摘要/Abstract

摘要： 牙本质发育不良I型（dentin dysplasia type I,DD-I）是一种伴有牙本质形成障碍、可遗传的罕见病。其特征是牙冠正常,但牙根发育异常,出现短、钝化和畸形的牙根;在患者年轻时即出现牙松动,可伴牙槽脓肿;影像学上表现为闭塞的牙髓腔。典型的DD-I是常染色体显性遗传,家系中患者常很早即出现多颗牙丧失,有的30多岁即可表现为无牙颌。本文报告了一例DD-I病例,通过总结其临床表现、影像学及组织学特点以及相关治疗,以期为DD-I临床诊治提供指导。

Abstract: Dentin dysplasia type I (DD-I) is a rare hereditary disturbance in dentin formation. It is characterized by the normal tooth crown but abnormal root development, which is manifested by the presence of short, blunted, and malformed roots; tooth loosening with alveolar abscess occurs at a young age in patients; imaging examination shows occluded pulp cavities. Typical dentin dysplasia type I is autosomal dominant. Patients often loss multiple teeth, and may become edentulous by their 30s. Clinical treatment is challenging. In this paper, a DD-I case is reported, summarizing its clinical manifestations, imaging and histological features, and related treatments in order to provide guidance for the clinical diagnosis and treatment of DD-I.

Key words: Dentin dysplasia type I, Autosomal dominant inheritance, Clinical features, Implant treatment
