Impacted tooth 23

The crown of the vertically impacted tooth 23 is positioned mesial and slightly palatal to the apical third of the root of tooth 24. There is no evidence of root resorption in teeth 22 and 24. However, the root of tooth 24 has been distobuccally displaced.

The crown of tooth 23 has partially erupted through the buccal aspect of the alveolar process. The residual follicle surrounding the crown of the tooth appears hyperplastic. The root of tooth 23 is 95% formed and exhibits a slight distally oriented apical curve. The periodontal ligament space surrounding the root of the tooth appears normal and the lamina dura is intact. No signs of ankylosis are present.

The root of tooth 63 exhibits mild root resorption and has likely hindered the eruption of tooth 23. Tooth 63 may be extracted in order to facilitate the eruption of tooth 23. Tooth 23 can be surgically accessed from the buccal aspect of the alveolar process, in the region mesial to the root of tooth 24.

Axial views of tooth 23

These axial cross-sectional images demonstrate that the periodontal ligament space lining the root circumference of tooth 23 is visualized, which suggests ankylosis is not present. The crown of tooth 23 has partially erupted through the buccal aspect of the alveolar process. The residual follicle surrounding the crown of the tooth appears hyperplastic.

Distobuccally displaced root of tooth 24

The root of tooth 24 has been distobuccally displaced by the impacted tooth 23. There is no evidence of root resorption in tooth 24. The crown of tooth 23 is positioned mesial and slightly palatal to the apical third of the root of tooth 24.

Mild physiologic resorption of tooth 63

Tooth 63 exhibits mild signs of physiologic resorption adjacent to the crown tip of tooth 23. This tooth may therefore require extraction in order to facilitate the eruption of tooth 23.

1. Dens invaginatus in tooth 22

A centrally positioned, enamel lined cavity extends from the crown of tooth 22 to the middle third of its root. These findings are consistent with dens invaginatus. Tooth 22 has been devitalized, and exhibits a broad zone of periapical rarefying osteitis that extends into the pericoronal region of tooth 23. Dentin formation has been arrested on the surface of the root canal of tooth 22, and the root exhibits thin walls. Tooth 22 does not appear to be restorable. In addition, the shape of the crown of tooth 22 is unusual.

unsure how to comment on this tooth as it does not appear normal radiographically

Description

Axial views of the anterior 2nd quadrant

These axial cross-sectional images demonstrate the mesial and slightly palatal position of the crown of the mesioangularly impacted tooth 23 relative to the root of tooth 24. The root of tooth 24 has been distobuccally displaced by the impacted tooth 23. There is no evidence of root resorption in any of the permanent teeth captured in this imaging volume. The dens invaginatus at tooth 22 is also evident in this image.

2. Dense bone island at site 25P

A dense bone island is present in the palatal aspect of the alveolar process at site 25. This dense bone island demonstrates no effects on its surrounding structures.

3. Mild mucositis of left maxillary sinus

The left maxillary sinus exhibits mild mucositis, which represents an incidental finding with no clinical significance.
