Evaluation of sexual dimorphism using permanent maxillary first molar in Sri Ganganagar population

Abstract

Aim of Study: The aim is to evaluate existence of sexual dimorphism by variation in right and left permanent maxillary molars using buccolingual width (BLW) and mesio-distal width (MDW) measured intraorally and on study casts among Sri Ganganagar population. Materials and Methods: Fifty patients (25 males and 25 females) with 17–25 years of age were selected. Impressions of maxillary arch were taken and the BLW and MDW were measured using digital Vernier calipers on study casts and intraorally. Results: Highly significant correlation was found between MDW and BLW of both the maxillary permanent first molars for both genders (P < 0.05) intraorally. The MDW and BLW on study cast of both sides in both gender were more on left side in males while on right side in females. Conclusion: Left maxillary permanent first molar showed minimum mean difference of measurements on study cast and introrally than right, thus better predictor for gender dimorphism in forensics.
