Regional odontodysplasia is an uncommon developmental anomaly affecting a localized area of dentition, with distinctive clinical, radiographic, and histological findings. This article reviews a case of a 14-year-old female who reported with unerupted maxillary anterior teeth. This case was rare in that it involved maxillary dentition with unerupted maxillary anterior teeth on the right side, but the left central incisor was missing. The molars on the right side were showing some amount of abnormality. Radiographically, the affected teeth had a 'ghostly' appearance, showing a marked reduction in radiodensity. Both enamel and dentin appeared to be very thin, the pulp chamber was exceedingly large, and the roots were short with wide open apices. All the characteristics were consistent with the diagnosis of regional odontodysplasia. The care and treatment of this patient required a multidisciplinary approach. The unerupted maxillary anterior teeth were surgically removed, following which temporary prosthetic restoration was provided to improve esthetics and to restore the function.
局部牙发育异常是一种罕见的发育异常,影响牙列的局部区域,具有独特的临床、影像学和组织学表现。本文回顾了一例14岁女性患者,其报告上颌前牙未萌出。该病例罕见之处在于,它累及上颌牙列,右侧上颌前牙未萌出,但左侧中切牙缺失。右侧磨牙有一定程度的异常。影像学上,患牙呈“幽灵”样外观,表现为放射密度明显降低。釉质和牙本质似乎都非常薄,髓腔极大,牙根短且根尖孔敞开。所有特征均符合局部牙发育异常的诊断。该患者的护理和治疗需要多学科方法。手术拔除未萌出的上颌前牙,随后进行临时修复,以改善美观并恢复功能。
