1. History of bone grafting distal to tooth 21

Dense granular bone is evident along the distal and palatal aspects of the apical two-thirds of the root of tooth 21. The bone graft appears fully osseointegrated with the surrounding trabecular bone. In comparison to the original scan dated December 29, 2014 (case ID: 26389), the previously observed lytic bone loss is now completely filled with bone graft material. There is no radiographic evidence of intraosseous pathology in the present scan.

Normal tooth 21

Tooth 21 appears normal radiographically. The periodontal ligament space appears thin and uniform, and the lamina dura is intact. There is no evidence of endodontic pathology or a displaced root fracture in this tooth.

Axial views of tooth 21

These axial cross-sectional images demonstrate that the root canal system of tooth 21 is composed of a single, centrally positioned root canal. Note that the periodontal ligament space lining the root circumference of this tooth appears thin and uniform, and the lamina dura intact. Dense granular bone is evident along the distal and palatal aspects of the root of this tooth, which is consistent with the reported history of bone grafting in this region.

Buccolingual views of tooth 21

These buccolingual cross-sectional images demonstrate that buccal cortex overlying the root of tooth 21 appears thin, but is likely intact. The contiguous palatal cortical plate appears normal and intact.

Mesiodistal views of tooth 21

These mesiodistal cross-sectional images demonstrate the presence of dense granular bone located distal to the apical two-thirds of the root of tooth 21. The bone graft material appears osseointegrated with the surrounding trabecular bone. The remaining periapical and periradicular bone appears normal, and there are no radiographic signs of endodontic pathology or a displaced root fracture in this tooth.

Normal tooth 22

Tooth 22 appears normal radiographically. The periodontal ligament space surrounding the root circumference of this tooth appear thin and uniform, and the lamina dura is intact. There are no radiographic signs of periapical or periradicular pathology. There is no evidence of a displaced root fracture.

Axial views of tooth 22

These axial cross-sectional images demonstrate that tooth 22 has a single, centrally positioned root canal. The periodontal ligament space lining the root circumference of this tooth appears thin and uniform, and the lamina dura intact. Bone graft material is evident along the mesial and buccal aspects of the middle third of the root of this tooth.

Buccolingual views of tooth 22

These buccolingual cross-sectional images demonstrate that the buccal and palatal cortical plates overlying the root of tooth 22 appear normal and intact.

Mesiodistal views of tooth 22

These mesiodistal cross-sectional images demonstrate the presence of bone graft material located along the mesial aspect of the middle third of the root of tooth 22, which appears osseointegrated with the surrounding trabecular bone. The remaining periapical and periradicular bone appears normal. There is no radiographic evidence of endodontic pathology or a displaced root fracture in this tooth.
