1. Bone loss at tooth 41M

Vertical bone loss is present at the mesial surface of the root of tooth 41. This bone loss extends from the alveolar crest to the level of the apical third of the root of the tooth. The bone surrounding the apical foramen of the tooth appears normal, which suggests that the tooth may not be endodontically compromised, and that this bone loss has an origin within the periodontium.

Incidentally, an artifact is present in this CT scan, which extends through the buccal aspect of the crown of the tooth and mimics a crack or fracture. However, no fractures are present within the crown.

Axial views of tooth 41

These axial cross-sectional images demonstrate the vertical bone loss along the mesial surface to the apical third of the root of tooth 41. The remaining alveolar bone around the root surfaces of the tooth appears normal. Note the artifact on the buccal aspect of the crown of tooth 41.

Mesiodistal views of tooth 41

These mesiodistal cross-sectional images demonstrate the vertical bone loss along the mesial surface of the root of tooth 41, which extends from the alveolar crest to the apical third of the root. The periradicular bone along the distal aspects of the root of the tooth appears normal. No signs of root fracture are evident.

Buccolingual views of tooth 41

These buccolingual cross-sectional images demonstrate the vertical bone loss along the mesial surface of the root of tooth 41, which extends to the level of the apical third of the root. No periapical pathology is present.

2. Normal tooth 31

The bone at the mesial surface of the root of tooth 31 appears intact. The defect originating at the mesial aspect of tooth 41 has not affected the root of tooth 31. Tooth 31 is not the source of any pathology.

Axial views of tooth 31

These axial cross-sectional images demonstrate the normal appearance of the periodontal ligament space and lamina dura surrounding the root circumference of tooth 31. No signs of root fracture are present.

Buccolingual views of tooth 31

These buccolingual cross-sectional images demonstrate that the buccal and lingual cortical plates overlying the root of tooth 31 appear thin, but intact. No periapical pathology is present.

Mesiodistal views of tooth 31

These mesiodistal cross-sectional images demonstrate the normal appearance of the periapical and periradicular bone surrounding the root of tooth 31. There are no signs of endodontic pathology. The defect originating at the root of tooth 41 has not affected the root of tooth 31.

3. Embedded metal in the anterior left mandible

An embedded metal object is present in the anterior left mandibular body. This structure has been partially captured in this scan, and may represent a fixation wire from a prior surgery.

4. Lingual mandibular tori

Lingual tori composed of cortical bone are present along the alveolar process of the right and left mandible adjacent to the canine and premolar regions. This is a non-significant incidental finding.
