ABSTRACT 

Background: The determination of sex from human skeletal material is of fundamental importance for any forensic investigator. Sexual dimorphism refers to the differences in size, stature, and appearance between male and female. The mandible is considered suitable for study as it is the most durable bone of the face and has got sexual dimorphism. So the present study was done to determine the usefulness of mandible as an aid in sex determination.

Materials and methods: The present study was done on 47 mandibles (22 males and 25 females) from department of Anatomy, All India Institute of Medical Sciences, Bhubaneswar, to find out the most reliable metric parameter in mandible to determine the sex of an unidentified individual.

Results: In our study we found that the angle of the mandible, bigonial breadth and bicondylar breadth were the most reliable parameters. The mean value of angle of the mandible, bigonial and bicondylar breadth in male was 126.73±2.71, 94.69±2.46, 111.20±5.73mm respectively and in female135.42±2.58, 88.27±7.84, 107.89±4.03mm with p value 0.0001, 0.0006 and 0.0287 respectively.

Conclusion: This study may help in identifying the sex of mutilated and unidentified bodies when combined with some other criteria used for sex determination.

Keywords: Angle of mandible, bigonial breadth, bicondylar breadth, sexual dimorphism.
