区域性牙发育不良的研究进展

Research progress in regional odontodysplasia

区域性牙发育不良(ROD)是一种罕见的局部牙齿发育异常,临床典型症状为牙齿萌出异常,牙釉质和牙本质发育障碍,影像学表现为"鬼影牙"。ROD病因尚未明确,临床上应根据病例情况制订个性化诊疗方案,进行口腔多学科综合协作的序列治疗。本文详述了ROD的定义、病因、流行病学特点、临床表现、影像学表现、牙齿微观结构和治疗等,以期为临床诊疗提供参考。

Regional odontodysplasia(ROD)is a rare localized dental developmental anomaly.The typical clinical manifestations of ROD are abnormal tooth eruption,abnormal development of enamel and dentin.The radiographic characteristic is"ghost teeth".Its etiology still remains unknown.The care and treatment of a patient with ROD needs a multidisciplinary approach.And the treatment should be taken after the assessment of each individual case of ROD.This paper reviews the definition,etiology,epidemiological features,clinical manifestations,imaging features,dental microstructure and treatment strategies of ROD to provide reference for clinical diagnosis and treatment.
