1. Resorption on tooth 12

Resorption is present in the coronal third of the root of tooth 12. The periodontal ligament space is not visible at the distal surface of the coronal third of the root of the tooth, which suggests that the tooth is ankylosed in this region . The root apex of tooth 12 is mesiobuccally displaced and the buccal surface of the crown is rotated mesially by approximately 30 degrees. The apical half of the root of tooth 12 is positioned distobuccal to the apical half of the root of tooth 11. No damage is present on the adjacent permanent teeth. The root apex of tooth 12 exhibits a prominent distal curve. The root of tooth 12 appears fully formed.

Axial views of tooth 12

These axial cross-sectional images demonstrate the normal appearance of the periodontal ligament space surrounding the root of tooth 12. Note the absence of a visible periodontal ligament space at the distal surface of the coronal third of the root of the tooth, which is indicative of the presence of ankylosis. Note the resorption in the coronal third of the root of the tooth.

Normal tooth 13

Tooth 13 is unaffected by tooth 12. The crown of tooth 13 is positioned distal to the crown of tooth 12. No root resorption or damage has occurred to tooth 13.

Normal tooth 11

Tooth 11 has not been affected by tooth 12. The apical half of the root of tooth 12 is positioned distobuccal to the apical half of the root of tooth 11. No resorption is evident at tooth 11.

Axial views of anterior 1st quadrant

These axial cross-sectional images demonstrate the resorption, displacement, ankylosis, and rotation of tooth 12. Teeth 11 and 13 are unaffected by tooth 12.
