Leukocyte- and Platelet Rich Fibrin (L-PRF) Application in Impacted Mandibular Third Molar Removal Surgery

The purpose of this study was to evaluate the influence of leukocyte- and platelet-rich fibrin (L-PRF) on impacted mandibular third molar (IMTM) extraction wound healing, patient postoperative discomfort, and incidence of alveolar osteitis (AO). Thirty patients (18 female, 12 male) who met the inclusion criteria for this split-mouth study underwent bilateral IMTM surgical extractions. Following extraction, randomization was done. One socket received L-PRF, and the other socket served as a regular blood clot control. Postoperatively, the soft tissue healing index (HI), pain according to visual analog scale (VAS), facial swelling using a horizontal and vertical guide, and incidence of AO were evaluated 1, 3, 7, and 14 days after surgery.
