Introduction: Mandibular foramen has its clinical importance in giving inferior alveolar nerve block very
commonly give n in various dental procedures like removal of third molar tooth, Dental pain, Dentoalveolar
trauma, Dry socket, Periapical abscess and in painful procedure on mandible or lower lip/chin. So it is very
essential to know the anatomy of mandible particularly mandibular foramen which is situated just above
the centre of the medial surface of the ramus of the mandibl e. Mandibular foramen gives passage to
inferior nerve and vessels to sup ply the teeth of lower jaw. Mandibular foramen provides an important
anatomical land mark. The inferior nerve block is the commonest local anaesthetic technique in clinical
practice in dental procedures. There are chances of failure of Inferior alveolar nerve block failure due to its
variations in position of. So it requires detailed anatomical study of mandibular foramen. This study aims
to determine the exact position of mandibular foramen in relation to various landmark on mandible. We
have studied dry adult human mandibles of people of Gujarat region.
Materials and Methods: The material for the present study includes 100 adult dry human mandibles of
unknown sex. These were collected from Govt. Medical College, Bhavnagar. All measurements were
recorded using a sliding vernier caliper. Measurements were taken using below mentioned bony landmarks
on the mandible.
Results: The study shows mean distance of mandibular foramen to anterior border of ramus
17.052.70mm on right side and 17.353.00mm on left side, to posterior border of ramus was
10.412.13mm on right side and 9.722.06 mm on left side, to mandibular notch 21.502.81mm on
right side and 21.883.31 mm on left side, base of man dible or inferior border was 22.203.28 mm on
right side and 25.304.2mm on left side.
Conclusion: The present study gives knowledge of the position of mandibular foramen and provides useful
information for successful local anaesthesia (inferior alveolar nerve block) during various dental procedures
and surgeries.
