ABSTRACT
Aim- Rationale of surgical endodontics is to remove the diseased tissue present in the canal and around the apex, and retrofill the root canal space with biologically inert material so as to achieve a tight seal.
Methods and Materials– A periapical endodontic surgery was performed in the upper front teeth region. The surgical defect was filled with a combination of platelet rich fibrin membrane with demineralized freeze dried bone allograft and hydroxyapatite bone graft. Non-vital tooth bleaching procedure was carried after 3 months with hydrogen peroxide.
Result- Clinical examination revealed good wound healing. Radiologically graft material was replaced by bone formation at the end of 9 months.
Conclusion- On the basis of the results obtained in our case report, we hypothesize that use of PRF in conjunction with two different types of bone grafts might have induced the rapid rate of bone formation.
Key words: Platelet rich fibrin, bone graft, periapical lesion, bleaching.
