Objective: Identi ication is foremost to forensic investigators and this includes determining race, age and sex of individuals. This investigation is pointed toward deciding sex from detailed observation of the Mental Foramen (MF) by comparing the Upper Limit (UF-L) and Lower Limit of the foramen (LF-L) to the lower limit of mandible.

Methods: This retrospective study investigated a hundred and ten clear radiographs without any pathology of 55 males and 55 females, between 20-60 years.

Results: Statistically signi icant differences (p<0.05) were obtained in all measurements between gender with the obtained Mean and SD values of 14.63 ± 2.59 in males UF-L and 13.60 ± 2.57 in female UF-L, also 11.78 ± 2.41 and 10.58 ± 2.31 in males and females LF-L respectively. Signi icantly higher values were noticed in males, and this establishes differences between genders.

Conclusion: Conclusively, the exact position of MF in reference to mandible is an additional radiographic method to determine gender. Result obtained will be of relevance to anatomist, forensic anthropologists and maxillofacial surgeons.
