The mental foramen is associated with which nerves?

• A. Mental and incisive nerves
• B. Inferior alveolar and lingual nerves
• C. Buccal and mental nerves
• D. Incisive and lingual nerves

Answer: (A)

The mental foramen transmits the terminal branches of the inferior alveolar nerve. As the nerve trunk approaches the anterior mandible, it divides into two parts: one exits through the mental foramen as the mental nerve, supplying the chin and lower lip; the other remains within the canal and continues forward as the incisive nerve, which supplies the anterior teeth via the incisive canals. Because these two branches are the distal branches of the same nerve tract in the region of the mandible, the mental foramen is associated with both the mental nerve and the incisive nerve.
