Abstract

A dental cusp is a prominence on the crown of the tooth and is present normally on posterior teeth. This study was carried out to determine the frequency of different accessory cusps, their sites and presence of unilateral/bilateral cusps among males and females of three distinct ethnic populations of North India-Brahmin, Rajput and Muslim with reverence to their forensic utility. The frequency analysis revealed that the male had higher presence of accessory cusps than the females, while the communities showed minor variation in the accessory cusps. The Brahmins had the most bilateral cusps (15.3%) followed by Rajputs (14.4%) and Muslims (8.6%) the least. Further, the Carabelli's cusps were found with highest frequency than the talon cusps which are the rarest type of cusps in these communities. However, the findings suggest that the accessory dental cusps may provide the clue the identity of the individuals in the absence of any other physiognomic characteristics.
