Oral disease involving teeth is a common cause of morbidity in aardvarks () under managed care. Cases can be challenging due to the species' unique skull and dental anatomy and limited veterinary literature. A retrospective evaluation was performed on dental examinations in nine aardvarks housed at a single zoological institution in the United States between 1995 and 2021. The prevalence of dental disease in this population was 88%, with most cases categorized as mild (4/8). Clinical signs were only seen in three cases. Facial swelling prior to surgery was the most common clinical sign (3/8). Dental pathology was more common in the mandibular teeth (27/38) compared to the maxillary teeth (11/38). Dental abnormalities found upon intraoral examination included the presence of dental points (7/8), crown elongation (3/8), purulent material within the oral cavity (4/8), loose teeth (2/8), periodontal pockets (2/8), and oronasal fistula (1/8). Three patients required dental extractions with a lateral buccostomy approach. Diagnostic imaging was performed in most cases (7/8), with two cases undergoing cone-beam computed tomography (CBCT) to characterize dental pathology that was difficult to fully evaluate with standard radiography. Tomographic findings are described in both cases. CBCT was found to be a helpful tool for diagnosing and characterizing dental disease in aardvarks.
在管理式医疗下,涉及牙齿的口腔疾病是食蚁兽发病的常见原因。由于该物种独特的头骨和牙齿解剖结构以及有限的兽医文献,病例可能具有挑战性。对1995年至2021年期间饲养在美国一家动物园机构的9只食蚁兽的牙齿检查进行了回顾性评估。该群体中牙齿疾病的患病率为88%,大多数病例分类为轻度(4/8)。仅在3例中出现临床症状。手术前面部肿胀是最常见的临床症状(3/8)。与上颌牙齿(11/38)相比,下颌牙齿的牙病更常见(27/38)。口腔检查发现的牙齿异常包括牙尖(7/8)、牙冠延长(3/8)、口腔内有脓性物质(4/8)、牙齿松动(2/8)、牙周袋(2/8)和口鼻瘘(1/8)。3例患者需要采用外侧颊部造口术进行拔牙。大多数病例(7/8)进行了诊断性成像,2例患者接受了锥形束计算机断层扫描(CBCT)以确定用标准放射照相难以充分评估的牙齿病变。描述了两例的断层扫描结果。发现CBCT是诊断和确定食蚁兽牙齿疾病的有用工具。
