UNILATERAL PROTOSTYLID ON BUCCAL SURFACE OF PERMANENT MAXILLARY FIRST MOLAR: A RARE FINDING

Ghazala Hassan, Sarah Ghafoor.




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 congenital 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 maxillay 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. This is significant because no data is available regarding such anthropological landmark in Pakistani population.

Key words: Extra cusp; maxillary molar; morphological variations; protostylid; parastyle.
