1. Rarefying osteitis on tooth 22: accessory mesial root

An accessory root has formed along the mesiopalatal surface of the coronal third of the primary root of tooth 22. This likely reflects a rare developmental anomaly. There is rarefying osteitis located periapical to the primary root apex of this tooth, but also around the apex of its accessory mesial root. These findings suggest the presence of inflammatory disease in association with a devitalized tooth 22, but clinical vitality testing is necessary to substantiate this interpretation.

Axial views of tooth 22

These axial cross-sectional images demonstrate that an accessory root has formed along the mesiopalatal surface of the coronal third of the primary root of tooth 22. The primary root canal system of this tooth is composed of a single, centrally positioned canal. The root canal system of the accessory root is not visualized radiographically, which suggests that the diameter of its canal is smaller than the spatial resolution of this imaging volume.

Buccolingual views of tooth 22

These buccolingual cross-sectional images demonstrate that the buccal cortex overlying the periapical region and the mesial aspect of tooth 22 appears thinned and partially dehiscent, which suggests the presence of draining sinus tracts. The contiguous palatal cortical plate appears thinned, but remains mostly intact.

Mesiodistal views of tooth 22

These mesiodistal cross-sectional images demonstrate the presence of rarefying osteitis located periapical to the primary root apex of tooth 22, and also around the apex of its accessory mesial root.
