Introduction: The mandibular foramen portrays a cardinal anatomical landmark for the repositioning of the mandible during sag ittal split osteotomies performed to correct structural deformities like prognathism and retrognathia. These landmarks are crucial for adequate anaesthesia while performing the inferior alveolar nerve block. The mental foramen is an important landmark in carrying out invasive procedures like a mental or incisive nerve block. Objectives: To observe the shape, position and distance from various mandibular anatomical landmarks of the mental foramen, and the length of the mandibular canal. Methods: This cross-sectional study included 41 human mandibles, which were available in the department. After applying the inclusion and exclusion criteria, thirty dried adult human mandibles with an intact alveolar margin of unknown gender were used. Results: The shape of mental foramen was found oval in 80 per cent and circular in 20 per cent of the mandible irrespective of side. The mean distance of mental foramen from symphysis menti, posterior border of the ramus, alveolar crest, and lower border of the body of mandible was found 24.38__ampersandsignplusmn;1.91 mm, 63.62__ampersandsignplusmn;2.5 mm, 13.15__ampersandsignplusmn;1.64 mm, and 14.15__ampersandsignplusmn;1.58 mm on the right side. Whereas on the left side mean distance was 24.01__ampersandsignplusmn;1.86 mm, 63.49__ampersandsignplusmn;2.22 mm, 13.23__ampersandsignplusmn;1.65 mm, and 14.06__ampersandsignplusmn;1.69 mm, re spectively, from the above parameters. Conclusions: Mental foramen__ampersandsignrsquo;s usual position was below the second premolar. Since it is not possible to palpate the MF clini cally, it is necessary to know its accurate place. This will reduce the chances of inadvertent injury during invasive dental proce dures like various pre-prosthetic operations and implant insertion.
