FIG1
Initial evaluation of the overall anatomy was done using 3D volumetric reconstruction, which showed three mental foramina on the captured section of the left body of the mandible (Figure 1). All three foramina were located apically to the root of tooth 20 within a few millimeters of each other (Figure 1).
Axial cross-section images at 0.25 mm intervals show the presence of three mental foramina.

These cross-sections were then analyzed in multiple sequential cross-sections for the detailed proximity of these multiple foramina (Figures 2-3).

These cross-sections were then analyzed in multiple sequential cross-sections for the detailed proximity of these multiple foramina (Figures 2-3).

FIG4
The superior most foramina measured approximately 1.63 mm in the anteroposterior direction, the mid-level foramina measured 3.27 mm in the anteroposterior direction, and the inferior most foramen measured 3.20 mm in the anteroposterior direction (Figure 4).
Panoramic radiograph: the three mental foramina are not visualized on the left side.
