Objective--To identify risk factors associated with survival in dogs with nontonsillar oral squa-mous cell carcinoma (OSCC) that were and were not treated with curative-intent surgery. Design--Retrospective case series. Animals--31 dogs with OSCC. Procedures--Medical records for dogs with OSCC that were not treated, or were treated with curative-Intent surgery only between January 1990 and December 2010 were reviewed. For each dog, data regarding signalment, clinical stage, treatment, tumor recurrence, and survival time were obtained from the medical record, and archived biopsy specimens were evaluated to identify the histologic subtype of the tumor and extent of tumor-associated inflammation (TAI), perineural invasion (PNI), and lymphovascular invasion (LVI). Results--Risk of death for the 21 dogs with OSCC that were surgically treated was de-creased 91.4% (hazard ratio, 0.086; 95% confidence interval, 0.002 to 0.150), compared with that for the 10 dogs with OSCC that were not treated. The 1-year survival rate was 93.5% and 0% for dogs that were and were not surgically treated, respectively. Risk of death increased significantly with increasing TAI and increasing risk score (combination of TAI, PNI, and LVI).Tumor location, clinical stage, and histologic subtype were not associated with survival time. Conclusions and Clinical Relevance--Results indicated that the prognosis for dogs with OSCC was excellent following surgical excision of the tumor. Risk of death increased with increasing TAI, and combining TAI, PNI, and LVI into a single risk score may be a useful prog-nostic indicator for dogs with OSCC. [ABSTRACT FROM AUTHOR]

Objective--To document the short- and long-term outcomes of surgical endodontic treat-ment in dogs in a clinical setting. Design--Retrospective case series. Animals--15 dogs that underwent surgical endodontic treatment. Procedures--Medical records of dogs that underwent surgical endodontic treatment at 3 institutions from January 1995 to December 2011 were reviewed. Information extracted included signalment, history, initial clinical signs, physical and radiographic examination findings, treatment, and outcome. Outcome was determined through evaluation of the pre- and postoperative radiographs as well as clinical and radiographic findings at follow-up evaluations. On the basis of radiographic findings, treatment was considered successful if the periapical lesion and bone defect created by surgery had completely healed and no new root resorption was detected; a treatment was considered to have no evidence of failure if the periapical lesion remained the same or had not completely resolved and root resorption was static. Results--15 dogs were treated by means of apicoectomy and retrograde filling following a failed or complicated orthograde root canal treatment. The mean long-term follow-up time was 15.2 months (range, 3 to 50 months). On radiographic evaluation, 10 of 15 dogs had suc-cessful resolution of the periapical disease; 5 dogs had no radiographic evidence of failure of endodontic treatment. All dogs were considered to have a successful clinical outcome. Conclusions and Clinical Relevance--Surgical endodontic treatment was an effective op-tion for salvaging endodontically diseased but periodontally healthy teeth of dogs in which orthograde treatment was unsuccessful and nonsurgical retreatment was unlikely to suc-ceed.

The article presents a case study of a 7-year-old castrated male Pug with chronic nasal discharge and respiratory distress. Physical examination of the pug revealed hyperemia while a severely elongated soft palate and everted laryngeal saccules was observed on laryngeal examination. Computed tomography imaging of maxillas showed presence of foreign body-associated intranasal abscess. Transpalatal rhinotomy, tooth remnant removal and biopsy was then performed on the pug.

The article presents a case study of a 10-year-old castrated male Staffordshire Terrier presented with an acute onset of pain and swelling that involves the rostal aspect of the left mandible. A substantial firm swelling of the ventral aspect of the left mandible was observed during oral examination. It performs intraoral radiography and periodontal charting. Radiographic results show the presence of an unerupted tooth which suggests a dentigerous cyst with secondary infection.
