FIGURE CAPTIONS
Figure 1: Panoramic radiograph illustrating bilateral maxillary
molar impactions, missing maxillary canines and mandibular KM’s.
Radiolucencies can be seen on 17 & 36 mesially.
Figure 2: Reformatted panoramic at 14 mm slice thickness
showing the course of the mandibular canals which transmit the
mandibular neurovascular bundle. The second mandibular molar roots were
bilaterally contiguous with the canal.
Figure 3: Orthogonal coronal slice (left) and corresponding
sagittal slice (right) at 150 microns confirm contact between the
inferior alveolar nerve (orange dot) and roots of 47. Thin lingual
cortex is noted as well as close proximity to inferior border of
mandible (3.3mm).
Figure 4: Orthogonal coronal slice (left) and corresponding
sagittal slice (right) at 150 microns confirms contact between the
inferior alveolar nerve (orange dot) and roots of 37. Thin lingual
cortex is noted as well as close proximity to inferior border of
mandible (4.6mm).
Figure 5: An illustration of the split view orthogonal coronal
sections employed in assessing the path of the inferior alveolar nerve.
Figure 6: Sagittal oblique sections at 150 microns showing the
nerve track and relationship with molar apices on both right (left
image) and left (right image) sides of the patient.
Figure 7: Axial view illustrating three rooted maxillary second
premolars (blue arrows) and transverse orientation of impacted 18 and 28
(red arrows).
