Purpose: As it is part of the mandible and a vital transmission structure, it is crucial to explore and examine the Mental Foramen (MF) in various populations and races. Material and Method: Orthopantamograms were examined, and the MF was identified. The MF was traced on transparent paper. A line was drawn from the apex of the 1st premolar to the 2nd premolar using a ruler, and it formed a vertical plane. Two horizontal planes were drawn on the longitudinal axis of the 1st premolar and 2nd premolar by using a ruler. Result: The horizontal plane in females was as follows: in position 1, (R=5.14%), (L=8.08%); in position 2, (R=51.4%), (L=51.4%); in position 3, (R=31.23%), (L=31.6%); and in position 4, (R=13.23%), (L=8.82%). The location of the MF in the vertical plane in females was above (R =1.47%), (L=2.2%), at (R=8.08), (L=8.82%), and below (R=90.4%), (L=88.9%). The location of the MF in the horizontal plane in males was as follows: in position 1, (R=1.62%), (L=3.25%); in position 2, (R=56.9%), (L=56.9%); in position 3, (R=27.6%), (L=30.8%); and in position 4, (R=13.82%), (L= 8.94%). The location of the MF in the vertical plane in males was above (R=2.43%), (L=1.62%), at (R=15.4%), (L=16.2%), and below (R=82.11%), (L=82.11%). Conclusion: The most common location of the MF in males in the horizontal plane was position 2, and in the vertical plane, it was below the vertical plane.
