Canaray 169300

Normal bone at site 46

The bone at site 46 appears normal radiographically and exhibits a density that is similar to that of the adjacent trabecular bone. No intraosseous pathology is present.

1. Periapical rarefying osteitis on tooth 17

Tooth 17 is a morphologic variant with fused roots. Rarefying osteitis is present on the mesiobuccal and palatal aspect of the fused root. The existing obturations in the mesiobuccal and palatal canals of tooth 17 extend slightly past their radiographic apices. An unobturated MB2 canal may be present in the isthmus between the fused mesiobuccal and palatal roots. This is likely the source of the persistent periapical rarefying osteitis.

The remaining periradicular bone appears normal. There are no signs of a root fracture.

2. Widened PDL space on tooth 16MB

The periapical periodontal ligament space on the mesiobuccal root of tooth 16 is widened. The existing obturation in the mesiobuccal root is buccally positioned and an unfilled MB2 canal is suspected. This appearance is suggestive of persistent low-grade endodontic pathology due to the incomplete obturation of the mesiobuccal root of tooth 16.

The distobuccal root of tooth 16 exhibits a healed post-treatment appearance. The existing obturation in the palatal root of the tooth extends past the radiographic apex and a small region of low density bone is present. The remaining periradicular bone appears normal. There are no signs of a root fracture.

3. Exposed threads on implant 27

The coronal half of the implant at site 27 is not embedded in bone. The apex of the implant abuts the floor of the left maxillary sinus. The mesial and distal surfaces of the implant cannot be visualized due to the presence of beam hardening artifacts. A periapical radiograph is necessary to evaluate this region of the implant at site 27.

4. Exposed threads on implant 26

The coronal half of the implant at site 26 is not embedded in bone. The apex of the implant extends through the sinus floor. No significant mucositis overlies the implant apex. The mesial and distal surfaces of the implant cannot be visualized due to the presence of beam hardening artifacts. A periapical radiograph is necessary to evaluate this this region of the implant at site 26.

5. Localized fibrous dysplasia in anterior left maxilla

A localized zone of fibrous dysplasia is present in the anterior left maxilla in the region apical to teeth 22, 23, and 24. The periphery of the fibrous dysplasia is continuous with the adjacent trabecular bone, and the internal structure is heterogeneous. Zones of granular bone of varying density are dispersed within the lesion. Mild localized expansion of the maxilla has occurred. There is no treatment for this entity.

6. Palatal exostosis adjacent to site 18

A small exostosis composed of cortical and trabecular bone is present adjacent to site 18. This is an incidental finding with no significance.

7. Dense bone island apical to tooth 34

A small dense bone island is present within the alveolar process, apical and lingual to the root apex of tooth 34. This dense bone island has not had any effects on its surrounding structures and is a non-significant incidental finding.

8. Mild mucositis of left maxillary sinus

The left maxillary sinus exhibits mild mucositis, which represents an incidental finding with no clinical significance.

Sagittal views of the right maxillary sinus: No impediment for sinus lift surgery

These sagittal cross-sectional images demonstrate the normal mucosal thickness in the right maxillary sinus. There is no potential impediment for sinus lift procedure.

9. Multiple subcutaneous calcifications

Subcutaneous calcifications are dispersed throughout the facial region. This is an incidental finding with no clinical significance.

10. Left palatine tonsillolith

A tonsillolith is present in the left palatine tonsil. This is an incidental finding with no clinical significance.
