| Dental Dictionary: mental foramen |
A circular opening on the lateral aspect of the body of the mandible either below the apex of the first premolar or below the apex of the second premolar, but usually between the first and second premolars inferior to their apices. The mental vessels and nerve pass through this foramen to supply the lip. In edentulous mandibles, the bone may have been resorbed, so that it is in such a position that the denture base will cover it.

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].
Contents |
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[1].
