Background: The mental foramen (MF) is a bilateral opening localized on an anterior surface of the mandible. The present study was conducted to assess the variation in size of mental foramen in adult population with CBCT. Materials & Methods: The present study was conducted on 62 patients of both genders. A CBCT scan was performed in all patients using Planmica CBCT machine operating at 90 kVP, 12 mAs and with exposure time of 18 seconds. Vertical size of MF (V) was determined on the cross-sectional CBCT images and the horizontal size of MF (H) was assessed on axial scans. Results: Out of 62 mandibles, 32 were of males and 30 were of females. On left side, type I was seen in 18 males and 14 females, type II was 10 in males and 12 in females, type III was 4 in males and 4 in females. On right side, type I was in seen in 13 in males, 14 in females, type II in 14in males, 10 in females, type III in 5 in males and 6 in females. The difference in males and females was non – significant (P> 0.05). On left side, mean horizontal diameter in males was 4.3 mm and in females was 3.5 mm, vertical diameter in males was 3.6 mm and in females was 3.1 mm. On right side, mean horizontal diameter in males was 4.8 mm and in females was 3.9 mm, vertical diameter in males was 3.1 mm and in females was 2.7 mm. The difference was significant (P< 0.05). Conclusion: CBCT is useful in detection and assessing vertical and horizontal measurement of mental foramen in both genders. There was variation in both genders in both sides.
