Dentinal Dysplasia Type I is a rare condition affecting the deciduous and permanent dentitions, in which the teeth present with short roots and considerably reduced or obliterated pulp spaces. These features were observed on the radiographs of a patient referred for orthodontic assessment, and an investigation of other members of the family revealed that the father and two siblings were also affected. There were variations in the lengths of the roots in those affected, and thus a subclassification of the dysplasia is proposed.
I型牙本质发育异常是一种影响乳牙和恒牙列的罕见病症,患病牙齿表现为牙根短且牙髓腔显著缩小或消失。在一名因正畸评估前来就诊患者的X光片上观察到了这些特征,对该患者家族其他成员的调查显示,其父亲和两个兄弟姐妹也患有此病。患病者牙根长度存在差异,因此提出了该发育异常的一个亚分类。
