Dens evaginatus in association with supernumerary teeth: Report of a case

Abstract

Dens evaginatus is an uncommon developmental anomaly that appears as a tubercle or an accessory cusp projecting from the occlusal surface of the affected tooth. The anomaly most commonly affects the premolars, and the mandibular premolars are five times more frequently affected than the maxillary premolars. Dens evaginatus occurs almost exclusively in people of mongoloid origin. Isolated cases of dens evaginatus have also been documented in the Caucasian population. This article describes a case of dens evaginatus on the maxillary left first premolar affecting a Bengali boy. The child also exhibited two mesiodens and shovel-shaped maxillary incisors. Both dens evaginatus and supernumerary teeth are clinically significant anomalies. Early diagnosis of dental anomalies helps in selecting the correct treatment plan and minimizes further complications.
