Dens evaginatus (DE) and dens invaginatus (DI) are rare developmental anomalies of tooth formation. These variations in odontogenesis have been individually observed and reported in the literature. This report describes the radiographic appearance and management of a 16-year-old boy who came to the clinic with a rare occurrence of both DE and DI in the same tooth and examines the criteria used in identifying and classifying such anomalies. This report also discusses the importance of early identification and efficient management of dental anomalies, which can prevent irreversible pulpal pathology that requires endodontic therapy or tooth loss.
牙外突(DE)和牙内陷(DI)是牙齿形成过程中罕见的发育异常。这些牙发育异常已在文献中被分别观察和报道。本报告描述了一名16岁男孩的影像学表现及治疗情况,该男孩因同一颗牙齿罕见地同时出现DE和DI前来就诊,并探讨了用于识别和分类此类异常的标准。本报告还讨论了早期识别和有效治疗牙齿异常的重要性,这可以预防需要进行牙髓治疗或导致牙齿缺失的不可逆牙髓病变。
