Abstract

The author measured the distance from mental foramen to the occusal plane and classified the positional frequency of mental foramen to the tooth site using topography. The results were obtained as follow; 1. Of 964 mental foramen taken, the common site was in 2nd premolar region showing 64.08 per cent in right and 57.17 per cent in left site. 2. The average distance from occlusal plane to the upper border of premolar region was 23.20㎜. and lower border was 25.07㎜. 3. The positional variation of mental foramen was 4.77 per cent were located above the apex of the nearest tooth, and 50.42 per cent were located at the apex of the nearest tooth and 44.81 per cent were located below the apex of the nearest tooth.
