006 to 2010. Almost all patients had a history of eating difficulties (95 per cent) and underwent clinical and oral examination as well as CT of the head. Findings on extra- and intraoral examination were asymmetric elongation (n=28) and symmetric bridging (n=24) of cheek teeth, obliquely worn incisors (n=17), palpable lower jaw swellings (n=13), exophthalmos (n=10) and incisor macrodontia (n=6). Eighty per cent of guinea pigs with exophthalmos showed ipsilateral periapical disease of the maxillary cheek teeth on CT. Ninety-two per cent of patients with palpable lower jaw swellings showed corresponding dental pathologies on CT. Periapical disease of incisors (n=11) and cheek teeth (n=32) were the most common findings on CT. All abnormally large incisors were found on oral examination and CT, but macrodontia of cheek teeth could only be visualised by CT. Deviation of the lower ...
Premolar tooth extraction. Close up of the blood-filled cavity left after the extraction of a decayed premolar tooth from a 67-year-old mans upper jaw. Dental caries is the decay and crumbling of the teeth. It is caused by the bacteria in plaque, a substance which covers the surface of unclean teeth. The bacteria break down sugar in the mouth, producing an acid which progressively destroys the teeth. In severe cases such as this, root canal surgery or tooth extraction is needed. For the tooth prior to extraction, see image C029/2193. - Stock Image C029/2194
You have surely already heard or tried the numerous health benefits offered by the habit of drinking a glass of water with lemon juice every morning on an empty stomach. Unfortunately, it also comes with one side-effect- as the acid in the lemon juice erodes the teeth enamel, and thus increases the sensitivity of the dentil and leads to dental issues. This risk cannot be avoided entirely, even when using a straw or brushing the teeth prior to drinking this drink. Yet, there is a solution- in the form of lemon essential oil!. According to Dr.Axe:. Lemons and lemon essential oil have been used in Ayurvedic medicine to treat a wide spectrum of health conditions for at least 1,000 years. Citrus plants are the main sources of benefit-rich essential oils because of their many uses in food and medicine. And lemon oil is one of the most popular citrus essential oils because of its versatility and powerful antioxidant properties.. The health benefits of lemon essential oil have been well established ...
Loss-of-function mutations in DOCK8 are linked to hyper-IgE syndrome. Patients typically present with recurrent sinopulmonary infections, severe cutaneous viral infections, food allergies and elevated serum IgE. Although patients may present with a spectrum of disease-related symptoms, molecular mechanisms explaining phenotypic variability in patients are poorly defined. Here we characterized a novel compound heterozygous mutation in DOCK8 in a patient diagnosed with primary combined immunodeficiency which was not typical of classical DOCK8 deficiency. In contrast to previously identified mutations in DOCK8 which result in complete loss of function, the newly identified single nucleotide insertion results in expression of a truncated DOCK8 protein. Functional evaluation of the truncated DOCK8 protein revealed its hypomorphic function. In addition we found somatic reversion of DOCK8 predominantly in T cells. The combination of somatic reversion and hypomorphic DOCK8 function explains the milder and
Root resorption is an unwanted effect of orthodontic tooth movement. Analysis of dentine proteins in gingival crevicular fluid (GCF) is a potentially safer method of quantifying root resorption compared with conventional radiographic methods. This study aimed to identify and quantify the dentine-specific matrix protein, dentine sialoprotein (DSP), released into GCF during physiological root resorption and orthodontic tooth movement. GCF was collected using micropipettes from 50 second primary molar sites undergoing physiological root resorption in 9- to 14-year olds [coronal group (Rc) with advanced resorption (n = 33) and apical group (Ra) with minimal resorption (n = 17)] and 20 subjects aged 8-14 years with erupted mandibular second premolars (control group). In addition, GCF was collected from 20 patients undergoing treatment with fixed appliances at two time points, immediately prior to orthodontic intervention (T0) and 12 weeks following commencement of fixed appliance therapy (T1). GCF ...

The patient is a 24-year-old male from Vandavasi in Tamil Nadu, India. He had developed a left lower jaw swelling around two years ago and visited a local hospital. Tests had been performed by an oral surgeon at the hospital. The patient had then been diagnosed with ameloblastoma of the left mandible. A left partial mandibulectomy had been performed followed by reconstruction with a rib graft and reconstruction plate. The patient had been left with a severe facial asymmetry with the right side of the mandible being longer than the left. This had depressed the patient to a degree that he refused to go outside. His career had suffered as a result and this alarmed his worried parents.. They had consulted with the oral surgeon again who realized the severity of the problem. The parents and the patient were informed that this could be addressed only at a specialist oral and maxillofacial surgery hospital. He had then referred them to our hospital for management of the patients facial ...
This is because the order of tooth eruption may be affected by factors such as the growth of teeth and periodontal tissue, but usually there will be no adverse consequences, and parents should not be too worried. According to data analysis of the American Academy of Pediatrics, babies usually germinate their first deciduous teeth within 6-12 months, but due to individual differences, babies first teeth before 12 months are normal teething cycles. If the baby has not started to produce the first deciduous teeth after 18 months of age, it is normal to call the late deciduous teeth. Under normal circumstances, the baby will germinate the first baby teeth in about six months. At about two and a half years old, the deciduous teeth are almost all out. But this is only a general rule, because each baby is different, there will be individual differences in teething time. In addition to the timing of teething, the order of teething is also regular. Most babies will grow their deciduous teeth one by one ...

  • Internal resorption defines the loss of tooth structure from within the root canal/s of a tooth. (
  • Chronic pulpal inflammation is thought to be a cause of internal resorption. (
  • External resorption is often easier to see than internal resorption because it commonly occurs on the outer surface of a tooth. (
  • Internal resorption affects the inside of a tooth. (
  • Many people are unaware they have internal resorption because it affects only the tissues inside of a tooth. (
  • Instead, a dentist or dental hygienist most often detect internal resorption on X-rays taken during a routine dental exam. (
  • On an X-ray, a tooth with internal resorption will show dark spots where internal tissue is missing. (
  • External resorption is much more common than internal resorption. (
  • Most often internal resorption is caused by a physical injury to a tooth or swelling of the inside of a tooth caused by an untreated cavity . (
  • With internal resorption, a dentist or dental hygienist may notice dark spots inside your teeth that are visible in X-rays of your mouth. (
  • Types of tooth resorption include internal resorption and external resorption. (
  • There are two types of internal resorption: root canal (internal) replacement resorption and internal inflammatory resorption. (
  • Pathological resorption may start from the root surface ( external resorption ) or from the pulpal surface ( internal resorption ). (
  • It can occur on the external or internal tooth surface (external or internal resorption). (
  • Multiple internal resorption in permanent teeth associated with hyperparathyroidism. (
  • Internal resorption has been described as a resorptive defect of internal aspect of tooth . (
  • Though mostly idiopathic in origin, trauma , caries and restorative procedures have also been suggested to be contributing factors of internal resorption of pulp. (
  • Most of the internal resorption cases were found on isolated individual tooth . (
  • Though many cases related to dental manifestations of chronic renal disease and internal resorption of permanent teeth have been documented in literature , there is no evidence on association of hyperparathyroidism with multiple internal resorptions of teeth . (
  • as well as uncommon internal resorption in many of their teeth with any etiologic factor. (
  • According to oral manifestations of systemic sclerosis, It seems that internal resorption can be associated to their systemic disease. (
  • LESSONS The dental pulp tissues may be involved in the initiation or development of internal resorption. (
  • Tooth-root resorption, also known as shortening or erosion,(TRR) is one of the adverse outcomes of dental trauma, orthodontic tooth movement and dental replantation/transplantation. (
  • Root resorption is an unwanted effect of orthodontic tooth movement. (
  • This study aimed to identify and quantify the dentine-specific matrix protein, dentine sialoprotein (DSP), released into GCF during physiological root resorption and orthodontic tooth movement. (
  • Odontoclast activity can be stimulated by inflammation, pressure from adjacent structures, orthodontic tooth movement, as a result of normal processes such as exfoliation of deciduous teeth, or in the absence of these processes (idiopathic). (
  • However, orthodontic tooth movement (OTM) heightens the risk and severity of root resorption, which is irreversible, as well as increasing risks of gingival change or color alteration. (
  • This review searched the current knowledge of the mechanical and biological aspects of root resorption in orthodontic tooth movement. (
  • External root resorption, orthodontic tooth movement, risk factors. (
  • Orthodontic tooth movement is based on force-induced periodontal ligament and alveolar bone remodeling. (
  • The purpose of this study was to compare the effect of three common NSAIDs drugs including Acetaminophen, Aspirin and Ibuprofen on the rate of orthodontic tooth movement and root resorption in rabbits. (
  • The animals were sacrificed after 1 month and orthodontic tooth movement of 1st molar was measured with special gauges with 0.05mm accuracy. (
  • Effects of mesenchymal stem cell transfer on orthodontically induced root resorption and orthodontic tooth movement during orthodontic arch expansion protocols: an experimental study in rats. (
  • Tooth resorption goes by many other names, including cavities, neck lesions and feline odontoclastic resorption lesions (FORLs). (
  • Resorptive lesions are usually found on the tooth at or around the gum line. (
  • Those ailments include gingivitis, plaque buildup, and what's referred to as "tooth resorption" or lesions - also known as cat or kitty cavities - which are, yep, you guessed it - the feline equivalent to human cavities. (
  • These lesions were originally called feline "neck lesions", "cervical line lesions" and cat "cavities" because the lesions were typically observed in the "neck" region of the tooth or cervical area (in the region of the sulcus). (
  • It has been determined the lesions typically begin in the cervical area of the teeth and the resorption may extend into the root, the crown or in both directions. (
  • Feline odontoclastic resorptive lesion (FORL) is a term that has had widespread use, however, feline tooth resorption is currently considered the best term to describe these lesions. (
  • It has been our experience that cats who have had tooth resorption diagnosed, will very likely develop additional lesions in the future. (
  • All types of external resorption are irregular in outline and extensive lesions often spare a thin layer of dentine around the pulp so that the pulp can remain vital until a late stage, even if the defect communicates with a gum pocket. (
  • Clinical Signs of Oral or Dental … In the past, tooth resorption was referred to as feline oral resorptive lesions, feline odontoclastic resorptions, cavities, caries, cervical neck lesions, external or internal root resorptions, and cervical line erosions. (
  • These lesions have previously been referred to as feline odontoclastic resorptive lesions (FORLs), neck lesions, cervical lesions, cervical line lesions, feline caries, dental resorptive lesions, external odontoclastic resorptions, cervical root resorptions, feline odontolysis and most likely many more. (
  • By whatever name these lesions are referred to, they are not a new phenomenon, with tooth resorption having been detected in feline skeletons many hundreds of years old. (
  • Some cats will have a single tooth affected by tooth resorption, others will develop multiple lesions over their lifetime. (
  • Tooth resorption can be a very painful condition for cats with these lesions. (
  • Extractions is the only effective treatment for tooth resorption once diagnosed as the lesions are progressive. (
  • In many but not all lesions, concomitant osteoblast and cementoblastic activity replaces the lost tooth with bone or cementum. (
  • Small lesions on the enamel of the tooth crown usually begin somewhere on the root surface but can progress coronally and then appear at the gingival margin as inflamed granulation tissue filling a defect. (
  • Stage 3 lesions affect the pulp cavity, but most of the tooth retains its integrity. (
  • Stage 4 lesions have significant crown or root damage, with most of the tooth having lost its integrity. (
  • Tooth resorption lesions exposed to the oral cavity may cause discomfort. (
  • Lesions limited to root surfaces only are unlikely to cause discomfort or other clinical signs unless they are associated with resorption of bone adjacent to the tooth resorption (eg, resorption caused by painful inflammation from periodontal or endodontic disease). (
  • In any case, further investigation is needed to determine resorption detection thresholds in various two-dimensional and three-dimensional imaging techniques, as well as to determine therapeutic thresholds and criteria for strategic tooth extraction based on radiographic manifest and not manageable resorption lesions. (
  • Tooth resorption is also referred to as cervical line lesions, resorptive lesions, or feline odontoclastic resorptive lesions (FORLs). (
  • Tooth resorption is graded based on the extent and location of the lesions. (
  • Extraction of these lesions can be difficult, because affected teeth are fragile and often fracture during extraction. (
  • Along with white-spot lesions, root resorption is the major iatrogenic consequence of orthodontic treatment. (
  • However, once the tooth is exposed to the oral cavity after eruption, it becomes highly vulnerable to the development of carious lesions. (
  • the prevalence of the lesions has been reported to be 3 - 6% in children and adolescents and in 0.5 - 2% of teeth [ 1 , 2 ]. (
  • Detection of the lesion has been known to be difficult at the pre-eruptive stage of PEIR because an unerupted tooth is rarely infected with cariogenic microorganisms and, thus, such lesions are asymptomatic. (
  • Beginning spots or lesions are usually small enough to surgically remove the tissue cells causing the damage and then filled with a tooth-colored filling material. (
  • However, pathological root resorption, mainly the inflammatory one, is a consequence and/or complication of several clinical conditions, such as dental trauma and periapical inflammatory lesions from dental caries, thus becoming a common cause of tooth loss. (
  • This study was undertaken in order to determine whether features of the surface anatomy and mineralization of feline teeth could explain why odontoclastic resorptive lesions are so prevalent in this species. (
  • Clinical and histological studies have identified lesions as external, subgingival defects that initiate on the surface of the tooth root and progress to involve dentine. (
  • Tooth resorption (TR) lesions appear tooth-coloured, but may appear red when inflamed gum tissue moves up onto the tooth, and " Band-Aids " or covers tooth defects above the gumline on the tooth. (
  • In cats , TR lesions are most commonly seen at or above the gumline in teeth other than the canines/fang teeth (these teeth usually have lesions at or below the gumline only detectable on X-ray). (
  • Tooth Resorption (TR) is the only American Veterinary Dental College Nomenclature Committee accepted term for these lesions. (
  • Research continues into the exact cause of resorptive lesions, though overactive bone resorption cells (odontoclasts) are a consistent feature of TR changes. (
  • During this exam, the lesions are probed and the stage of the resorption is determined by the depth of the probe. (
  • Particularly in regards to external inflammatory apical root resorption, several studies have shown a positive correlation between this disease, pulp necrosis, and the presence of periradicular lesions (Campos, et al. (
  • Radiographic analysis showed communication of the temporary restorative material with the pulp chamber, periradicular lesions in both roots, and severe inflammatory apical root resorption in the distal root (Figure 1A). (
  • Figures 1A-1C: A. Initial periapical radiograph of tooth No. 36, showing periapical lesions in both roots, and severe apical root resorption in the distal root (circle). (
  • [9] Prolonged dental plaque accumulation on the tooth surface can lead to enamel demineralisation and formation of white spot lesions which appear as an opaque milk-coloured lesion. (
  • Ankylosis and disrupted or altered root development are frequent complications associated with intrusive luxation and tooth avulsion lesions. (
  • Osteoclasts are active during bone regulation, there is constant equilibrium of bone resorption and deposition. (
  • External resorption is often caused by injuries to the mouth and teeth that cause swelling and loss of bone and tissue on and around a tooth. (
  • The aim of this case report was to present a child with CAH, premature exfoliation of primary teeth and accelerated eruption of his permanent teeth related to bone resorption. (
  • Tooth mobility was noticed in the permanent teeth as soon as they erupted, along with bone destruction. (
  • Increased bone resorption in patients with CAH has been noted in the past and has been related to alterations in receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG). (
  • 7 Also, bone resorption has been related with loss of teeth in patients with osteolytic diseases. (
  • Recently, bone resorption has been found to be correlated with accelerated eruption of teeth in mice. (
  • However, susceptibility to periodontal disease and bone resorption can be the cause for primary exfoliation of primary teeth and accelerated eruption of its successors. (
  • However, the literature have pointed out that torque tooth movement, especially when the root apices are torques against cortical plates of bone produces the most dramatic type of tooth root resorption with poor prognosis. (
  • The natural shedding of baby teeth follows the progressive resorption of the roots by cells resembling osteoclasts (Cells that functions in the breakdown and resorption of bone tissue). (
  • This physiological resorption may be an inherent developmental process or it may be related to pressure from the permanent successor against the overlying bone or tooth . (
  • Microscopic areas of superficial (surface) resorption of the roots of permanent teeth are common but are transient and are repaired by the apposition of cementum or of a bone-like tissue. (
  • Resorption of tooth is the process of removal of dental hard tissues by bone cells called osteoclasts. (

  • There are two distinct histological types of root surface resorption: Type I (inflammatory) and Type II (replacement by bone). (
  • Type II tooth resorptions results in the tooth being replaced by bone and the periodontal ligament anchoring the tooth and bone is lost. (
  • If the abscessed tooth has extensive bone loss around its socket, or if there is significant damage to the crown of the tooth, your veterinarian may recommend extraction as the best treatment. (
  • Necrosis of periodontal ligament on the pressure side with formation of a cell-free hyaline zone followed osteoclast resorption of the neighbouring alveolar bone and bone apposition by osteoblasts on the tension side are the well-described typical histological characteristics of these processes. (

  • The tooth and bone implants were harvested, sutured together, reimplanted, and grown in the omenta for an additional 8 weeks. (
  • Histological and immunohistochemical analyses of the excised hybrid tooth-bone constructs revealed the presence of tooth tissues, including primary and reparative dentin and enamel in the tooth portion of hybrid tooth-bone implants, and osteocalcin and bone sialoprotein-positive bone in the bone portion of hybrid tooth-bone constructs. (
  • Collagen type III-positive connective tissue resembling periodontal ligament and tooth root structures were present at the interface of bioengineered tooth and bone tissues. (

  • Also, teeth affected by cat cavities are already very fragile, and easily fracture or break during the cleaning or removal process anyway. (
  • Nearly everyone knows that cavities are a threat to the health of teeth, but you might be surprised to learn that there's another way teeth can be broken down. (
  • While cavities typically form due to poor oral hygiene and a buildup of plaque and tartar, tooth resorption occurs from the inside out. (
  • While cavities start on the outside of the tooth and erode away at the tooth's surfaces, tooth resorption begins on the inside of the tooth, which means it may not be immediately visible to the eye, even during a dental examination. (

  • Type 2 tooth resorption: Treatment with crown amputation with intentional root retention can done if there is advanced root resorption, no evidence of periapical periodontitis or periodontal disease, or stomatitis. (
  • Inflammation from periodontitis is known to cause external resorption and is most likely responsible for tooth resorption in areas of periodontal disease. (
  • A tooth root abscess may also develop in association with periodontal disease, an infection of the tissues surrounding the tooth. (
  • Various factors have been suggested to underlie the disease, such as periodontal disease, dietary factors, mechanical stress, developmental tooth defects, breed and viral disease, although none of these factors has been definitively proven to be the direct cause of resorption (see review by Reiter & Mendoza, 2002 ). (
  • Signs of periodontal disease include red swollen gums, receding or overgrown gumline, supra-erupted ('snaggle') teeth, purulent discharge (pus) and bad breath (halitosis). (
  • Gum (periodontal) disease is infection and inflammation of the tissue surrounding the teeth. (
  • If periodontal disease goes untreated, teeth can be lost due to the loss of their supporting tissues. (
  • Complications associated with tooth decay and periodontal disease . (
  • In a condition known as a tooth resorption -formerly referred to as feline odontoclastic resorptive lesion (FORL) or cervical line lesion-the dentin in a single tooth (or several simultaneously) erodes and eventually becomes irreparably destroyed. (
  • I recommend that a cat's teeth be visually examined by a veterinarian annually," she advises, "and that they be x-rayed if a resorptive lesion is suspected. (
  • Eventually, the affected teeth may become fragile due to the inflammatory resorptive process. (
  • TR has also been called "feline odontoclastic resorption lesion", neck lesion, cervical neck lesion, cervical line erosion, feline subgingival resorptive lesion, feline caries, or feline cavity. (
  • Most studies agree that on the average 50% of cats have at least one tooth resorptive lesion. (
  • Tooth resorption from any cause occurs through the action of odontoclasts that remove tooth structure, creating a resorptive lacuna. (
  • Unfortunately, once a cat has had resorptive disease, it's very common for other teeth to be affected. (
  • Good dental hygiene, including brushing and feeding a species-appropriate raw or wet diet (contrary to what many cat parents still believe, dry food does not clean teeth ) will certainly contribute to the overall health of your cat, even if they may not prevent resorptive disease. (
  • Pulp necrosis, trauma, periodontal treatment, orthodontics and tooth whitening are the most common stimulants of inflammatory resorption. (
  • The pulp must be vital below the area of resorption to provide osteoclasts with nutrients. (
  • If the pulp becomes totally necrosed the resorption will cease unless lateral canals are present to supply osteoclasts with nutrients. (
  • Inside is a very soft substance: the pulp of the tooth. (
  • X-rays showed nothing but soft tissue, a tooth cap resting precariously at the gum line, the base of the tooth exposing all that soft pulp. (
  • Tooth resorption is a common sequela following injuries to or irritation of the periodontal ligament and/or tooth pulp. (
  • External inflammatory root resorption can be further categoriezed into cervical resorption with or without a vital pulp (invasive cervical root resorption) and external apical root resorption. (
  • A non-vital pulp may also trigger external resorption of the root towards the crown by producing toxic products which diffuse outwards to the periodontal ligament along the dentinal tubules. (
  • Inflammatory resorption typically involves the apical portion of the root, as a result of periapical inflammation following pulp death or trauma. (
  • The sensitive pulp is surrounded by tubules, called dentin, which also contain nerve fibers and make up the majority of the tooth. (
  • Saving the pulp is vital to keep your tooth alive, which is a priority for dentists. (
  • Your dentist will gain access to the root canal through the top of your tooth and use an instrument to clean out all of the pulp material and tissue inside the canal. (
  • A root canal won't stop your tooth from producing new pulp. (
  • Your dentist will try to keep your tooth alive and healthy, but sometimes the damage from resorption leaves the pulp too badly damaged or entirely dead. (
  • The treatment strategies for PEIR include (1) tooth extraction (when restoration is not feasible), (2) restoration after surgical exposure, and (3) restoration (including pulp treatment) after a follow-up examination until tooth eruption [ 8 ]. (
  • When either or both of the carnassial teeth are fractured exposing the underlying pulp a severe painful infection can develop. (
  • Endodontic treatment of a tooth with pulp necrosis and severe inflammatory external apical root resorption in a single session: Is it possible? (

  • Identify the steps that lead to the success of pulp necrosis and severe inflammatory apical root resorption in a single session after a 6-month follow-up. (
  • However, to date, no conclusive scientific evidence has been found on required use of an intracanal medication in cases of pulp necrosis, periradicular lesion, and severe associated inflammatory apical root resorption. (
  • Teeth that underwent pulp treatment presented with external resorption. (
  • Trauma to the periodontal ligament might play a major role in external resorption, whereas internal tooth resorption may be caused as a result of injury to the residual pulp tissue . (
  • The objective of reimplanting teeth with immature root development is to facilitate the possible revascularization of the pulp chamber. (
  • In primary molars without permanent germs, odontoclasts and immune cells were present mainly in the apical pulp at the start of root resorption, whereas in control teeth receptor activator of nuclear factor-jB ligand (RANKL)-positive cells were found mainly in the region of the periodontal ligament. (
  • These results suggest that the dental pulp of primary molars, as well as immune cells, may play an important role in root resorption in primary molars without permanent tooth germs. (
  • Endodontic disease occurs when the dental pulp (odontoblasts, fibroblasts, undifferentiated mesenchymal cells, blood vessels, and nerves in the center of the tooth) becomes infected and/or inflamed. (
  • A tooth with direct exposure of the pulp at a fracture site requires endodontic treatment or extraction. (
  • An inflamed or dead pulp releases inflammatory mediators into the periradicular tissues (through furcation canals into the periodontal ligament at the furcation of a multirooted tooth, through lateral canals into the periodontal ligament at the mid-root level, and through apical foramina into the periapical tissues). (
  • A discolored tooth (pinkish, purple, or gray) is evidence of previous trauma and hemorrhage from the pulp into the dentinal tubules. (
  • The most obvious indication of endodontic disease is a fractured tooth with exposure of the pulp chamber. (
  • Throughout life, the pulp produces dentin on the inside surface of the pulp cavity, resulting in a constantly decreasing cross-sectional width of the pulp chamber in the crown and root canal in the root of the tooth. (
  • A necrotic pulp discontinues its normal dentin production, and thus it falls behind that of a normally maturing tooth adjacent to it or on the contralateral side. (
  • If there is generalized pulpitis, the effect can be an apparent accelerated aging of the entire tooth with an abnormally narrow root canal space and pulp chamber. (
  • Generally, when evaluating a tooth with endodontic and/or periapical disease, the focus should be on structural defects at its crown and root apex, the width of its pulp cavity, and the appearance of the periapical tissues. (
  • Teeth with irreversible pulpitis or pulp necrosis require either endodontic treatment (root canal therapy) or extraction. (
  • Except in very young animals, one of these options is indicated for every tooth in which a fracture has exposed the pulp chamber. (
  • If veterinary examination reveals the presence of tooth resorption, Dr. Rawlinson points out, the only effective treatment will entail extraction of any affected teeth. (
  • Removal can be a dicey process, too, as these teeth are often so compromised that they have become brittle and may shatter during extraction. (
  • The treatment protocol of teeth diagnosed with severe OIIRR or other forms of TRR always involves root canal treatment or extraction of these teeth in severe cases and prosthetic replacement. (
  • Once a cat cavity is confirmed, your vet will want to move forward with a thorough, deep cleaning and full extraction of the affected tooth or teeth. (
  • The only treatment for affected teeth at an advanced stage is extraction. (
  • and if not - won't the tooth get worse and then the subsequent extraction involve cutting into my jaw? (
  • Teeth affected by this condition have a tendency to splinter into fragments during extraction, which can lead to complications. (
  • In the event of tooth resorption, extraction is the only solution. (
  • Extraction is the only treatment for tooth resorption. (
  • Incisor apical resorption was significantly greater in the extraction sample (ca 0.5 mm). (
  • One option is a root canal treatment, which usually saves the tooth, and the other option is extraction. (
  • Unfortunately, tooth extraction is often the only realistic treatment option at that advanced stage. (
  • Protein biomarkers of external root resorption: A new protein extraction protocol. (
  • After tooth extraction, alveolar ridge loss due to resorption is almost inevitable. (
  • Many studies have indicated that applying socket-filling biomaterials after extraction can effectively reduce the resorption rate of the alveolar ridge. (
  • In conclusion, the HA/β-TCP + collagen graft demonstrated adequate safety and efficacy in dental socket preservation following tooth extraction. (
  • The teeth extraction was given to one patient . (
  • In some cases, if the remaining teeth are infected or weak, we will recommend a tooth extraction first. (
  • Common justifications given for the extraction of wisdom teeth. (
  • External resorption may be caused by inflammation and by pressure or mechanical stimulation or be of unknown (idiopathic) cause. (
  • Many cases of so-called inflammatory resorption, both internal and external, are not associated with significant inflammation clinically or histologically and are perhaps better regarded as idiopathic. (
  • This idiopathic tooth resorption occurs sporadically in many species (including people), but it is most frequently seen in domestic cats. (
  • However, the etiology of idiopathic tooth resorption affecting multiple (possibly all) teeth in cats has not yet been proved. (

  • Idiopathic osteosclerosis is a condition which may be found around the roots of a tooth . (
  • Condensing osteitis may resemble idiopathic osteosclerosis, however, associated teeth are always nonvital in condensing osteitis. (
  • The key cells involved in resorption are of the clastic type, which include osteoblasts and odontoclasts. (
  • In short, odontoclasts, normal cells located within the periodontal ligament, are for some reason activated and begin a pathological resorption of the root surface. (
  • The dentin (makes up the bulk of the tooth structure) is eroded by cells called odontoclasts and eventually becomes irreparably destroyed. (
  • Resorption of tooth structure occurs through the action of odontoclasts-cells virtually identical to osteoclasts. (
  • The odontoclasts cells are responsible for resorption of dental tissues, and they are influenced by several stimuli and molecular signals derived from cytokines, neuropeptides, hormones and degradation products released when tissue is injured. (
  • However, so far it is not clear what leads to the differentiation of the precursor cells of odontoclasts, what gives them the signal to start the resorption in a specific place and time (especially in primary teeth) and why they are activated in some pathological conditions, but not in others. (
  • External resorption of teeth by odontoclasts is a common condition of unknown origin affecting domestic cats. (
  • Reparative patches associated with resorption of cementum by odontoclasts and repair by cementoblasts were present on the root surface. (
  • In conclusion, results suggest that the ECJ and cervical dentine could be at a greater risk of destruction by odontoclasts compared with other regions of the tooth. (
  • A cat may lose just one tooth in its lifetime because of this problem," she points out, "although it can have a little bit of resorption on other roots that may not require treatment. (
  • It can affect any part of the outside of the tooth, from the roots to the cementum on the outside. (
  • Resorption affecting the roots of a tooth can be seen in X-rays as a shortening of the lengths of the roots and a flattening of the root tips. (
  • As the disease progresses, the roots of the incisor teeth begin to resorb, causing the roots to lose structural integrity. (
  • Some horses experience hypercementosis-the excessive buildup of cementum (calcified tissue) around the roots of the incisor teeth. (
  • Right: Advanced EOTRH in a 24-year-old horse with hypercementosis causing a bulbous appearance around the roots of affected teeth. (
  • The challenge has been to move teeth and their roots effectively while minimizing iatrogenic damage such as root resorption and gingival inflammation. (
  • The roots of the tooth are reabsorbed into the body, allowing the tooth to loosen and fall out of your gums. (
  • This is why baby teeth lack the visible roots that extracted teeth have. (
  • As a new permanent tooth develops, the roots undergo a process of breakdown and growth. (
  • In 11 patients abnormal resorption occurred only in the roots (group I). In 3 patients resorption occurred in the roots as well as in the crown (group II). (
  • The study showed an abnormal resorption pattern of roots and crowns of primary teeth before the permanent successor had barely begun root formation. (
  • This happens because these tooth roots lie just below the eye, and when they become abscessed the infection quickly spreads to the surrounding tissues. (
  • Our findings suggest that the homozygous recessive H2665L missense sequence variant impairs the normal morphology of the teeth roots via loss of cementum synthesis, and is also associated with early onset, recessive, Wagner syndrome, thus expanding both the phenotype mutation scenario and the inheritance mode of VCAN mutations. (
  • The pathophysiology of stimulation of osteoclasts in the process of inflammatory resorption is unknown. (
  • If the insult is transient, resorption will stop and healing will occur, this is known as transient inflammatory resorption. (
  • It can be further divided in the following classifications: External inflammatory resorption occurs following prolonged insult leading to continuing pathological resorption. (
  • Also known as transient inflammatory resorption. (
  • Transient inflammatory resorption undergoes healing and should be monitored only. (
  • Inflammatory resorption is associated with detectable inflammation and may be internal or external (apical or cervical). (
  • If the insult is persistent, then resorption continues, and if the tooth tissue is irretrievably damaged, complete resorption may occur. (
  • Within each of a cat's teeth is a chamber (root canal) that contains tissue made up of blood vessels, lymphatic vessels, and nerves. (
  • The course of tooth resorption involves an elaborate interaction among inflammatory cells, resorbing cells, and hard tissue structures. (
  • Instead of decaying, the tooth undergoes resorption, which means that the tissue and enamel is reabsorbed, often below the surface of the gums. (
  • Initially, it appears that the gingival tissue is growing into the tooth or is covering over the base of the tooth as shown in the photo below. (
  • She said, after consulting another dentist that it was either internal or external resorption and for some reason there is gum tissue inside my tooth that is extremely painful when she touches it with a needle. (
  • Do you know why I would have gum tissue inside my tooth with no cracks or way of it getting into there? (
  • I am scheduled to have a root canal on this tooth and am concerned about the gum tissue inside and how that will be done. (
  • Ledermix paste, with its composition of triamcinolone acetonide and demethylclortetracycline, has been shown to inhibit inflammation and the associated hard tissue resorption. (
  • Whatever the underlying cause, the end result is loss of the outer hard tissue of the tooth (enamel, cementum, and dentin). (
  • Type I tooth resorption results in focal loss of dental hard tissue with retention of the periodontal ligament. (
  • Treatment depends on the size and location of the resorption: a small site can often be treated by surgically accessing the tooth through the gum tissue and removing the offending tissue cells. (
  • In some cases, it looks as though gum tissue is growing over or into the tooth. (
  • The AVDC considers operative dentistry to be any dental procedure which invades the hard or soft oral tissue including, but not limited to, a procedure that alters the structure of one or more teeth or repairs damaged and diseased teeth. (
  • Stage 3 has major tissue loss, where the loss is severe enough to expose the root of the tooth. (
  • By stage 5, there are only spotty remnants of hard tooth tissue, and the remains of the tooth have been covered by the gums. (
  • The 3-year recall examination revealed no mobility, soft tissue alterations, or progression of resorption. (
  • Clinical periodontal and implant surgery topics including mucogingival surgery around natural teeth, soft tissue management around dental implants, hard tissue implant site preparation, and use of biologics in periodontal therapy namely regeneration. (

  • But then a report from the Journal of Veterinary Dentistry found the inverse: Out of 64 cats studied, the ones with tooth resorption had much lower vitamin D serum levels than those without. (
  • Esthetic dentistry has been prioritized and the desire for whiter teeth has been increasingly present in dental offices, since whiter teeth tend to indicate health, beauty, youth and a more attractive smile. (
  • These tissues provide protection from resorption when intact and healthy. (
  • Internal tooth resorption is a rare dental condition where the body tries to resorb mineralized tissues such as the dentin and pulpal walls. (
  • The resorption pulls those tissues into the root canal that runs through the center of your tooth. (
  • To keep your body from attacking the tissues within your tooth, your dentist will need to remove those tissues. (
  • In cats, this most often occurs when the tooth breaks and exposes the tissues that lay beneath the enamel. (
  • However, the likelihood that a root canal treatment of an abscessed tooth will be successful depends on the health of the surrounding tissues and the condition of the affected tooth. (
  • Cats can develop problems in the tissues around their teeth just like us! (
  • The oral cavity includes the supportive periodontal tissues of the teeth, as well as the salivary glands and immune tissues (such as tonsils). (
  • When gum infection or inflammation becomes more advanced, the anchoring soft tissues and eventually, the bony sockets can become weak and degraded, leading to loose, lost, or abscessed teeth (periodontitis). (
  • Regardless of the inciting causes, none of which have been well proven, the affected cats' immune system overreacts to plaque bacteria, and/or the tooth or tooth's supportive tissues, leading to severe and often debilitating inflammation (stomatitis). (
  • Root resorption is characterized by an unregulated function between blastic and clastic cells, normally responsible for the maintenance and remodeling of the periodontal support tissues. (
  • Thus, the effective management of these tissues during the treatment of replanted teeth is essential. (

  • The tissues surrounding the apex of a tooth develop a periapical granuloma, cyst, or abscess. (
  • The tissues that form teeth may also spawn cyst or tumor formation. (
  • If an environment exists where dental plaque tends to accumulate (for any reason, ranging from patient neglect to situations that are simply impossible to clean), both the tooth and the tissues that surround it will be at increased risk for problems. (
  • Tooth resorption is classified internally and externally, depending on where the loss of tooth occurs. (
  • Root resorption falls into this latter category: it occurs when a tooth's root structure begins to break down and dissolve (or resorb ). (
  • External resorption usually occurs at the neck-like or cervical area of a tooth around the gum line. (
  • We don't fully understand how root resorption occurs, but we have identified certain factors that favor its development. (
  • Resorption occurs primarily in the maxillary anterior teeth, averaging over 1.4 mm. (
  • While tooth resorption occurs due to the development of abnormal cells that cause destruction of the tooth, the causes of the condition are still difficult to pinpoint for many patients. (
  • Group I: in 5 patients severe root resorption occurred before crown formation of the permanent successor was completed. (
  • Medical history, medication intake, family history, tooth agenesis, root morphology, oral health and habits must be considerate if we do not want jeopardize our patients by severe root resorption. (

  • The aim of this case series report was to evaluate the root resorption of the maxillary incisors after traction until the occlusal plane of the bicortically impacted canines (placed between the two cortical bones in the middle of the alveolar process) located in a complex position using three-dimensional superimposition. (
  • This case series report describes the root resorption of the maxillary incisors after orthodontic traction with NiTi closed coil springs and a heavy anchorage appliance in three cases of bilateral impacted canines located in a complex position (bicortically) near to midline. (
  • Root resorption of the maxillary incisors after the traction of bicortically impacted canines located in a complex position was observed mainly in the apex region, and the amount of root resorption was smaller than 2 mm in all root surfaces. (
  • These bicortically impacted canines, when located in sector 4 or 5, i.e., near the midline, according to the Ericson and Kurol classification [ 10 ] constitute a greater risk for root resorption of the maxillary incisors due to their direct contact. (
  • both skulls of Euchambersia show no sign of any replacement teeth developing, suggesting that Euchambersia was reliant on having both canines present and functional simultaneously. (
  • Behind the incisors and canines, there were no additional teeth in the jaw. (
  • Where teeth would be located in therocephalians that do have teeth behind the canines, there is instead a large depression, or fossa, on the side of the maxilla, which is also bounded below by part of the lacrimal and possibly part of the jugal. (
  • Some teeth undergoing tooth resorption are not clinically apparent until dental radiographs are taken (also shown below). (
  • Dental radiographs are essential in evaluating teeth for resorption. (
  • Diagnosis is made through radiographs of the incisor and canine teeth. (
  • Follow-up with full mouth radiographs should be done annually on any animal diagnosed with tooth resorption. (
  • Tooth resorption may be diagnosed by visual inspection of teeth, tactile observation and most importantly dental radiographs. (
  • There are two main types of tooth resorption identified on dental radiographs in cats - type I and type II. (
  • Patients that have been diagnosed with tooth resorption and those having had crown amputation procedures performed should follow-up dental radiographs performed every 6-12 months. (
  • Panoramic or bite-wing radiographs were selected from a dentition archive of radiographs from 142 children with deviant resorption patterns. (
  • A thorough dental procedure includes examination of every single tooth, probing for tooth mobility, and dental radiographs - and none of that can be done without anesthesia. (
  • Dental radiographs are essential for extracting these teeth because they help the dentist find fractured root fragments. (
  • Methods: Using geometric constructions, governing equations were derived to express the relationships between actual tooth, root and crown lengths, and their image sizes on "before" and "after" radiographs. (
  • Root resorption of the maxillary incisors has been evaluated mainly on radiographs and using scoring systems. (
  • Tooth resorption, or root resorption, is the progressive loss of dentine and cementum by the action of osteoclasts. (
  • A microscopic degree of superficial external root resorption is normal and is usually repaired by cementum. (
  • Tooth resorption in cats begins with a loss of the normal periodontal ligament architecture and focal damage to the cementum that covers the root surface. (
  • Backscattered electron scanning electron microscopy was used to study enamel, cementum and dentine in non-resorbed, undemineralized teeth from adult cats. (
  • Recognize the involvement of cementum and dentin in healing of external root resorption. (
  • Hypercementosis refers to excessive cementum formation above and beyond the extent necessary to fulfill its normal functions, resulting in abnormal thickening with macroscopic changes in the tooth root, which may require the delivery of forces that are different from conventional mechanics in their intensity, direction and distribution. (
  • When deposition takes place prior to tooth eruption the cementum can be classified as primary. (
  • The cementum overlays the root surface, thereby "hiding" or isolating the periodontal ligament dentin and, at the same time, allowing the attachment of periodontal collagen fibers for support and tooth articulation (of the gomphosis type) with the periodontal ligament along the alveolar wall. (
  • We studied an inbred family of Pakistani origin in which two first-cousin born brothers are affected by early tooth loss with peculiar teeth abnormalities characterized by the absence of cementum formation. (

  • The inflammatory type of resorption has the positive aspect that treatment of the cause of the inflammation may halt the resorption. (
  • A burrowing type of resorption is most commonly seen. (
  • Other possible causes of the symptoms are a severe disease of the mouth (lymphocytic plasmacytic stomatitis syndrome) or recession of gums coupled with root exposure (generally considered a different type of resorption). (

  • What pet owners often mistake for a cavity in a cat is something called cat tooth resorption. (
  • I went to the dentist for a small pink looking cavity on my front upper tooth. (
  • There may also be a hole in the tooth, which is why the condition is something incorrectly referred to as a cavity. (
  • However, when the affected tooth is exposed to the oral cavity, microorganisms can invade the dentin through fissures, and cause caries in the resorbed area resulting in pulpal inflammation in severe cases [ 6 ]. (
  • However, cats do get holes in their teeth as a result of tooth resorption rather than classic cavity decay. (
  • Infections of the mouth - Resorption may be caused in some individuals who experience tooth pressure due to infections and inflammatory processes within the oral cavity. (
  • In external cases of resorption, the dentist will drill or cut away the affected part and fill the cavity with some type of permanent material, such as resin or cement. (

  • Your dentist will extract the tooth root and fill the hollow of your tooth, stopping the resorption process and protecting your tooth from further damage. (
  • Equine Odontoclastic Tooth Resorption and Hypercementosis (EOTRH) is a dental disease that can occur as horses age. (
  • Information about orthodontic movement of teeth with hypercementosis is scarce. (
  • What are the unique features and specificities involved in moving teeth that present with hypercementosis? (
  • When there is insult leading to inflammation (trauma, bacteria, tooth whitening, orthodontic movement, periodontal treatment) in the root canal/s or beside the external surface of the root, cytokines are produced, the RANKL system is activated and osteoclasts are activated and resorb the root surface. (
  • So, here is my catch-22: Get the the tooth pulled now and be forced to pay out of pocket for bridge or implant, OR, wait in pain for 2 months, risk damage to adjacent teeth (one may need a root canal just due to the abscess), and be covered for the entire thing? (
  • If tooth resorption is caught early on, the tooth can typically be saved via a root canal. (
  • Tooth resorption begins with a loss of tooth enamel and will eventually spread to the dentin and then the root canal, which contains the blood vessels and nerves to the tooth. (
  • You might have to undergo another root canal in the future, but this is one of the surest ways to save the tooth from resorption. (
  • The tooth root connects to the tooth near the bottom of the root canal. (
  • A tooth root abscess forms when bacteria enter the exposed root canal of the tooth. (
  • The tooth may be saved if a root canal treatment is performed. (
  • Some general practitioners are comfortable performing a root canal treatment on an abscessed tooth, but most veterinarians will refer these complex cases to a veterinary dental specialist ( ). (
  • For internal tooth resorption, dentists will usually perform a root canal to remove all of the diseased areas of the tooth to prevent further deterioration. (
  • When a 9-year-old patient suffered external root resorption after avulsion and reimplantation of the permanent maxillary left lateral incisor, the root canal was obturated with gutta percha and mineral trioxide aggregate. (

  • H-1: There is no difference in the amount of root resorption caused by the three different appliances. (
  • Other signs include increased salivation, inflammation or bleeding around the gum line, severe calculus buildup, missing or fractured/broken teeth, and uncharacteristic malaise. (
  • Inflammation may also play a role in pressure or mechanical root resorption and in the burrowing type of external resorption involving the neck areas of the teeth. (
  • Inflammation is absent, so that treatment, which is difficult, must be directed at the resorption itself. (
  • Cats can get gingivitis, where they have gum irritation and need to have their teeth cleaned of plaque, or they can get stomatitis, where they have serious inflammation and pain, and the tooth may need to be removed. (
  • There is no sign of inflammation of the tooth. (

  • People with minor misalignment may also consider porcelain veneers or contouring, which entails shaving thin layers of enamel to make teeth appear straighter. (
  • If repair does not occur, the resorption progresses into dentin and extends coronally into the crown of the tooth where it undermines the enamel to cause clinically apparent defects on the tooth surface (at the 'neck' of the tooth). (
  • Also known as external cervical resorption (ECR), the condition usually shows first as pink spots where the enamel is being undermined. (

  • In the spaces between the inorganic salts in tooth enamel , these unstable free radicals attach to organic pigment molecules resulting in small, less heavily pigmented components. (
  • [2] The scattering of light and absorption within enamel and dentine determine the intrinsic colour of teeth and because the enamel is relatively translucent, the dentinal properties can play a major role in determining the overall tooth colour. (
