Effect of PRF Palatal Bandage on Pain Scores and Wound Healing After Free Gingival Graft

Background: Free gingival graft (FGG) is used to increase keratinized tissue dimensions. This prospective clinical trial was conducted aiming to determine whether the addition of an autologous platelet-rich fibrin (PRF) would improve soft tissue healing of donor sites and decrease pain scores. Methods: Twenty four patients were planned to receive FGG to augment keratinized tissue dimensions in the mandibular incisors area. Donor sites were assigned randomly to receive PRF or not by a flip of a coin during the screening visit. Patients were instructed to complete a pain study form. The palatal donor area were evaluated for complete wound healing records. These data were assessed and recorded before surgery, and 1,2,3,4 and 8 weeks postoperatively.
