Dens evaginatus on a permanent mandibular molar-report of a first case

Dens evaginatus is a developmental anomaly in form of an accessory cusp. It arises during morpho differentiation stage due to abnormal proliferation of the inner enamel epithelium into the stellate reticulum of the enamel organ. Though mandibular premolars are most commonly affected teeth, there are case reports of dens evaginatus of maxillary molars. However, dens evaginatus of a mandibular molar has not been reported till date to best of our knowledge. Thus, this case report adds a rare form of presentation of dens evaginatus to the existing literature.
