ABSTRACT
Background. As the mental foramen (MF) is an important landmark to facilitate surgical, local anesthetic, and other invasive procedures, the present study was aimed to elucidate its morphological features and morphometric parameters with reference to surrounding landmarks. Material and Method. 105 dry adult human mandibles of unknown sex were observed for position, shape, and number of mental foramina. Their size was measured using a digital vernier caliper and statistically analyzed by mean and standard deviations (SD). Results. In most cases (74.3%), the MF was oval in shape and situated on the longitudinal axis of the 2nd premolar tooth (61% on right side and 59.1% on left side). The mean distance for the right and left sides was measured from various landmarks. Conclusion. Prior knowledge of mental foramen variations helps surgeons in planning surgery in that region to avoid nerve damage and also enable effective mental nerve block anesthesia.

Mentions: The most common position was on the longitudinal axis of second premolar (position IV) (Figure 3) followed by positions III (Figure 4), V (Figure 5), II (Figure 6), and VI (Figure 7). The MF was not observed in position I in any mandible. Results are presented in Table 1. To locate the MF and to measure its size, various parameters were considered and the results are presented in Tables 2 and 3.
