Platelet-rich plasma and platelet-rich fibrin in oral surgery: A narrative review.

Platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) are biological products derived from the plasma fraction of autologous blood that have a platelet concentration above that of the original blood. Cytokines and growth factors are present in platelet-based preparations, and their application has gained great attention in dentistry. The aim of this review was to comprehensively examine the latest scientific evidence on the use of PRF and PRP in oral surgery, and to describe current operational protocols. Platelet-rich fibrin is used after third molar extractions, in the treatment of alveolar osteitis and trismus, and in implant surgery. Platelet-rich plasma is utilized in sinus lift procedures, after tooth extractions, and in patients undergoing the treatment of bisphosphonate-related osteonecrosis of the jaw. Based on this review, plenty of data indicates that the PRF-PRP usage in oral surgery shows promising results. However, no consistent protocols have been presented in the analyzed articles. Further research is needed to provide clinicians with evidence-based clinical recommendations and to develop protocols on the use of these preparations in dental surgery.
