釉质发育不全(amelogenesis imperfecta,AI)是一组影响釉质发育的遗传性疾病,由于釉质形成时造釉器的某些功能障碍,导致釉质在厚度、结构和组织上的改变[1]。临床可分为3型[2]:釉质发育不良型(hypoplastic AI,HPAI),釉质矿化不良型(hypocalcified AI,HCAI)和釉质未成熟型(hypomaturation AI,HMAI)。AI以牙色改变和釉质缺损为主要表现,严重者可伴有颞下颌关节紊乱病(temporomandibular joint disorders,~TMD)等。笔者在临床中遇到1例全口乳牙、恒牙严重AI伴~TMD病例,现报道如下。1病例摘要患者女,22岁。主诉:牙齿不美观,颞下颌关节疼痛。2014-03-20就诊于南昌大学附属口腔医
Amelogenesis imperfecta (AI) is a group of hereditary diseases that affect the development of enamel. Due to some dysfunction of enamel formation during enamel formation, enamel changes in thickness, structure and organization [1]. Clinically, it can be divided into three types [2]: hypoplastic AI (HPAI), enamel hypocalcified AI (HCAI) and hypomaturation AI (HMAI). Alzheimer’s disease and enamel defects as the main performance, severe cases may be associated with temporomandibular joint disorders (~ TMD) and so on. I encountered in the clinical case of complete deciduous teeth, severe permanent AI with ~ TMD cases are reported below. 1 case summary Female patient, 22 years old. Chief complaint: teeth is not good, temporomandibular joint pain. 2014-03-20 Visiting stomatology affiliated to Nanchang University
