Dental and oral diseases are prevalent in many mammalian species including wild felids. Determining the dental and oral health status of captive animal populations can help establish preventive and therapeutic strategies, leading to improved welfare and conservation efforts. The aim of this study was to assess the prevalence of periodontal disease, endodontic disease, tooth resorption, and other clinically relevant dental and maxillofacial abnormalities in a population of captive jaguars () using clinical, radiographic, and histopathological findings. Fifteen jaguars, ranging from young adult to geriatric, kept at a private zoo in Belize, Central America, had a detailed oral examination under general anesthesia between January 2015 and March 2019. Periodontitis was present in 3.8% (16/423) of examined teeth and 53.8% (7/13) of jaguars that underwent periodontal probing. Endodontic disease secondary to dentoalveolar trauma was found in 21.0% (89/423) of teeth in 73.3% (11/15) of animals. Tooth resorption, which has not been previously documented in jaguars, affected 1.4% (6/423) of teeth in 13.3% (2/15) of jaguars. Other abnormalities included metallic foreign material (gunshot) identified radiographically in 33.3% (5/15) of jaguars and nontraumatizing malocclusion in 9.1% (1/11) of jaguars that had occlusion evaluated. Much of the oral pathology identified in captive jaguars is suspected to arise from capture and/or captivity-associated behaviors, as suggested by gunshot around the oral cavity, fractures of rostral teeth (canine and incisor teeth), and abrasions consistent with cage-biting on canine teeth. Anesthetized oral examination-including full-mouth intraoral radiographs, periodontal probing, and charting-is recommended for jaguars with clinical signs of oral pain, as well as for routine systemic evaluation.
口腔疾病在包括野生猫科动物在内的许多哺乳动物中很常见。评估圈养动物群体的口腔健康状况有助于制定预防和治疗策略,从而提高动物福利和保护工作。本研究旨在使用临床、放射学和组织病理学检查结果,评估中美洲伯利兹一家私人动物园圈养的 15 只美洲虎()的牙周病、牙髓病、牙齿吸收和其他临床相关的口腔和颌面异常的流行情况。15 只年龄从青年到老年不等的美洲虎在 2015 年 1 月至 2019 年 3 月期间全身麻醉下进行了详细的口腔检查。在接受检查的 423 颗牙齿中,有 3.8%(16/423)患有牙周炎,在接受牙周探查的 13 只美洲虎中,有 53.8%(7/13)患有牙周炎。由于牙牙槽创伤引起的牙髓病在 73.3%(11/15)的动物中,423 颗牙齿中有 21.0%(89/423)患有这种疾病。在 13.3%(2/15)的美洲虎中,牙齿吸收影响了 423 颗牙齿中的 1.4%(6/423),这种疾病以前没有在美洲虎中记录过。其他异常包括在 33.3%(5/15)的美洲虎中放射学上发现的金属异物(枪击)和在 9.1%(1/11)接受咬合评估的美洲虎中发现的非创伤性咬合不正。在圈养美洲虎中发现的大部分口腔病理学可能是由于捕获和/或与圈养相关的行为引起的,例如口腔周围的枪击、颅牙(犬齿和门齿)骨折以及与犬齿咬笼相符的磨损。建议对有口腔疼痛临床症状的美洲虎以及进行常规系统评估的美洲虎进行麻醉口腔检查,包括全口口腔内放射检查、牙周探查和图表记录。
