Canaray 46892

Site 46: Adequate bone

A 5x14mm cylinder was overlaid on the adjacent images at site 46. Adequate bone exists for implant placement at this site.

Site 47: Adequate bone

A 5x14mm cylinder was overlaid on the adjacent images at site 47. Adequate bone exists for implant placement at this site.

2. Rarefying osteitis on tooth 47D

The distal root apex of tooth 47 exhibits periapical rarefying osteitis. This pattern of bone loss is most suggestive of persistent periapical pathology due to failed endodontic treatment of tooth 47.

1. Rarefying osteitis on tooth 47M: unfilled buccal + lateral canal

The mesiobuccal surface of the mesial root of endodontically treated tooth 47 exhibits rarefying osteitis, which involves the coronal and middle thirds of the root and communicates with the alveolar crest. The existing endodontic obturation in the middle third of the mesial root of tooth 47 is lingually positioned, and an unfilled buccal canal is present in this area. This unfilled buccal canal is associated with a lateral canal, the foramen of which is located at the center of the region of rarefying osteitis involving the mesial root of tooth 47.

Axial views of tooth 47

These axial cross sectional images demonstrate the presence of rarefying osteitis along the mesiobuccal aspect of the mesial root of tooth 47. This area of rarefying osteitis has resulted from an unfilled buccal canal and accompanying lateral canal in the middle third of the mesial root of tooth 47.

Sagittal views of tooth 47

These sagittal cross sectional images demonstrate the presence of an unfilled lateral canal associated with the unfilled buccal canal in the mesial root of tooth 47. The epicenter of the area of rarefying osteitis associated with the mesial root of tooth 47 is at the foramen of this unfilled lateral canal.

3. Hypercementosis on tooth 44

The apical third of the root of tooth 44 exhibits hypercementosis. This represents an incidental finding, and would be of clinical significance only if future extraction of tooth 44 was required.
