The present study was undertaken to determine the precise location of the mental and mandibular foramina and the surrounding anatomic landmarks. Measurements were made on both right and left sides of each of 34 dried young Turkish adult (30-40 years old) human male mandibles. The mandibles were moderately robust and were from dentulous subjects. The results obtained in the study showed that the distance of the mandibular foramen to the angle of the anterior ramus were 16.9 mm on the right and 16.78 mm on the left. The distance to the posterior side of the ramus was 14.09 mm on the right, and 14.37 mm on the left. The narrowest anteroposterior diameters were 32.8 mm on the right and 32.05 mm on the lot. The mandibular foramen is 0.5 mm posterior to the centre of the ramus on the right and 0.75 mm on the left. The distance of the lowest point of mandibular notch to the foramen was 22.37 mm on the right and 22.17 mm on the left. The distance from the mandibular foramen to the inferior border of the ramus in the mid position of the ramus was 30.97 mm on the right and 29.75 mm on the left. The average angle of the mandible (gonial angle) was 120.17degrees on both sides. The distance of the mental foramen to the inferior border of the mandible was 14.61 mm and 14.29 mm on the right and left, respectively. Its distance to the superior border was 13.62 mm on the right and 14.62 mm on the left. The horizontal dimensions of the mental foramen was 2.93 mm on the right, 3.14 mm on the left and its vertical dimension was 2.38 mm on the right and 2.64 mm on the left. The mental foramen was located below the root of the second premolar in 21 bones (61.76%) on the right and 17 bones (50%) on the left while in the remaining mandibles, the foramen was present between the roots of the first and second premolars in 13 bones (38.2%) on the right and in 17 (50%) on the left. The average angle of the mental foramen was 96.82degrees.
