Introduction: Sex determination is a subdivision of forensic odontology and it is very important especially when information relating to the deceased is unavailable.
Aim and Objective: To determine canine, premolar and molar indices in upper and lower arch and to evaluate the accuracy of canine, premolar and molar indices in determining sex.
Materials and Method: This study includes 28 patients of both sexes, age range between 18-45 years. Upper and lower impressions were made using alginate and the obtained casts were subjected to determine the canine, premolar and molar indices.
Results: In lower arch, there is a high significant gender difference at 1% level for mesio-distal width of canine and premolar index and 5% significance for molar index and premolar arch-width.
Conclusion: This study shows >70% of accuracy in sex determination using mandibular premolar index, premolar arch width and mandibular mesio-distal width of canine.
