Canaray 156563

Impacted tooth 23

The crown of the mesioangularly impacted tooth 23 is positioned palatal to the root of tooth 22. There is no evidence of root resorption on the adjacent permanent teeth. However, the roots of teeth 22 and 24 have been displaced. The root of tooth 23 is fully formed and the root apex abuts the nasal floor. The periodontal ligament space appears normal surrounding the root of the tooth. The crown of the tooth has partially erupted through the alveolar crest. The residual follicle surrounding the crown of the tooth appears normal. These findings suggest that the tooth is not ankylosed. The crown of tooth 23 can be surgically accessed from the palatal aspect of the alveolar process at site 22.

Comparison of prior and current scan

The prior case (Canaray case 149841, dated 12 October 2017, shown in redscale) was superimposed over the current scan (shown in greyscale). Tooth 23 has changed positions in the interval between scans. Specifically, the crown has rotated distally and the root has rotated mesially.

Axial views of tooth 23

These axial cross-sectional images demonstrate the normal appearance of the periodontal ligament space surrounding the root of tooth 23. The crown of the tooth has partially erupted through the alveolar crest. The residual follicle surrounding the crown of the tooth appears normal. These findings suggest that the tooth is not ankylosed.

Unaffected tooth 21

Tooth 21 is unaffected by the impacted tooth 23. The cusp tip of tooth 23 is positioned palatal to the root of tooth 21.

Buccally displaced root of tooth 22

The root of tooth 22 has been buccally displaced by the impacted tooth 23. There is no evidence of root resorption on tooth 22. The crown of tooth 23 is positioned palatal to the root of tooth 22.

Mildly buccally displaced root of tooth 24

The root of tooth 24 has been mildly buccally displaced by the impacted tooth 23. There is no evidence of root resorption on tooth 24. The apical third of the root of tooth 23 is positioned apical and palatal to the root apex of tooth 24.

Axial views of anterior 2nd quadrant

These axial cross-sectional images demonstrate the palatal position of the crown of the impacted tooth 23 relative to the root of tooth 22. The roots of teeth 22 and 24 have been displaced. There is no evidence of root resorption on any of the permanent teeth captured in this imaging volume.
