Mandibular Second Molar Protostylid: A Rare Case Report

Abstract

Aim: The aim of this case report is to present a rare finding of protostylid on the mandibular second molar.
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
