1. Periapical rarefying osteitis at tooth 11
Tooth 11 exhibits periapical rarefying osteitis. The bone surrounding the remaining root surfaces of the tooth appears normal. This suggests that the rarefying osteitis is secondary to a persistent endodontic lesion. No signs of root fracture are present in the tooth. No unobturated canals are radiographically evident. A small amount of endodontic sealer has been extruded through the apical foramen of the tooth. Overall, this radiographic appearance is suggestive of a recent or failing endodontic treatment in tooth 11.
Axial views of tooth 11
These axial cross-sectional images demonstrate the periapical rarefying osteitis at the root of tooth 11. The remaining alveolar bone around the root surfaces of the tooth appears normal. A single, centrally positioned root canal system is present.
Mesiodistal views of tooth 11
These mesiodistal cross-sectional images demonstrate the normal appearance of the periradicular bone located mesial and distal to the root of tooth 11. The periapical rarefying osteitis at the root of the tooth, as well as the extruded endodontic sealer from the apical foramen of the root is evident in these images.
Buccolingual views of tooth 11
These buccolingual cross-sectional images demonstrate the rarefying osteitis and the extruded sealer in the periapical region of the root of tooth 11. The contiguous buccal and palatal cortical plates remain intact. No signs of root fracture are present.
2. External resorption at tooth 23Bu
Tooth 23 exhibits external resorption on the buccal surface of its root at the midroot level. This resorption has a fairly well-defined periphery and an ovoid shape. The root canal of the tooth has not been affected. No endodontic pathology is present.
