Mental foramen and apical foramen: A dangerous anatomical proximity

The study evaluated the spatial position of the mental foramen (MF) using 300 cone‐beam computed tomography. The spatial position was analyzed with the horizontal location and relative location (distance between apical foramen and MF). The horizontal location was assessed through three positions (positions 1, 2, and 3). The relative location was determined with the x, y, and x coordinates of the root apex of mandibular premolars and the MF. Student's t‐test and chi‐square were performed. The most common horizontal location (52%) was position 2, which means between the premolars (p
