Sex-related differences in the distance of the mental foramen to the cementoenamel junction in adults: a study using cone beam computed tomography.

Injury to the contents of the mental foramen (MF) can be minimized by using cone beam computed tomography (CBCT) to determine the exact location of the MF prior to surgical procedures. In this retrospective study, variations in the vertical position of the MF between adult men and women older than 18 years were investigated using CBCT. The distance between the superior border of the MF and the most apical aspect of the cementoenamel junction (CEJ) of the mandibular second premolar was measured.
