File:Mandibular Incisive Canal Highlighted.jpg
The mandibular incisive canal (indicated here by coral green arrows) continuing anteriorly (to the right) from the mandibular canal (purple arrows) after the mental foramen (light green circle).

The mental foramen is one of two holes ("foramina") located on the anterior surface of the mandible. It permits passage of the mental nerve and vessels. The mental foramen descends slightly in edentulous individuals.[1]

Variations

The most frequent position (63%) of the mental foramen is in line with the longitudinal axis of the 2nd premolar tooth. Multiple mental foramina are observed in 17% of the sides. Only (4%) of the mandibles show bilateral multiple mental foramina. The majority of the multiple foramina are unequal in size: a single large foramen while the others are small (satellite) foramina. An incisive mental foramen is observed in 1% of the sides.[2]
