1. Ectopic bone formation on left maxillary sinus floor

Multiple globules of ectopic bone formation are present on the floor of the left maxillary sinus. These sites of ectopic bone formation appears to have mimicked partially-formed odontomas. However, no supernumerary teeth are present in this region. This is a nonsignificant incidental finding. No treatment is required.

Impacted tooth 25

Tooth 25 is vertically impacted with its crown in mild palatoversion. The crown of tooth 25 is positioned palatal to the apical half of the palatal root of tooth 24. The buccal surface of the crown of tooth 25 is rotated mesially by approximately 75 degrees. There is no evidence of root resorption on the adjacent permanent teeth. The deciduous tooth 65 exhibits normal physiologic resorption. Root development of tooth 25 appears 80% complete. The developing root apex of this tooth is located adjacent to the floor of the left maxillary sinus. The follicle surrounding the crown of this tooth appears hyperplastic. The periodontal ligament space surrounding the root circumference of tooth 25 is visualized, which suggests that it is not ankylosed. The crown of this tooth can be surgically accessed from the palatal aspect of the alveolar process, palatal to the apical half of the palatal root of tooth 24.

Axial views of tooth 25

These axial cross-sectional images demonstrate the normal appearance of the periodontal ligament space surrounding the root circumference of tooth 25. The follicle surrounding the crown of the tooth appears hyperplastic. These findings suggest that tooth 25 is not ankylosed.

Normal physiologic resorption of tooth 65

Tooth 65 exhibits normal physiologic resorption, given the patient's age at the time of image acquisition. Tooth 25 is located mesiopalatal to the palatal root of tooth 65.

Unaffected tooth 24

Tooth 24 is unaffected by the impacted tooth 25. The crown of tooth 25 is positioned palatal to the apical half of the palatal root of tooth 24.

Unaffected tooth 23

Tooth 23 is unaffected by the impacted tooth 25. The crown of tooth 25 is positioned distopalatal to the apical half of the root of tooth 23.

Axial views of the mid 2nd quadrant

These axial cross-sectional images demonstrate the palatal position of the impacted tooth 25 in the left maxilla. There is no evidence of root resorption on any of the permanent teeth captured in this imaging volume.
