Right inferior alveolar canal lingual to tooth 48D and through apical notch of 48M

The right inferior alveolar canal passes immediately lingual to the developing distal root apex of the mesioangularly impacted tooth 48, and then through an apical notch formed by its fused mesiobuccal and mesiolingual roots. The nerve canal is mildly compressed by these roots. Root development is 95% complete and the mesial and distal roots converge at their apices. The periodontal ligament space surrounding the roots of tooth 48 is visualized, suggesting that this tooth is not ankylosed. The residual follicle around the tooth 48 crown appears normal. There is no damage to the adjacent tooth 47.

Axial views of tooth 48

These axial cross-sectional images demonstrate the lingual course of the inferior alveolar nerve canal relative to the developing distal root apex of tooth 48, and its passage through an apical notch formed by the developing mesiobuccal and mesiolingual roots.

1. Caries on tooth 38O

There is a focus of caries located just deep to the occlusal surface of tooth 38 which does not encroach on the pulp chamber.

Left inferior alveolar canal inferior to tooth 38

Tooth 38 is vertically impacted and rotated, with its mesial surface facing the buccal cortex. The left inferior alveolar canal passes immediately inferior to the developing root apices of tooth 38. The nerve canal is mildly compressed by these roots. Root development is 95% complete and the mesial and distal roots converge at their apices. The periodontal ligament space surrounding the roots of tooth 38 is visualized, suggesting that this tooth is not ankylosed. The residual follicle around the tooth 38 crown appears slightly hypoplastic. There is no damage to the adjacent tooth 37.

2. Osteoma lingual to tooth 33

There is a mass located just lingual to the tooth 33 crown, which appears to extend coronally from the alveolar crest. This mass has an internal structure consisting of granular bone with a thin cortical periphery. This bony mass is continuous with the lingual cortex of the alveolar process at the level of the cemento-enamel junction of tooth 33. In the clinical photo, the soft tissue overlying this mass appears pink and intact. This mass has not caused any effects on surrounding structures. These findings suggest the presence of an osteoma. Monitoring of this area for continued growth is recommended, but given the prominent location of this mass, surgical excision may be also be considered.

These axial cross-sectional images demonstrate the continuity of the osteoma with the lingual cortex of the alveolar process adjacent to tooth 33. Note that the internal structure of the entity is composed of granular bone surrounded by a thin cortical periphery.
