Double dens evaginatus on permanent maxillary first molar: A case report of this rare occurrence

Abstract

Dens evaginatus (DE) is a developmental aberration of a tooth resulting in the formation of an accessory cusp. This uncommon anomaly projects above the adjacent tooth surface, exhibiting enamel covering a dentinal core that usually contains pulp tissue. DE usually occurs in mandibular premolars. The most comprehensive grouping of DE on premolars has been done by Schulze (1987). DE may pose various dental problems to clinicians. This case report describes a very rare case of double DE on the permanent maxillary first molar of 14-year-old boy. Till date, there is no such documented case. The deep caries of this tooth was restored.
