A novel presentation of a supplemental premolar tooth with dens invaginatus and dens evaginatus and role of the CBCT in diagnosis

Abstract

Dens evaginatus(DE) and dens invaginatus(DI) are rare developmental dental abnormalities. Though these variations in odontogenesis have been individually observed and reported, no case of concomitance of DE and DI in a supplemental premolar have been reported in the literature. For the clinicians, it is important to recognize these anomalies and to be knowledgeable about their management. The aims of this paper are to report the radiographic and tomographic findings of a novel case of DE with type II and IIIDI and to discuss the importance of early identification and efficient management of these anomalies.
