Abstract

Patellar fracture and dental anomaly syndrome (PADS) is a congenital bone disease of cats that is characterized by atraumatic bone fractures (most commonly the patella), the persistence of deciduous teeth, and impaction of permanent teeth. Jaw swelling due to osteomyelitis is often the reason that cats with PADS are presented for veterinary dental care. The clinical history, oral examination findings, dental radiological findings, and histopathology were evaluated for 13 cats with dental and skeletal pathology consistent with PADS, including 9 with osteomyelitis. Cats in this study were predominantly domestic shorthair (12 of 13 cats), and there was no apparent sex predilection. All cats had multiple persistent deciduous teeth and multiple impacted permanent teeth, although the number of persistent and impacted teeth varied. Osteomyelitis of the jaw typically occurred within the first 4 years of life. Osteomyelitis of the mandible was 4 times more common than osteomyelitis of the maxilla. Histologically, osteomyelitis was chronic, neutrophilic, and osteoproliferative. Necrotic bone was confirmed in 67% of osteomyelitis lesions. Histological evaluation of jaws without inflammation demonstrated abnormal amounts of unmodeled bone, abnormally dense bone, and retention of cartilage in the caudal mandible. Three cats in the study had mandibular distoclusion and 2 had concurrent paronychia. To obtain a favorable clinical outcome in PADS cats with jaw swelling, prompt and aggressive surgical treatment of osteomyelitis is required. Extraction of persistent deciduous teeth and impacted permanent teeth is recommended when there is associated periodontitis or osteomyelitis.

猫髌骨骨折和牙齿异常综合征(PADS)的口腔病理特征。
髌骨骨折和牙齿异常综合征(PADS)是一种猫的先天性骨病,其特征是无创性骨折(最常见的是髌骨)、乳牙持续存在和恒牙嵌塞。骨髓炎引起的颌骨肿胀通常是患有PADS的猫接受兽医牙科护理的原因。评估了13只牙齿和骨骼病理与PADS一致的猫的临床病史、口腔检查结果、牙齿放射学结果和组织病理学,其中9只患有骨髓炎。这项研究中的猫主要是家猫(13只猫中有12只),没有明显的性别偏好。所有猫都有多颗恒牙和多颗阻生恒牙,尽管恒牙和阻生恒齿的数量各不相同。颌骨骨髓炎通常发生在生命的最初4年内。下颌骨骨髓炎的发病率是上颌骨骨髓炎的4倍。组织学上,骨髓炎是慢性的、中性粒细胞性的和骨增殖性的。67%的骨髓炎病变中证实有坏死性骨。对没有炎症的颌骨的组织学评估显示,下颌骨尾部有异常数量的未成型骨、异常致密的骨和软骨保留。研究中有三只猫患有下颌distoclusion,两只同时患有甲沟炎。为了在患有颌骨肿胀的PADS猫中获得良好的临床结果,需要对骨髓炎进行及时和积极的手术治疗。当伴有牙周炎或骨髓炎时,建议拔除持续性乳牙和阻生恒牙。
