Abstract

Human dentition either primary or permanent exhibits a number of developmental morphological variations ranging from mild alterations in tooth shape to well developed supernumerary cusp. These genetic malformations may present as an isolated finding or as a part of a syndrome. A protostylid is an uncommon anomaly which presents as a supernumerary or accessory cusp located on the mesial half of the buccal surface on the maxillary or mandibular molars which seldom pose problems to the patient. As its prevalence varies with ethnic diversity, it is a frequent object for anthropological studies. A 31 year old Pakistani female presented with a complaint of pain in right mandibular quadrant. Complete intraoral examination revealed a supernumerary cusp on the right permanent maxillary first molar as an incidental finding. No syndromic association was found.
