Left inferior alveolar nerve canal lingual to tooth 38 + probable ankylosis

The left inferior alveolar nerve canal passes immediately lingual to the apical thirds of the mesial and distal roots of the vertically impacted tooth 38. There is moderate compression of the nerve canal in these regions. Root development is complete in tooth 38, and its roots are fused at their apices. The apical two-thirds of the mesial root of tooth 38 is dilacerated in a distal direction. The periodontal ligament space is not completely visualized around the root circumference of this impacted tooth, which suggests the possibility of ankylosis. The residual follicle surrounding the crown of this tooth appears hypoplastic. This tooth has not caused any damage to the adjacent tooth 37.

Axial views of tooth 38

These axial cross-sectional images demonstrate the lingual passage of the left inferior alveolar nerve canal relative to the apical thirds of the roots of tooth 38. Also evident in these cross-sections is the incomplete visualization of a periodontal ligament space surrounding the root circumference of tooth 38, which suggests the possibility of ankylosis.

Mesiodistal views of tooth 38

These mesiodistal cross-sectional images demonstrate the distal dilaceration of the apical two-thirds of the mesial root of tooth 38, and the fusion of its mesial and distal roots at their apices.

Right inferior alveolar nerve canal enveloped by tooth 48M+DL, and lingual to 48DB

Tooth 48 is vertically impacted and demonstrates an atypical root morphology, with distinct distobuccal and distolingual roots, and a mesial root which curves distally with a superiorly dilacerated root apex. The mesial and distolingual root apices of tooth 48 are fused. The right inferior alveolar nerve canal passes lingual to the apical third of the distobuccal root of tooth 48, and is completely enveloped by its mesial and distolingual roots. The nerve canal is mildly compressed in these regions. The periodontal ligament space is not completely visualized around the root circumference of this impacted tooth, which suggests the possibility of ankylosis. The residual follicle surrounding the crown of tooth 48 appears hypoplastic. This tooth has not caused any damage to the adjacent tooth 47.

Axial views of tooth 48

These axial cross-sectional images demonstrate the presence of three distinct roots in tooth 48: mesial, distobuccal, and distolingual. The right inferior alveolar nerve canal is enveloped by the mesial and distolingual roots of tooth 48, and passes lingual to its distobuccal root.

Mesiodistal views of tooth 48

These mesiodistal cross-sectional images demonstrate the pronounced distal curvature of the mesial root of tooth 48, and the superior dilaceration of the apex of this root.
