Six-year histology of an avulsed molar reimplanted in a hydroxyapatite augmented socket: a case report.
This case report deals with the histologic examination of an avulsed tooth that was reimplanted in a socket where a distal root defect was augmented with hydroxyapatite. The 6-year results showed a "repair" type of connective tissue attachment. There were areas of ankylosis present on the distal root above an area of prior cystic debridement. The hydroxyapatite particles present demonstrated biocompatibility and encapsulation by new bone growth. There was a longer junctional epithelium present on the distal root than on its mesial counterpart. Histology of the distal root demonstrated fibrous repair, ankylosis, and osseous formation around the hydroxyapatite particles. This type of result was not apparent on the mesial root, devoid of hydroxyapatite, where a "splicing" type of healing occurred in the periodontal ligament.[1]References
