面部间隙感染为首发症状的区域性牙发育不良1例及文献回顾

Regional odontodysplasia with facial cellulitis:a case report and literature review

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。

Regional odontodysplasia(ROD) is a localized developmental anomaly involving deciduous and permanent dentition,with a significant impact on patients.The affected teeth display unique ghost-like radiological characteristics,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 features,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.
