1. Large sequestered bone fragment in lingual third quadrant

A large sequestered bone fragment is present at the lingual aspect of the alveolar process in the region lingual to sites 32, 33, 34, 35, and 36. No periosteal bone formation is present in this region, which is typical of bisphosphonate-related osteonecrosis. The adjacent bone is sclerotic. The teeth in the third quadrant do not exhibit any periapical pathology, and have not been significantly affected by the sequestered bone fragment.

Axial views of third quadrant

These axial cross-sectional images demonstrate that the large sequestered bone fragment is present at the lingual aspect of the alveolar process in the third quadrant. Note the sclerotic appearance of the surrounding bone, and the absence of any periapical pathology in the third quadrant.

Buccolingual views of third quadrant

These buccolingual cross sectional images demonstrate the complete sequestration of the fragment of bone on the lingual aspect of the alveolar process in the third quadrant.

Mesiodistal views of third quadrant

These mesiodistal cross sectional images demonstrate the slightly irregular shape of the sequestered bone fragment at the lingual aspect of the alveolar process in the third quadrant. The sequestrum has fully separated from the adjacent bone.

Normal tooth 35

Tooth 35 appears normal radiographically, and does not exhibit any periapical pathology. This suggests that the endodontic treatment of this tooth has been successful, and that this tooth is not the source of any pathology in this region.
