Canaray 58261

1. Radicular cyst at tooth 16

A radicular cyst is present in the periapical regions of the mesiobuccal and distobuccal roots of tooth 16. The cyst has displaced the sinus floor superiorly and has perforated through the buccal cortex of the alveolar process adjacent to the mesiobuccal root apex of tooth 16. This is suggestive of a persistent endodontic failure at the mesiobuccal or distobuccal root of the tooth. The palatal root of the tooth appears normal.

Axial views of tooth 16

These axial cross sectional images demonstrate the unilocular radicular cyst that appears to originate from the mesiobuccal root of tooth 16. No unfilled canals are radiographically evident.

Sagittal views of tooth 16

These sagittal cross sectional images demonstrate the widened periodontal ligament space around the apical half of the mesiobuccal root of tooth 16, as well as the normal appearance of the implant at site 15. Mild periodontal bone loss is present around the mesiobuccal root of tooth 17.

Coronal views of tooth 16

These coronal cross sectional images demonstrate the dehiscence in the buccal cortical plate adjacent to the mesiobuccal root apex of tooth 16.

Normal implant 15

The implant at site 15 appears fully osseointegrated, and is not the source of the patient's symptoms.

2. Moderate mucositis in right maxillary sinus

Moderate mucositis is present on the floor of the right maxillary sinus. This is an incidental finding which is likely secondary to the radicular cyst at tooth 16.
