2. Periapical rarefying osteitis on tooth 12
Tooth 12 exhibits periapical rarefying osteitis that extends through the buccal cortex of the maxillary alveolar process. This radiographic appearance is most suggestive of the presence of persistent endodontic pathology associated with tooth 12.
1. Developmental groove on tooth 12 + vertical bone loss
A developmental groove is present along the mesiopalatal surface of the root of tooth 12, extending from the cingulum to the apical third of the root. This cleft has resulted in vertical periodontal bone loss, which extends to communicate with an area of periapical rarefying osteitis. The presence of this developmental groove suggests tooth 12 is likely unrestorable.
Axial views of tooth 12
These axial cross-sectional images demonstrate the developmental groove along the mesiopalatal surface of the root of tooth 12, which has resulted in a contiguous area of periradicular bone loss.
Mesiodistal views of tooth 12
These mesiodistal cross-sectional images demonstrate the intact periradicular bone along the mesial and distal surfaces of the root of tooth 12. Persistent periapical pathology is evident.
Buccolingual views of tooth 12
These buccolingual cross-sectional images demonstrate dehiscence of the buccal cortical plate overlying the area of rarefying osteitis at the root apex of tooth 12. Periradicular bone loss extending along the mesiopalatal surface of the root is the result of a developmental groove in this area.
3. Right antral pseudocyst
An antral pseudocyst is present within the right maxillary sinus. This represents an incidental finding with no clinical significance.
