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.
