Abstrakt:	Introduction: The variable relation and clinical significance of mandibular foramen (MF) and Lingula with inferior alveolar neurovascular bundle (IANB) is important for dental surgeons. Knowing the landmarks on the ramus of the mandible is of paramount importance to perform the surgery without causing damage to the neurovascular bundle. Materials and Methods: This study was conducted on 85 dry adult mandibles of unknown sex and age. The distances were measured from the anatomical reference points (anti- Lingula , Lingula and MF) using digital callipers. Results: The distance from the anti- Lingula to the anterior border of the ramus (A) was significantly longer on the right side (14.91 mm) than on the left side (14.5 mm). There was a significant difference in mean distances between the anti- Lingula and MF of both the sides ( P ≤ 0.005). No significant difference was noted in the distances between the Lingula and the Anti- Lingula , observed for the posterior (B, P = 0.75) and the inferior margin of the mandible (D, P = 0.54). However we found correlation of vertical distances of anti-Lingula with Lingula and MF exhibited moderate positive correlation. Discussion: The IANB is prone to damage during mandibular surgery. Using anti- Lingula alone as a reference point is not guaranteed, but it is still an important anatomical landmark for the surgeon to operate. Competing Interests: There are no conflicts of interest.
