To characterize the clinical, diagnostic imaging, and histologic features with description of treatment outcome of periapical cysts in dogs.
Ten client-owned dogs diagnosed with periapical cysts biopsied between July 1, 2000 and June 30, 2020.
Medical records of the Matthew J. Ryan Veterinary Hospital of the University of Pennsylvania were retrospectively searched to identify dogs that had surgical biopsy specimens of cavitary lesions diagnosed as odontogenic cysts and that met additional inclusion criteria. Complete medical records were reviewed.
Range age and body weight of affected dogs were 2.5-12.1 years and 4.3-38.4 kg (9.5-84.7 lb), respectively. All periapical cysts were affecting the incisive bone and/or the maxilla. Nine dogs presented with a fluctuant swelling of the oral mucosa and gingiva; one dog without clinical swelling presented with a history of difficulty breathing. All cysts originated from a non-vital tooth with a structural defect (wear or fracture without pulp exposure) and/or intrinsic staining. Extraction of the associated non-vital teeth, enucleation of the cysts, and curettage of the surgical sites resulted in resolution of the clinical signs.
The findings indicate that periapical cysts are associated with a non-vital tooth without pulp exposure. Complete evaluation of the clinical, diagnostic imaging, and histologic features of the lesion in affected dogs is necessary to differentiate periapical cysts from other odontogenic cysts and tumors.
描述犬根尖囊肿的临床、诊断影像学和组织学特征，并阐述其治疗结果。
2000年7月1日至2020年6月30日期间接受活检确诊为根尖囊肿的10只客户拥有的犬。
对宾夕法尼亚大学马修·J·瑞安兽医院的病历进行回顾性检索，以确定有诊断为牙源性囊肿的空洞性病变手术活检标本且符合其他纳入标准的犬。查阅完整的病历。
患犬的年龄范围和体重分别为2.5 - 12.1岁和4.3 - 38.4千克（9.5 - 84.7磅）。所有根尖囊肿均累及切牙骨和/或上颌骨。9只犬出现口腔黏膜和牙龈波动性肿胀；1只无临床肿胀的犬有呼吸困难病史。所有囊肿均起源于一颗有结构缺陷（磨损或骨折但牙髓未暴露）和/或内部染色的无活力牙齿。拔除相关的无活力牙齿、囊肿摘除术以及手术部位刮治术使临床症状得到缓解。
研究结果表明根尖囊肿与牙髓未暴露的无活力牙齿有关。对患犬病变的临床、诊断影像学和组织学特征进行全面评估，对于将根尖囊肿与其他牙源性囊肿和肿瘤区分开来很有必要。
