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 ...

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 ...

Its so difficult to tell, and the jury is still out in the cause of resorptive lesions. I have Faraday on a mix of a really good wet food, grain free, and a freeze dried raw that has vitamin D3 listed as one of the very last ingredients. I heard back from the manufacturer of the Natural Balance food and it is very balanced in its D3 amount. Faraday has done much better this year, although Maxwell lost his two upper fangs. Then again, Maxie is my kibble addict, do maybe that cubes into play? I hope your baby dudes well with her extractions.

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 ...

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 ...

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 ...

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 ...
OMIM : 58 Hyper-IgE recurrent infection syndrome-3 is an autosomal recessive immunologic disorder characterized by childhood onset of atopic dermatitis, skin infections particularly with Staphylococcus aureus, recurrent sinopulmonary infections, and increased serum IgE and IgG.

A hallmark of the syndrome is an increased concentration of immunoglobulin E in the serum, exceeding 2000 U/ml, frequently higher than 5000 U/ml, and in single cases even exceeding 100 000 U/ml [5, 7, 34]. A value of 2000 U/ml is considered to be the cut-off point, which has proved helpful in establishing a definitive diagnosis of the syndrome [6]. Nevertheless, not in all patients, particularly in infants, are these criteria fulfilled; although characteristic concentration of IgE may be expected in the third decade of life or even later. Typically in adulthood, in a subset of patients IgE levels may decrease with age and may fall within a normal range in about 20% of cases [34]. Interestingly, the severity of infectious complications in patients with hyper-IgE syndrome do not correlate with immunoglobulin E concentration in the serum. Muhammed [81] reported on two HIES pediatric patients presenting with recurrent cutaneous lesions, severe respiratory infections and moderately elevated levels of ...
