1. Rarefying osteitis on tooth 44: unfilled lingual canal

The endodontically treated tooth 44 exhibits periapical rarefying osteitis. The existing obturation in this tooth is buccally positioned along the apical half of the root, which suggests the presence of a Weine's type IV root canal system with an unfilled lingual canal. The remaining periradicular bone appears normal. The buccal cortical plate appears thin and may be partially dehiscent overlying the apex of the root. These findings suggest persistent endodontic pathology in tooth 44 in association with incomplete obturation of its root canal system. The extruded endodontic material beyond the buccal root apical foramen is a non-significant finding.

Axial views of tooth 44

These axial cross sectional images demonstrate the completely obturated buccal canal of tooth 44, as well as the unobturated and probably calcified lingual canal of the tooth.

Mesiodistal views of tooth 44

These mesiodistal cross-sectional images demonstrate the rarefying osteitis in the periapical region of tooth 44. The remaining periradicular bone on the mesial and distal root surfaces of tooth 44 appears normal.

Buccolingual views of tooth 44

These buccolingual cross sectional images demonstrate the unobturated lingual canal of tooth 44. The buccal cortex overlying the apical half of the root of tooth 44 appears thin. This is likely secondary to the prominent buccal positioning of this root as opposed to the presence of periradicular pathology. The contiguous lingual cortical plate appears intact.
