Mental spines are small, midline, paired, bony protuberances (or eminences) of the posterior lingual surface of the mandible. There are usually two superior and two inferior spines. They represent the anchor points of origin of the superior genioglossus and the inferior geniohyoid muscles ^1,2. Collectively the four spines are called the genial tubercle ⁴.

Centrally between the spines, there is the lingual or mental foramen.

Avulsion fractures of the mental spines can occur either due to repeated microtrauma caused by removable dentures or as part of mandibular fractures due to blunt or penetrating trauma ¹.
