Dentinogenesis imperfecta (DI) is the result of a dominant genetic defect and affects both the deciduous and permanent dentitions. It is characterized by opalescent teeth composed of irregularly formed and undemineralized dentin which obliterates pulp chamber and root canal. DI can appear as a separate disorder or with osteogenesis imperfecta (OI). The teeth with DI show a grayish-blue to brown hue with dislodged enamel, dysplastic dentine with irregular dentinal tubules and interglobular dentine, short roots and pulpal obliteration, which all may lead to rapid and extensive attrition which require adequate crown reconstruction. The aim of this study was to show a reconstruction of frontal teeth in upper jaw with direct composite veneers in young adult patient with DI.
牙本质发育不全（DI）是一种显性遗传缺陷的结果，会影响乳牙列和恒牙列。其特征是牙齿呈乳光色，由不规则形成且未脱矿的牙本质组成，这些牙本质会使牙髓腔和根管闭塞。DI 可单独出现，也可与成骨不全（OI）同时出现。患有 DI 的牙齿呈现出灰蓝色至棕色的色调，伴有釉质脱落、牙本质发育异常，牙本质小管不规则且有球间牙本质，牙根短且牙髓闭塞，所有这些都可能导致快速且广泛的磨损，需要进行适当的冠修复。本研究的目的是展示在一名患有 DI 的年轻成年患者中，用上颌前牙直接复合贴面进行修复的情况。
