Introduction: Mental foramen is the important anatomical landmark situated on the anterolateral surface of the body of the mandible. It transmits mental nerves and vessels. Aim of the present study is to provide the morphometric data of the mental foramen so as to provide the valuable information to the dental surgeon, maxillofacial surgeon and anaesthetists. Study was carried out on 100 dry adult mandibles of unknown sex. We found the shape of mental foramen was oval in 62% and round in 38% of mandibles. The mean transverse diameter was 3.11mm on right side and 3.18mm on left side. The mean vertical diameter was 2.53mm on right side and 2.56mm on left side. The mental foramen was situated below the apex of second premolar tooth in 73% on right side and 75% on left side. The distance between mental foramen and symphysis menti (D1) was 25.81±2.25mm on right side and 25.81±2.11mm on left side. The distance between mental foramen and alveolar border (D2) was 12.42±2.13mm on right side and on left side was 12.51±2.0mm. The distance between mental foramen and inferior border of body mandible (D3) was 12.39±1.25mm on right side and on left side it was 12.27±1.13mm. The distance between mental foramen and posterior border of ramus (D4) was 66.90±4.41mm on right side while on left side it was 65.90±7.96mm. There was no significant side difference either in position or the morphometry of mental foramen.
