Figure 1a: Serial presentation of CT findings of the upper jaw and teeth, showing normal appearance of alveolar and cancellous bone (arrow).
Figure 1b: Serial presentation of CT findings of the lower jaw and teeth, showing normal appearance of alveolar bone (upper arrow) but no trabecular bone although the cortical bone is intact (lower arrow); There appears to be a demarcation line where the teeth end and below which the bone is ‘hollow’. There is apparent root resorption on the lower anterior teeth and blunting of the roots on the lower first molars bilaterally.
