Abstract

Background: Mental foramen is a small foramen situated in anterolateral aspect of the body of the mandible. Normally, mental foramen is located below the interval between the premolars. It transmits mental nerve, artery and vein. Mental nerve is a branch of inferior alveolar nerve which supplies sensation to lower lip and the labial mucosa and lower canines and premolars. The most useful injection for anaesthetizing the mandibular teeth is the inferior alveolar nerve block. To anaesthetize the anterior teeth, including the premolars and canines, it is possible to avoid giving inferior alveolar nerve block by injecting anesthetic solution adjacent to the mental foramen.
Materials and Methods: Totally 300 mandibles were used for this study, from different medical teaching Institutes. The following measurements were measured and recorded. The results were expressed in the form of Mean ±SD.
Results: The shape of foramen was oval in 72%. The knowledge of mental foramen is very important for blockage of mental nerve. The location of mental foramen was found 78.65% in line with the longitudinal axis of the second molar teeth, 13.52% was present in between first and second molar teeth. There was no significance difference between the mean distance between mental foramen and alveolar margin of right  and left side.
Conclusion: The knowledge about variation in size, shape and position of mental foramen may be helpful to the dental surgeons to achieve full anesthesia after nerve block.
Key word: Mental foramen, Symphysis menti, Nerve block, Anesthesia.
