摘要
区域性牙发育不良(ROD)是一种局部乳恒牙发育异常,具有独特的鬼影样影像学表现,临床表现为牙齿萌出延迟、形态异常,牙周软组织反复肿胀等,对患者影响深远.本文报告1例因面部肿胀就诊的2岁患儿,通过病史、口腔检查、影像学及组织学检查,结合文献回顾,分析其病理特征、可能发病机制、多学科诊治特点,帮助临床医师深入了解这类罕见病,为进一步研究提供临床样本.
Abstract
Regional odontodysplasia(ROD)is a localized developmental anomaly involving deciduous and perma-nent dentition,with a significant impact on patients.The affected teeth display unique ghost-like radiological characteris-tics,clinically manifesting as delayed tooth eruption,abnormal tooth morphology,and recurrent swelling of gingiva.In this paper,we report a case of a 2-year-old patient with ROD whose chief complaint was facial cellulitis.We analyze the medical history,clinical examination,radiographic findings,and histologic findings,and review the pathological fea-tures,pathogenesis,multidisciplinary diagnosis,and treatment of ROD.This rare case,which offers clinical samples for its further study,can provide a deeper study of ROD.
