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 ...
