title: Co-existence of two dens invaginations with one dens evagination in a maxillary lateral incisor: a case report.
abstract: A case with two simultaneous dens invaginations (DIs) and one dens evagination (DE) in a permanent maxillary lateral incisor is reported for the first time in a 21-year-old girl. DE known as talon cusp of the anterior teeth is a rare entity and its co-existence with DI has been reported scarcely in the literature. Simultaneous occurrence of two DIs with one DE has not been reported elsewhere. Undoubtedly, familiarity with the internal anatomy of such a rare condition can help prevent pulpal disease while performing restorative procedures.
