Sex determination is a subdivision of forensic odontology and it is very important especially when information relating to the deceased is unavailable.
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.
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.
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.
This study shows >70% of accuracy in sex determination using mandibular premolar index, premolar arch width and mandibular mesio-distal width of canine.
