Fig. 1. Dental panoramic radiograph of 60-year-old woman with normal
cortex. We drew line parallel to long axis of mandible and tangential to
inferior border of mandible and constructed dotted line perpendicular to this
tangent intersecting inferior border of mental foramen, along which mandibular
cortical width was measured. Distance between two parallel solid lines is
cortical width. Arrow shows mental foramen.
