A rare case of dens evaginatus and dens invaginatus in the same tooth, with a review of treatment options.

ABSTRACT

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.
