1. Rarefying osteitis on tooth 26DB+P

There is rarefying osteitis located periapical to the distobuccal and palatal roots of tooth 26. The floor of the maxillary sinus overlying these regions appears elevated and thinned. There is also widening of the periodontal ligament space around the mesiobuccal root apex of this tooth. The remaining periradicular bone appears normal, and there are no signs of root fracture.

These findings suggest that tooth 26 may be partially devitalized.

2. Apical delta canal in tooth 26P

An apical delta canal is evident within the apical third of the palatal root of tooth 26. The apical opening of this canal is located 1.5 mm distal to the main apical foramen of the palatal root of this tooth.

Axial views of tooth 26

These axial cross-sectional images demonstrate that the root canal system of tooth 26 is composed of distinct MB1, MB2, distobuccal, and palatal canals. The MB2 canal appears calcified.

Buccolingual views of tooth 26

These buccolingual cross-sectional images demonstrate that the buccal cortex overlying the distobuccal root apex of tooth 26 appears thinned and may be partially dehiscent. The contiguous palatal cortical plate appears intact. The floor of the maxillary sinus overlying the distobuccal and palatal root apices of this tooth appears thinned and elevated.

Mesiodistal views of tooth 26

These mesiodistal cross-sectional images demonstrate the periapical epicenter of rarefying osteitis associated with the distobuccal and palatal roots of tooth 26. There is also widening of the periodontal ligament space around the mesiobuccal root apex of this tooth. Note the presence of an apical delta canal located within the apical third of the palatal root of this tooth.

3. Recent extraction socket at site 27

Faint granular bone is evident lining the extraction socket at site 27, which indicates an early phase of healing. The density of this socket appears significantly lower than that of the adjacent trabecular bone, which suggests that this tooth was recently extracted.

4. Mild mucosal thickening and mucous retention cyst in left maxillary sinus

Mild mucosal thickening and mucous retention cyst formation are evident in the left maxillary sinus. These represent non-significant incidental findings.
