<i>Dens evaginatus</i> and <i>dens invaginatus</i> in a maxillary lateral incisor: Report of a rare occurrence and review of literature

Abstract

A case of dens evaginatus (DE) and dens invaginatus (DI) concurrently affecting the maxillary right permanent lateral incisor in a 25-year-old Hispanic male is reported. DE, referred to as Talon's cusp in the anterior teeth and Leong's premolar in the premolar teeth, is a relatively rare condition by itself. An association of DI with this rare anomaly within the same tooth has never been reported before although it has been known to occur within the same patient. Since it is known that DE may be composed of normal enamel and dentine, as well as varying amounts of pulpal tissue, care should be exercised while performing any aesthetic procedures to remove or recontour it.
