Multiple dental developmental abnormalities (e.g., dental impaction, partial eruption, oligodontia, enamel hypoplasia, and dentin hypoplasia) in a 10-month-old, female, Tanzanian tropical mixed-breed puppy are reported. Various permanent teeth were involved. These included impacted mandibular canine and first and third premolar teeth; a partially erupted maxillary canine tooth; oligodontia of a mandibular fourth premolar tooth; enamel hypoplasia of the maxillary and mandibular canine teeth, incisors, and premolars; and dentin hypoplasia of the maxillary incisors, maxillary premolars, and mandibular premolars. The puppy had clinical canine distemper at the age of two months and had no history of any other systemic nor generalized infection prior to the time when the dental abnormalities were observed.
据报道,一只10个月大的坦桑尼亚热带混种雌性幼犬出现了多种牙齿发育异常(如牙齿阻生、部分萌出、少牙症、釉质发育不全和牙本质发育不全)。多颗恒牙受累。其中包括下颌尖牙、第一和第三前磨牙阻生;上颌尖牙部分萌出;下颌第四前磨牙少牙症;上颌和下颌尖牙、切牙和前磨牙釉质发育不全;以及上颌切牙、上颌前磨牙和下颌前磨牙牙本质发育不全。这只幼犬在两个月大时患有临床犬瘟热,在观察到牙齿异常之前没有任何其他全身性或全身性感染的病史。
