Aim: Gender identification of unidentified skeletal remains is a challenging task for any forensic dentist. This study is intended to find a correlation between the analysis of mental foramen and the gender in New Delhi population which can be extrapolated.

Materials and Methods: One hundred orthopantomographs were selected in which the mental foramen was identified as separate type. Tangents were drawn to the superior and inferior borders of the mental foramen and perpendiculars were drawn from the tangents to the lower border of the mandible (S–B and I–B). Statistical analysis was done on the data obtained.

Results: The mean values of S–B and I–B were significantly greater in males than in females. The difference in distances of the right and left side mental foramina from the midline in both the males and females were non–significant.

Conclusion: The analysis of mental foramen can be used in gender determination as evidenced by this retrospective study on orthopantomographs.
