Canaray 199835

Left mandibular nerve completly enveloped by 38MB+ML

The impacted tooth 38 is mesioangularly oriented. The residual follicle surrounding the crown of the tooth appears normal. Root formation is almost complete.

The left inferior alveolar nerve canal courses through the furcation in the apical halves of the mesiolingual and dilacerated mesiobuccal roots of tooth 38, and is mildly compressed. The nerve is completely enveloped by the mesiobuccal and mesiolingual roots, which could have implications for the potential for iatrogenic nerve damage upon the surgical removal of the tooth. The nerve passes through the furcation in the apical halves of the dilacerated distal roots of the tooth and is mildly compressed.

The adjacent tooth 37 exhibits caries and resorption, but does not exhibit displacement.

Axial views of the posterior 3rd quadrant

These axial cross sectional images of the posterior 3rd quadrant demonstrate the passage of the nerve through the furcation of mesial and distal roots of tooth 38.

Mesiodistal views of posterior 3rd quadrant

These mesiodistal cross sectional images of the posterior 3rd quadrant demonstrate the mesioangular orientation of the impacted tooth 38 and the normal residual follicle surrounding the crown of the tooth. The presence of multiple dilacerations is evident in these images. The adjacent tooth 37 exhibits caries and resorption, but does not exhibit displacement.

Roots of tooth 48 almost completely encircle the right mandibular nerve

The impacted tooth 48 is mesioangularly oriented. The residual follicle surrounding the crown of the tooth appears normal. Root formation is almost complete.

The right inferior alveolar nerve canal passes through the furcation in the apical halves of the mildly curved distal roots of tooth 48, and is mildly compressed. The nerve passes through the furcation in the midroot region of the mesiolingual and prominently curved mesiobuccal roots of the tooth and is mildly compressed. Note that the apices of the mesiobuccal and distobuccal roots curve around the inferior border of the inferior alveolar nerve canal, which increases the risk of iatrogenic nerve damage upon surgical removal of the tooth.

The adjacent tooth 47 does not exhibit caries, resorption, or displacement.

Axial views of the posterior 4th quadrant

These axial cross sectional images of the posterior 4th quadrant demonstrate the passage of the nerve through the furcation of distal and mesial roots of tooth 48.

Mesiodistal views of posterior 4th quadrant

These mesiodistal cross sectional images of the posterior 4th quadrant demonstrate the mesioangular orientation of the impacted tooth 48 and the normal residual follicle surrounding the crown of the tooth. Note the presence of a prominent curve in the mesiobuccal root of the tooth. The adjacent tooth 47 does not exhibit caries, resorption, or displacement.
