Background: Human teeth of both primary and permanent dentitions sometimes shows developmental malformation which results in alteration of their size, shape and structure and especially with the crown either in the form of anomalous cusps or an increase in the number of cusp. A protostylid is a supernumerary or accessory cusp found on the molars on the mesial half of the buccal surface. Case discussion: This case report presents a rare finding of protostylid on the buccal surface of the permanent left second molar tooth in a 12 year old female patient. There was no similar finding seen on the other teeth and in other members of the family. Conclusion: The dental polymorphisms described in this case report is some of the rarest and unique forms of the human dentition. Thus, the reporting and preservation of these structures can be important from the perspective of forensic odontology. Clinical significance: Though this may not pose significant problem in most instances but its finding is of very much significant interest from the perspective of forensic dentistry.
