1. Malformed root canal system of tooth 45

Tooth 45 has a malformed root canal system. The diameter of the canal in the coronal two thirds of the root is wide, and reaches a maximum diameter at the level of the apical third of the root, where it extends through the buccal root surface. The rarefying osteitis that is present on the buccal surface of the root of tooth 45 appears to originate at the defect on the lateral surface of the apical third of the root. No pathology is present in the periapical region of the tooth. This radiographic appearance may represent internal resorption, or malformation of the root secondary to a history of trauma or infection.

Axial views of tooth 45

These axial cross-sectional images demonstrate the wide diameter of the root canal of tooth 45 at the midroot level, as well as the defect that is present on the buccal surface of the apical third of the root. The rarefying osteitis that extends along the buccal surface of the coronal two thirds of the root of tooth 45 originates at the defect on the buccal surface of the apical third of the root. Note the absence of any periapical pathology at tooth 45. The right mental foramen is positioned buccally to the root apex of the tooth, and has not been affected by the rarefying osteitis that originates on the buccal surface of the apical third of the root.

Mesiodistal views of tooth 45

These mesiodistal cross-sectional images demonstrate the flared segment of the canal which extends through the buccal surface of the apical third of the root of the tooth.

Buccolingual views of tooth 45

These buccolingual cross-sectional images demonstrate the rarefying osteitis on the buccal surface of the coronal half of the root of the tooth, which originates at the defect on the buccal surface of the apical third of the root.

2. Buccal abrasion on tooth 46

Tooth 46 exhibits buccal abrasion at the level of the cementoenamel junction. This is a non-significant incidental finding. Tooth 46 appears normal otherwise.
