Introduction: Mandibular foramen is an opening on the medial surface of the ramus of mandible, through this inferior alveolar nerve and vessels passes.
Aim: To determine morphology and morphometry of mandibular foramen of Central Indian population.
Material & Methods: 100 mandibles 53 male and 47 female dry dentulus, without deformities were examined for position, shape of mandibular foramen.
Results: The vertical distance between MDF and mandibular notch was 20.06 mm and 20.55 mm on left and right sides in male, 19.45 mm and 19.81 mm on left and right sides in female. The horizontal distance between the MDF and anterior border of ramus was 16.80 mm and 17.10 mm on left and right sides in male, 15.74 mm, and 15.91 mm on left and right sides in females. Distance between MDF and posterior border was 13.56 mm and 13.15 mm on left and right sides in male and 11.82 mm and 11.43 mm on left and right sides in females. Distance between MDF and third molar tooth 23.08 mm and 23.34 mm on left and right side in male and 22.51 mm and 22.38 mm on left and right side in females. The distance between MDF and mandibular base 25.93 mm and 25.78 mm on left and right side in males and 23.11 mm and 23.02 mm on left and right side in females.
Conclusion: Most common shape of the mandibular foramen is observed ‘round’ and the most common position of the mandibular foramen on medial side of the ramus of the mandible is upper and posterior quadrant and observed 15% male and12% females have accessory mandibular foramen. which will help for effective management, better clinicalresults, and prognosis. Comparison from other studies shows that geographical, genetic, and dietary variations does exist and hence knowing its position in native population is essential as it plays a crucial role in success of “pain-less” and “patient friendly” surgical procedures.
