Periodontal disease, in which the support structures of the tooth—cementum, periodontal tissue, ligament, and alveolar bone—are affected 2. Diagnostic imaging (radiography and computed tomography) is indicated in cases of suspected dental disease. Stage 5 (TR 5): Remnants of dental hard tissue are visible only as irregular radiopacities, and gingival covering is complete. Tooth resorption (TR) is defined as resorption (or loss) of dental hard tissue mediated by odontoclasts, cells involved in normal tooth movement and loss of deciduous teeth. We use cookies to help provide and enhance our service and tailor content and ads. Using dental elevators, or small bone gouges and a mallet, the periodontal attachments are broken down until the teeth are loose and can be extracted with forceps. By Alice Ekerdt, DVM The AVDC classification method was relevant in only some teeth and was best used for lesions with radiographic patterns of external replacement resorption and external cervical root surface resorption. Discuss treatment options and prognosis with the client. Stage 3: Deep loss of dental hard tissue (cementum or cementum and enamel with loss of dentin that extends to the pulp cavity); most of the tooth retains its integrity. Signs may include anorexia, ptyalism, lethargy, depression, dysphagia, halitosis, and discomfort during eating or an oral examination. If teeth have more severe resorptive lesions of the apical aspects, apical infection, or dental fractures, all dental fragments must be fully removed even if this involves elevation of the complete labial aspects of the alveolar wall. I am now 55 years old. Type 2 lesions have root resorption and loss of the periodontal ligament. Stage 5 (TR 5): Remnants of dental hard tissue are visible only as irregular radiopacities, and gingival covering is complete. They found that the AVDC classification method (originally developed for cats) was applicable in identifying the extent, but not the radiographic patterns or location of TR lesions. However, in some cases the overlying gingiva may be inflamed (Fig. These teeth are fragile and usually fracture during extraction. Dehiscence of the site commonly occurs, but most will soon heal by secondary intention without a problem.21, Cecilia Gorrel BSc MA VetMB DDS MRCVS HonFAVD DipEVDC, ... Leen Verhaert DVM Dipl. Find yours today. (978) 687-7453 All alveoli are fully curetted to remove any residual dental tissue, lavaged with saline, and then allowed to fill with blood clots. Stage 5: Remnants of dental hard tissue are visible only as irregular opacities on radiographs, and gingiva completely covers the remanant of the resorbing root. External inflammatory resorption usually requires extraction, but root canal therapy is occasionally an option. Stage 3 lesions affect the pulp cavity, but most of the tooth retains its integrity. Teeth were autogenously transplanted by the 2-stage technique in adult patients and examined up to 5 years after surgery for the prevalence of, and correlation between, tooth graft loss, root resorption, ankylosis, periodontal attachment loss, tooth mobility, and pain. It has also been reported in dogs (Arnbjerg 1996) and in the chinchilla (Crossley et al. When replacement resorption progresses coronally toward the gingival attachment, an inflammatory element may join the originally non-inflammatory lesion, and both replacement and inflammatory resorption will be present on the same tooth. The incidence of TR in canines increases with age and body weight. AKA Type 2 TR in cats. Resorption of teeth is common in domestic cats. Sharp dental spur formation might be easily overlooked, particular if arising from the maxillary cheek teeth and directing buccally (Fig. The syndrome of equine odontoclastic tooth resorption and hypercementosis (EOTRH)20 is now diagnosed in many older horses. There is no obvious predisposition with regard to gender, breed, or neuter status. Sometimes feline tooth resorption leads to the appearance of a hole in the tooth. 1. Peralta, et al. The models included periodontal ligament, bone, and soft tissues. This disease differs from: 1. 5 Veterinarians evaluate each tooth to determine the type and stage of each lesion. Teeth are not symptomatic in the early stage of resorption. All information is peer reviewed. Treatment is controversial because of the progressive nature of the lesions. There is a significant positive association between external replacement resorption, age, and body weight in affected dogs. Radiography or CT are the only diagnostic methods to evaluate for subgingival disease, such as alveolar bone or tooth resorption (Fig 22.13L), apical elongation of the reserve crown and periodontal infections.55. By continuing you agree to the use of cookies. Practice Limited to Dentistry and Oral Surgery Oval-shaped enlargement in the cervical 1/3 of the root canal, Irregular enlargement with tunnel-like appearance adjacent to the root canal. Stage 5 (TR 5): Remnants of dental hard tissue are visible only as irregular radiopacities, and gingival covering is complete. Idiopathic tooth resorption is seen in up to two-thirds of domestic cats and increases in frequency with age.24–27 Because lesions are painful and progressive regardless of attempts to treat conservatively28, extraction is the currently recommended treatment for teeth affected by resorption. Differential diagnoses for dyspnea in prairie dogs include elodontoma, bacterial respiratory infection, obesity, cardiac disease (cardiomyopathy, congestive heart failure), pulmonary mites, and mediastinal mass. Patients should be continued on a broad-spectrum antibiotic and fed soft mashes for a couple of weeks. This is a normal physiological process in the exfoliation of the primary dentition, caused by osteoclast differentiation due to pressure exerted by the erupting permanent tooth.However, in the secondary dentition the process is pathological. It is possible to miss the symptoms of dental resorption until the disease has progressed to a more serious stage. 11.2A).29,30 Age-related root resorption, seen in up to 43% of dogs aged 12–14 years,6 does not affect the crowns, and extraction is generally not indicated for teeth with root resorption in the absence of coronal lesions (Fig. 24/7 Emergency & Critical Care in Waltham, Veterinary Clinic for Low Income Pet Owners, Veterinary Clinic for Low-Income Pet Owners and the General Public, Discounted Services for Low-Income Clients, 350 South Huntington Avenue, Boston, MA 02130, 1577 Falmouth Road, Centerville, MA 02632, https://www.dvm360.com/view/tooth-resorption-name-it-tame-it-your-veterinary-patients. The goals of therapy include reducing periodontal infection and soft tissue trauma, which both lead to discomfort and pain, and recovering or maintaining the animal’s ability to eat unaided. (Source: Animal Dentistry and Oral Surgery Specialists, LLC) Treatment of tooth resorption. I saw the dentist in April, no problem. Stage 4 – These have deep erosions with loss of tooth integrity as well as endodontic involvement. These spikes frequently lead to ulceration of the buccal mucosa (Fig. Type 2 lesions are monitored visually and radiographically (every 6 to 12 months) for continued resorption or changes requiring further treatment. However, RLs should not be confused with dental caries. Peralta, et al. Using the guidelines in this article, tooth resorption can be diagnosed based on intraoral radiographs and a thorough examination. Treatment in dogs, similar to that in cats, depends on the type, location, and stage of tooth resorption in addition to the entire clinical picture. There are seven types of tooth resorption in dogs, as determined by radiographic appearance: external surface resorption, external replacement resorption, external inflammatory resorption, external cervical root surface resorption, internal surface resorption, internal replacement resorption, and internal inflammatory resorption (see the following images and descriptions). Radiographs of teeth affected with TRs show distinct changes. E. Stage 5: no remaining tooth crown, gingiva completely covers site. [email protected] Crown amputation can be performed if the resorption is extensive and there are no signs of periodontitis, endodontic disease, or periapical disease. Both types of lesion can be found in the same individual cat, and even in the same tooth with one root appearing to be type 1 and the other root appearing to be a type 2 (Figure 7-12). External inflammatory resorption was found most commonly in the maxillary 4th premolars. In the absence of pulpitis and periapical inflammation, however, tooth resorption apical to the gingival attachment is thought to be asymptomatic. A continuous incision is made in healthy gingiva 5 mm from the gingival margin of the affected teeth, on both the labial and the lingual/palatal aspects. The process usually starts in the enamel along the gum line and continues towards the center of the tooth. Related terms: . Over time, all areas of an affected tooth, from root to crown, may become involved. Stage 5 Remnants of dental hard tissue are visible only as irregular radiopacities, and gingival covering is complete. This can result in dentoalveolar ankylosis (fusion of the tooth to the bone). More Info, 1577 Falmouth Road, Centerville, MA 02632 However, periodontal disease, caries, and tooth resorption are disease processes that frequently occur in chinchillas but are often missed during intraoral examination, even with general anesthesia.55 Evaluation of 181 captive chinchilla skulls found signs of periodontal disease in 63% and dental caries lesions in 52%, characterized by brown discoloration and loss of tooth substance on occlusal and interproximal tooth surfaces due to a bacterial infection leading to demineralization (Fig. Tooth resorptionis a process by which the dentin in a single tooth—or several teeth simultaneously—erodes and eventually becomes irreparably destroyed. Padraic M. Dixon, Mathew P. Gerard, in Equine Surgery (Fifth Edition), 2019. Extraction or root canal therapy are the treatments of choice for a few other types of resorption. Lesions in which the roots are not replaced by bone-dense tissue are termed type 1 lesions (Figures 7-7 through 7-10), while those in which the roots are replaced and appear to disappear are type 2 lesions (Figure 7-11). General oral examination may demonstrate suspicious lesions. Preventing Teeth Resorption Clean your cat's teeth regularly. also investigated the prevalence of different stages of TR in dogs. Gregg A.

More Info, 293 Second Avenue, Waltham, MA 02451 The prognosis for chinchillas diagnosed with dental disease depends on the severity, the animal’s general condition, and owner compliance. For low resolution printer-friendly versions of the full sets of tooth resorption images, click TR Diagrams or TR Clinical Images . Stage 4 lesions have significant crown or root damage, with most of the tooth having lost its integrity. Extraction is the only treatment for tooth resorption. This type of TR also commonly demonstrates concurrent periodontal or endodontic disease. Stage 5: Remnants of dental hard tissue are visible only as irregular opacities on radiographs, and gingiva completely covers the remanant of the resorbing root. If you click on a link on this page and make a purchase, we may receive a … What happens during tooth resorption? Oral pain is the best indicator that your cat might be suffering from one or more FORLs. vet., Diplomate ACZM, Diplomate ECZM (Zoo Health Management), Thomas M. Donnelly BVSc, Diplomate ACLAM, Diplomate ABVP (Exotic Companion Mammal), Diplomate ECZM (Small Mammal), in Ferrets, Rabbits, and Rodents (Fourth Edition), 2021, Dental disease is a common diagnosis in pet chinchillas of all ages (see Chapter 36). Loss of tooth substance and mobility of the clinical crowns are consequences of resorption of the reserve crowns (Fig 22.13L), whereas brown discoloration of occlusal and interproximal tooth surfaces is seen in cases of caries (Fig 22.13I).17,43,55 Evaluate radiographs or, preferentially, CT scans of the skull in any chinchilla with a history or clinical signs suggestive of underlying dental disease. found the prevalence of tooth resorption in dogs to be 53% with external replacement resorption being the most common type at 34%. The most commonly affected teeth include the mandibular third premolars; however, any tooth can be affected. Resorptive lesions may be type 1 or 2. According to Reiter, tooth resorption is aymptomatic if it does not involve inflammatory cells, remains below the gingival attachment (protected from oral bacteria), and does not affect the pulp. The process starts in cementum and progresses to involve the dentine, where it spreads along the dentine tubules and eventually comes to involve the dentine of the crown as well as the root. angell.org/dentistry B. Tooth resorption has also been shown to occur in feral ( Verstraete et al. It is not known if the dissimilarity between the two types is caused by different etiologies, or if it is a result of inflammation interfering with bone repair and tissue replacement, or if some other physiological process acts on one type of lesion but not the other. Stage 5: Remnants of dental hard tissue are visible only as irregular opacities on radiographs, and gingiva completely covers the remanant of the resorbing root. 22.13).16 Nutritional (e.g., inappropriate dietary Ca/P ratio) and genetic causes have been proposed as predisposing factors.55, Common clinical findings associated with dental disease in chinchillas are reduced body condition and weight loss secondary to reduced food intake, changed food preferences toward more easily chewed feed items, weight loss, reduced fecal output with smaller, irregularly shaped fecal pellets, saliva-stained skin and fur with crusting and alopecia of the perioral area, wetting and crusting of the chin (“slobbers”) (Fig 22.9) and forefeet, epiphora, poor fur condition, and fur chewing.17,43,55 On clinical examination, palpable irregularities of the ventral borders of the mandible and overgrown depigmentation of the orange labial surface of the incisor teeth may be found (Fig 22.3B).17,55 Facial abscesses of periodontal origin are seen infrequently but can occur.43,55, A limited examination using a pediatric laryngoscope, otoscope, or vaginal speculum can be performed in a conscious animal, but up to 50% of intraoral lesions can be missed, in particular periodontal disease, tooth resorption, and buccal spurs of the maxillary cheek teeth.44 Instead, perform a thorough examination of the oral cavity under general anesthesia. Some cats present with oral discomfort, lethargy, anorexia, dehydration, and weight loss. Over time it becomes more evident on radiographs which areas will be replaced and which are associated with pathology (Figures 7-13 through 7-15). The PDL space and lamina dura are unaffected. If there is too much tooth resorption, they may even extract the tooth. The exact causes of tooth resorption are not fully understood, but mastication forces, orthodontic forces, and even the presence of oral tumors at distant sites have been proposed. The offered diet should be optimized to minimize the recurrence of the condition.7,38. Similar to cats, dogs suffering from resorptive disease will often exhibit a pink spot of tissue on an affected tooth. Lesions begin as a superficial resorption of tooth substance often at or close to the cemento-enamel junction. Histopathology is the gold standard for differentiating types of tooth resorption, but it is impractical in a clinical setting. I have been a faithful attendant to my teeth all my life — checkups twice a year. They will also typically experience significant pain during the oral exam. When there is little resorption and much hypercementosis, the teeth are often stable and pain free and usually do not need treatment. Stage 5 (TR 5) is typified by remnants of dental hard tissue that are visible only as irregular radiopacities. It is unknown if this is a stage of severity in which the root or region with the appearance of a type 1 lesion might have eventually progressed to become a type 2 lesion. Using a wide dental elevator or a small osteotome, the gingiva is elevated in two large flaps above the alveoli of the affected teeth, and the labial alveolar wall is removed (using a high-speed drill or osteotome), but not necessarily as far as the apical region, to facilitate extraction. What is the treatment for tooth resorption? However, the differences are radiographically detectable and may become important in the search for the etiology and pathophysiology of TRs.

Amputate crowns of type 2 lesions when no other disease present, Stage 2 or 3 lesions on canine teeth: restoration until lesion reaches stage 4. EVDC, in Veterinary Dentistry for the General Practitioner (Second Edition), 2013. (Descriptions from reference #5) Treatment in dogs, similar to that in cats, depends on the type, location, and stage of tooth resorption in addition to the entire clinical picture. Email Us, 350 South Huntington Avenue, Boston, MA 02130 Classifying the type and stage of tooth resorption allows us to treat properly and relieve discomfort in our patients. The roots of some affected teeth seem to “disappear” as they lose radiodense root tissue at a similar rate to the simultaneously occurring osseous repair, effectively making the roots appear to blend with the surrounding bone. After removing spurs and reducing elongated crowns (see Chapter 36), probe interproximal spaces and periodontal pockets and remove impacted debris. by Peter Mayhew | Jul 26, 2018. Replacement resorption is often associated with tooth root ankylosis and hypercementosis. Historically dental disease in chinchillas mainly has been referred to as malocclusion and elongation of the cheek teeth. Learn about ways we provide Compassionate Access to Resources, Education and Services. Tooth resorption, or root resorption, is the progressive loss of dentine and cementum by the action of osteoclasts. Root resorption in adults is usually indicative of an underlying tooth injury that may cause long-lasting damage and even a complete loss of the teeth. External cervical root surface resorption is only treated by extraction of the tooth. In these cases, perform dental examination with the animal anesthetized; the oral cavity and the teeth can be further evaluated by using an otoscope or endoscope. 5 teeth, respectively.7 A different study also provides evidence suggesting that TR lesions mostly occur with mandibular third premolars.11 The root resorption requires two phases: injury and stimulation. Melissa T. Hines, in Equine Internal Medicine (Fourth Edition), 2018, Equine odontoclastic tooth resorption and hypercementosis, Oral, esophageal—squamous cell carcinoma, dental, Retropharyngeal masses causing compression, Hemorrhage associated with rupture of the longus capitus, Christoph Mans Dr. med. More Info, 400 Broadway, Methuen, MA 01844 Stage 4 — During this stage, most of the tooth has been destroyed by the resorptive lesion. In addition, your dog may exhibit these signs if she has resorpt… These dogs must be sedated so every tooth can be examined for lesions, and dental X-rays should be performed to check below the gum line or within the tooth for other signs of resorption. Stage 4: significant destruction of tooth crown. These types are both self-limiting processes and do not require treatment. For on-site assistance (check-ins and pick-ups): 10.60).32, Tooth resorption is rarely seen in cats younger than 2 years of age, and clinically obvious disease may not be noted before the cat is 4 to 6 years of age. Or in the early stages of resorption, while the affected area is small, a dental surgeon might expose the damaged area through minor gum surgery and remove the cells that caused the damage. Diagnosis and treatment of each type is directed by the radiographic appearance. Internal resorption originates from within the pulp cavity while external resorption originates from the outside surface of the tooth. Eventually, the tooth will be almost entirely gone. Ellen I. Logan, in Handbook of Small Animal Practice (Fifth Edition), 2008. 1996; Clarke and Cameron 1997) and wild cats (Berger et al. Altier is not familiar with any studies that provide a definitive answer on … Clinical Approach to Commonly Encountered Problems, Equine Internal Medicine (Fourth Edition), Ferrets, Rabbits, and Rodents (Fourth Edition), ). Stage 5 lesions have remnants of dental hard tissue visible only as irregular radiopacities, and gingival covering is complete. Resorptive lesions (RLs) occur as a result of an external root resorption, where the hard tissues of the root surfaces are destroyed by the activity of multinucleated cells called odontoclasts. While less common in dogs, resorption involving both crowns and roots has also been reported (Fig. Current recommendations are as follows (DuPont, 2005): Debride tissue from defects and etch with acid. Other TRs retain areas of normal radiodensity interspersed with radiolucencies caused by resorption and do not lose the detail of the periodontal ligament space and root structures in those areas not directly undergoing resorption. Stage 5 — Finally, the gums grow over the small amount of dental tissue that remains. Feline stomatitis, an im… Feline Tooth Resorption Stage 4c Root is more severely affected than the crown. [email protected] The peripulpal dentine is relatively resistant to resorption and the pulp thus only becomes involved late in the disease. Other common intraoral findings involving the cheek teeth are widened interproximal spaces, which facilitates food impaction and promotes development of periodontal disease. Captive prairie dogs are often presented for dental-related disease and sometimes secondary upper respiratory signs with respiratory distress. 11.2B). Advanced lesions located on the crown are readily evident. (617) 522-5055 Stage 5 – These are chronic lesions, which have caused complete coronal loss and subsequent gingival over-growth hiding the retained root. Halitosis, plaque and calculus accumulation, gingivitis, and gingival enlargement in areas of crown defects may be noted. The two most common lesions reported were external replacement resorption (34.4%) and external inflammatory resorption (25.9%). Gingival covering is complete (Photo 12). Captive prairie dogs offered a suboptimal diet (human food, low fiber) will commonly develop incisor malocclusion and sometimes secondary cheek tooth resorption. Internal inflammatory resorption can be treated by resolving the underlying disease, often leading to extraction or root canal therapy in select cases. (See Stages of TR below, descriptions and images), AVDC Description of Tooth Resorption Stages, Stage 1: Mild loss of dental hard tissue (cementum or cementum and enamel). Infection is the main stimulation factor in IRR. It can be classified based on severity, location, and radiographic appearance. Tooth resorption on the canine teeth of cats often have areas that appear to be combined type 1 and type 2. (978) 577-5992 It Can be Symptom-Free. Endoscopic-guided intraoral examination (stomatoscopy) provides superior visibility and increases the chance for detection of pathologic lesions and is considered a necessity by the authors for a complete intraoral exam in chinchillas.55, Inspect all cheek teeth for evidence of crown elongation, malocclusion, malposition, mobility, periodontal disease as well as caries and resorptive lesions (Fig 22.13). Stage 2: Moderate loss of dental hard tissue (cementum or cementum and enamel with loss of dentin that does not extend to the pulp cavity). [email protected] Type 1 lesions have an identifiable root and periodontal ligament. Furcation (junction of roots) exposure from periodontal disease. The teeth developed internal resorption.
