A 9-year-old, male North African leopard (Panhtera pardus) presented with mandibular brachygnathism and lingually displaced mandibular canine teeth causing a large left oronasal fistula, rhinitis and nasal discharge, and a right orocutaneous fistula. Surgical closure of the left oronasal defect, bilateral mandibular canine tooth crown reduction, and root canal therapy resulted in a positive clinical outcome. A small recurrent left oronasal fistula and the right orocutaneous fistula healed spontaneously after alleviating the occlusal contact with the mandibular canine teeth. At 12-months postoperatively, clinical signs of oral and dental disease had resolved. 相似文献

The etiology of tooth resorption in the domestic cat remains unknown. The high prevalence and progressive nature of the disease complicates defining healthy control groups. In order to evaluate the possible influence of various life style changes on the prevalence of tooth resorption, healthy control groups are a prerequisite. This paper presents a prevalence study for tooth resorption in a free-ranging wild felidae population. Skulls from 46 free-ranging Eurasian lynx (Lynx lynx) were examined. The age of the animals had previously been estimated based on cementum annuli in the maxillary right canine tooth. The dental examination included both dental probing and radiographic imaging. Complicated fractures of the canine teeth were found in 9/46 (19.5%) skulls. In one fractured canine, apical root resorption and periapical lucency was detected. The root resorption was attributed to inflammatory resorption as a consequence of the initial dental trauma and necrotic pulp. No signs of tooth resorption were found in the remaining teeth. Supernumerary roots were detected in 18/46 skulls (39.1 %). Supernumerary "peg" teeth caudal to the mandibular first molar tooth were detected in 6/46 (13.0%) skulls. Although further studies on dental ultra-structure are needed, the Swedish Eurasian lynx may, in the future, be useful as a healthy comparative model for studies on the etiopathogenesis of tooth resorption in the domestic cat. 相似文献

Allogeneic tooth transplantation was evaluated as a functional and aesthetic treatment for dental fracture in the dog. Of 7 dogs that received tooth transplants, 5 were research animals and 2 were clinical patients. Canine teeth were transplanted immediately after extraction in the research dogs. Endodontic therapy had been performed on the affected canine tooth of one clinical patient. The other clinical patient had bilateral maxillary canine fractures 2 months earlier. One of the research dog transplants failed at 3 weeks as a result of improper surgical technique. Four of the research dogs had a solid implant for 18 months, after which time the dogs were euthanatized serially. All transplanted teeth were anchored firmly into the alveoli, but were nonviable. Root resorption, with bone replacement, was first noticed at 24 months. The transplanted tooth in the first clinical patient remained functional for 3 months, after which time the tooth was fractured. The right canine transplant in the second clinical patient failed by 3 months, probably because of preexisting periapical inflammation. The left transplanted tooth remains stable at 38 months. It was concluded that allogeneic tooth transplantation may have merit as a rapid and inexpensive method for replacement of fractured teeth in the dog. Function is compromised gradually as a result of root resorption and ankylosis, with tooth fracture likely to occur after 2 years. 相似文献

A 10‐year‐old, castrated male domestic short hair cat was presented to the Small Animal Clinic at the Western College of Veterinary Medicine with a presenting complaint of chronic, ocular discharge from the left eye. Ocular examination confirmed epiphora and mucopurulent discharge but there were no apparent reasons for the ocular discharge, and nasolacrimal obstruction was suspected. The cat had swelling of the left side of the face, severe periodontal disease and a fractured upper left canine tooth with pulpal exposure. Dacryocystorhinography revealed narrowing of the nasolacrimal duct above the root of the fractured upper left canine and dental radiographs showed a severe periapical lucency at the apex of the upper left canine tooth. The fractured canine tooth was removed. Subsequently, the ocular discharge and facial swelling resolved. After 2 years, the epiphora has never reoccurred. This is a noteworthy case because a suspected root abscess resulted in extralumenal compression of the nasolacrimal duct, which shows the importance of a thorough oral examination when nasolacrimal obstruction is evident. 相似文献

A dentigerous cyst was diagnosed in the right rostral maxilla of a 6-month-old Siamese cat affecting the maxillary right canine tooth. The deciduous maxillary right canine tooth was extracted and the dentigerous cyst wall was curetted. The permanent tooth was not removed, however it was mobile following the surgical procedure. Examination 6-months following surgery indicated appropriate development of the tooth with no mobility or periodontal pocket formation. The maxillary right canine tooth had an abnormal shape but was functional with an acceptable appearance. 相似文献

A 7-month-old castrated French bulldog was presented with a left-sided mandibular tumor. The initial tumor biopsy diagnosis was ameloblastoma. The owner brought this dog the Kitasato University Veterinary Teaching Hospital for more detailed examination and treatment. Computed tomography revealed a tumor on the left lateral mandibular gingiva from the caudal third of the incisor tooth to the right canine tooth, associated with severe amorphous osteolysis of the mandibular bone. The tumor was surgically excised and diagnosed as papillary squamous cell carcinoma. Currently, 2514 d (6.9 y) since the operation, the dog is healthy, without recurrence.Key clinical message:Although papillary squamous cell carcinoma is rare, many cases have been reported in the oral cavity of medium-to large-sized dogs. Based on this report, papillary squamous cell carcinoma can occur in small dogs such as young French bulldogs and a good prognosis can be achieved with proper resection. 相似文献

A 5-year-old female neutered Boxer dog was diagnosed with extensive odontogenic cysts that affected the left and right mandibles. Rostral mandibular swelling was detectable clinically, and bilateral cystic mandibular lesions were identified radiographically. The dog's owners elected for euthanasia. A full postmortem was performed. Cystic cavities were confirmed in the body of each mandible, extending from the incisor teeth to the mid premolar region. Incisor, canine, and premolar tooth roots indented each cavity. Histologic examination of the cystic cavities reflected an inner lining of attenuated stratified squamous epithelium overlying a fibrous layer infiltrated by a mixed, predominantly mononuclear, inflammatory infiltrate. 相似文献

A 12-week-old kitten was presented for symphyseal separation, comminuted rostral fractures of the mandibles, avulsion of the mandibular lip, andfractured teeth. Oral examination and intraoral dental radiographs demonstrated a mandibular symphyseal separation and the presence of developing tooth buds. Cerclage wire was placed circumferentially around the mandibles for 2-weeks to provide stabilization of the mandibular symphyseal separation. Clinical examination 9.5-months following surgery demonstrated normal occlusion with enamel hypoplasia affecting the mandibular canine teeth. Intraoral dental radiographs showed a partial bony union of the mandibular symphysis and vital, developing mandibular canine teeth. 相似文献

SUMMARY An 18-months-old neutered male cat was presented for veterinary examination because of a rapidly enlarging mass in the region of the right upper canine tooth. Radiological examination showed displacement of this tooth and destruction of the right maxilla. Post mortem and histopathologic examination confirmed that the mass was a tumour, an adamantinoma. 相似文献

Canine tooth fracture is common in dogs. Application of an esthetic and durable restoration may be challenging in veterinary dental practice. This study used traditional human dental laboratory methods to evaluate fracture strength of intact dog canine teeth and fractured teeth that had been restored by reattachment of the tooth fragment. The results showed that the teeth restored by reattachment of the tooth fragment supported a test load equal to 45.4 % of the load necessary to fracture intact canine teeth. 相似文献

A 6-month-old Bassett Hound dog presented for evaluation of recurrent oral bleeding and a right maxillary swelling. Oral examination revealed right maxillary enlargement extending from the level of the right maxillary canine tooth to the area of the second and third premolar teeth. A discolored persistent right maxillary deciduous canine tooth and gingival inflammation was noted. Biopsies taken at the time of extraction of the persistent deciduous canine tooth resulted in significant hemorrhage and a biopsy report of reactive bone. The right maxillary enlargement did not resolve following the extraction procedure and empirical antimicrobial therapy. The owner elected euthanasia and post-mortem evaluation. Histopathologic assessment provided a diagnosis of maxillary hemangioma. 相似文献

Objective : To determine the effect of unilateral condylectomy on dental occlusion in cats. Methods : Twelve feline cadaver heads were randomly submitted to either a right or left unilateral condylectomy of the temporo‐mandibular joint. The distance between the mandibular and maxillary canine tooth was measured before (B0) and after the unilateral condylectomy (P0). A right or left latero‐‐lateral standardised force (4 N) was applied to the mandibular mentus area before and after the surgical procedure. These measurements were analysed with a linear model for repeated measures. Results : The comparative analysis between pre‐ and postsurgical values indicated no significant variation in teeth displacement following condylectomy between B0 and P0 measurements. Statistically significant differences were detected after either left or right condylectomy with respect to all measurements after application of the standardised forces. Occlusion changes are significant when comparing bites before and after surgery. Clinical Significance : Unilateral condylectomy causes a significant increase in latero‐lateral amplitude of jaw movement which might clinically affect feline dental occlusion. Clinical studies are required to determine the effect of unilateral condylectomies on mastication and dental occlusion in feline patients. 相似文献

A 14-month-old spayed female domestic short-haired cat was presented for evaluation of a rostral mandibular mass diagnosed from biopsy as an ameloblastic fibroma. Radiographs of the mandible demonstrated marked osteolysis and cortical expansion. A rostral mandibulectomy was performed extending from the caudal edge of the second premolar on the right side to the caudal edge of the canine tooth on the left side. Histological evaluation of the excised mass confirmed the diagnosis of ameloblastic fibroma. Follow-up evaluation at eight months revealed normal oral function with the exception of occasional saliva soiling of the chin. The owner was satisfied with the cosmetic result. 相似文献

OBJECTIVE: To determine the diagnostic value of 2 intraoral bisecting angle radiographic views in comparison with periodontal probing for the assessment of periodontal attachment of the canine teeth in dogs. STUDY POPULATION: 466 canine teeth from 117 dogs. PROCEDURE: Periodontal probing measurements were recorded, and clinical attachment levels (CAL) were calculated at the mesial, buccal, distal, and lingual (or palatal) surfaces on each canine tooth. Occlusal and lateral radiographs of the canine teeth were obtained. Alveolar margin height (AMH) was measured at the same 4 surfaces. Values for AMH and CAL were compared on the basis of tooth surface, dental arch, and radiographic view. RESULTS: The AMH at the mesial and distal surfaces of the mandibular canine teeth was measurable on the lateral view and was significantly correlated with CAL. Similar results were found for the mesial and distal surfaces of the maxillary canine teeth. Buccal and lingual AMH were measured on the mandibular occlusal radiographic view, and values were significantly correlated with CAL, but only the buccal AMH could be assessed on the occlusal radiographic view of the maxilla with values that correlated significantly with CAL. CONCLUSIONS AND CLINICAL RELEVANCE: The lateral radiographic view is suitable for evaluating periodontal attachment at the mesial and distal surfaces of the canine teeth in dogs. The occlusal radiographic view is suitable for assessing buccal surfaces as well as the lingual surface of mandibular canine teeth but not the palatal surface of maxillary canine teeth in dogs. 相似文献
