Periapical surgery is required when periradicular pathosis associated with endodontically treated teeth cannot be resolved by nonsurgical root canal therapy (retreatment), or when retreatment was unsuccessful, not feasible or contraindicated. Endodontic failures can occur when irritants remain within the confines of the root canal, or when an extraradicular infection cannot be eradicated by orthograde root canal treatment. Foreign-body responses toward filling materials, toward cholesterol crystals or radicular cysts, might prevent complete periapical healing. We present here a case report wherein, combination of platelet-rich fibrin (PRF) and the hydroxyapatite graft was used to achieve faster healing of the large periapical lesion. Healing was observed within 8 months, which were confirmed by computed tomography, following improved bone density. PRF has many advantages over platelet-rich plasma. It provides a physiologic architecture that is very favorable to the healing process, which is obtained due to the slow polymerization process.
