Right inferior alveolar nerve canal lingual to 48B, buccal to 48M+ML+L, and inferior to dilacerated 48D

The right inferior alveolar nerve canal passes through a furcation formed by the buccal root of tooth 48 with its mesial, mesiolingual, and lingual roots. The nerve canal appears completely enveloped by the buccal and lingual roots of this tooth, as their apices are in direct contact with each other. The nerve canal also passes inferior to the distal root of this tooth. There is mild compression of the nerve canal in these regions.

Atypical root form in tooth 48

Tooth 48 is mesioangularly impacted and a morphologic variant with five distinct roots: mesial, mesiolingual, lingual, distal, and buccal. The buccal root apex of this tooth curves lingually to contact the apical third of its lingual root. The distal root of this tooth is dilacerated in a distal direction. The residual follicle surrounding the crown tooth 48 appears normal, and there are no signs of ankylosis.

No evidence of ankylosis in tooth 48

These axial cross-sectional images demonstrate that tooth 48 is a morphologic variant with distinct mesial, mesiolingual, lingual, distal, and buccal roots. The periodontal ligament space surrounding the root circumference of this impacted tooth is visualized, which suggests that it is not ankylosed. The right inferior alveolar nerve canal courses through the furcation formed by the buccal root of tooth 48 with its mesial, mesiolingual, and lingual roots, and then inferiorly to its distal root.

No damage to tooth 47

There is no radiographic evidence of root resorption in tooth 47 due to its close proximity to the impacted tooth 48.

Mesiodistal views of tooth 48

These mesiodistal cross-sectional images demonstrate the mesioangular orientation of tooth 48 relative to the long-axis of tooth 47, and the normal appearance of its residual follicle. Note the distal dilaceration of the distal root of tooth 48.

Left inferior alveolar nerve canal lingual to tooth 38M+D

Tooth 38 is mesioangularly impacted and partially erupted. The left inferior alveolar nerve canal passes immediately lingual to the apical thirds of the mesial and distal roots of this tooth. There is mild compression of the nerve canal in these regions. The periodontal ligament space surrounding the root circumference of this impacted tooth is visualized, which suggests that it is not ankylosed. The residual follicle surrounding the crown of tooth 38 appears normal. This tooth has not caused any resorption of 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 roots of tooth 38. The periodontal ligament space lining the root circumference of this tooth is visualized, which suggests the absence of ankylosis.

Mesiodistal views of tooth 38

These mesiodistal cross-sectional images demonstrate the slightly mesioangular orientation of tooth 38 relative to the long-axis of tooth 37. The residual follicle surrounding the crown of this tooth appears normal. The mesial and distal roots of this tooth are curved toward each other. There is no evidence of root resorption in the adjacent tooth 37.
