This report describes a rare case of congenital oligodontia of the deciduous teeth and anodontia of the permanent teeth in a cat. According to cat's veterinarian, the patient had only two deciduous upper canines and no permanent teeth had ever erupted. Post-mortem evaluation showed a complete absence of teeth in the oral cavity and inflammatory lesions were not found on the gums. Histopathological analysis of serial sections of maxilla and mandible revealed absence of odontogenic epithelium, inflammatory cells and odontoclastic resorptive lesions. Diagnosis was confirmed after both the establishment that there were no remaining dental structures and the exclusion of other relevant diseases that lead to tooth loss, such as periodontal disease, renal fibrous osteodystrophy, odontoclastic resorptive lesions, ectodermal dysplasia and trauma.
本报告描述了一例罕见的猫乳牙先天性少牙症和恒牙无牙症病例。据猫的兽医称，该患者仅有两颗乳上门牙，且恒牙从未萌出。尸检评估显示口腔内完全无牙，牙龈未发现炎症病变。对上颌骨和下颌骨连续切片进行组织病理学分析，结果显示无牙源性上皮、炎症细胞和破牙细胞吸收性病变。在确定不存在剩余牙结构并排除其他导致牙齿脱落的相关疾病（如牙周病、肾性纤维性骨营养不良、破牙细胞吸收性病变、外胚层发育不良和创伤）后，确诊成立。
