Canaray 191205

Impacted tooth 18

Tooth 18 is mesioangularly impacted and the crown is oriented in mild palatoversion. The crown of tooth 18 is positioned distal to the apical third of the palatal root of tooth 17. The follicle appears normal and the periodontal ligament space is visible around the roots, which suggests ankylosis is unlikely to be present. No resorption is noted on tooth 17.

Axial views of tooth 18

These axial cross-sectional images demonstrate that the periodontal ligament space lining the root circumference of tooth 18 is visualized, which suggests the absence of ankylosis.

Mesiodistal views of posterior 1st quadrant

These mesiodistal cross-sectional images demonstrate the mesioangular orientation of tooth 18. The sinus floor is intact overlying the root of tooth 18.

Erupted tooth 28

Tooth 28 is vertically oriented and is slightly supraerupted in the left posterior maxillary alveolar process. The crown of tooth 28 is oriented in mild buccoversion. The roots of the tooth are fully formed and the overlying sinus floor is intact. There is no evidence of pathology associated with tooth 28, and no resorption is evident on tooth 27.

Axial views of tooth 28

These axial cross-sectional images demonstrate that the periodontal ligament space lining the root circumference of tooth 28 is visualized, which suggests the absence of ankylosis.

Mesiodistal views of posterior 2nd quadrant

These mesiodistal cross-sectional images demonstrate the vertical orientation of tooth 28. The sinus floor remains intact overlying the roots of tooth 28.

Left mandibular nerve buccal to tooth 38D + buccal and apical to tooth 38M

The left mandibular nerve courses buccal to the distal root apex, then passes buccal and slightly apical to the mesial root apex of the vertically impacted tooth 38. No nerve compression is present. The residual follicle appears normal and the periodontal ligament space is visible around the entire root circumference, which suggests this tooth is not ankylosed. Tooth 38 has not caused damage to the distal surface of tooth 37.

Axial views of tooth 38

These axial cross-sectional images demonstrate the buccal passage of the left inferior alveolar nerve canal relative to the distal root apex of tooth 38, as well as the buccal and the apical position of the nerve relative to the mesial root apex. There is no evidence of ankylosis.

Mesiodistal views of tooth 38

These mesiodistal cross-sectional images demonstrate the vertical orientation of tooth 38 relative to the long-axis of tooth 37. Tooth 38 has not caused any resorption of the adjacent tooth 37.

Additional views of tooth 38 with clinical photo of extracted mesial root

These images demonstrate a distal curvature of the apical third of the mesial root of tooth 38 based on the cone beam CT scan. However, the clinical photo reveals a much more prominent, near-90 degree dilaceration within the apical half of the root.
