1. Ameloblastoma in anterior right mandible

There is a well-defined, non-corticated, multi-locular radiolucent entity located within the anterior right mandible, which extends from the mesial root surface of tooth 31 to the mesiolingual root surface of tooth 43, and from the level of the alveolar crest to the periapical regions of these teeth. This entity has caused root resorption in the apical thirds of the roots of teeth 41 and 42, and expansion along the buccal and lingual surfaces of the alveolar process. The overlying alveolar crest and buccal and lingual cortical plates appear thinned and partially dehiscent.

These findings are suggestive of an ameloblastoma. However, biopsy with histopathologic correlation is necessary to substantiate this interpretation.

No evidence of root resorption in tooth 31

These additional orthogonal cross-sectional images demonstrate that the radiolucent entity in the anterior mandible abuts the mesial surface of the apical half of the root of tooth 31, but there is no evidence of root resorption.

2. Apical resorption in tooth 41

These additional orthogonal cross-sectional images demonstrate that, due to its close proximity to the radiolucent entity, mild apical resorption is evident around the circumference of the apical third of the root of tooth 41.

3. Apical resorption in tooth 42

These additional orthogonal cross-sectional images demonstrate that, due to its close proximity to the radiolucent entity, external resorption is evident around the apical third of the root of tooth 42.

No evidence of root resorption in tooth 43

These additional orthogonal cross-sectional images demonstrate that the radiolucent entity in the anterior mandible abuts the mesiolingual surface of the middle third of the root of tooth 43, but there is no evidence of root resorption.

4. Lingual mandibular tori

Lingual tori composed of cortical bone are present in the alveolar process of the mandible adjacent to teeth 34 and 44. This is an anatomic variant.
