ABSTRACT:Aim: Free gingival graft procedure is a frequently used mucogingival procedure for gingival augmentation. One of the major drawback associated with technique is healing of donor site by secondary intention which takes more time to heal and causes patient discomfort. PRF is a novel biomaterial which has shown to accelerate wound healing process. The article describes the healing of donor site with and without placement of PRF membrane in 2 patients.Case presentation: Two patients requiring gingival augmentation were enrolled for the study. The palatal donor site of one patient was covered with PRF membrane as palatal bandage. The donor site of the other patient was allowed to heal in a conventional way without PRF membrane to evaluate the difference in healing. The healing was evaluated visually by using healing index and by hydrogen peroxide test at 12th, 13th, 18th, 19th, 24th, 25th, 30th and 31st days. Palatal donor site covered with PRF membrane demonstrated considerably faster healing and higher healing score compared to site not covered by PRF membrane. Conclusion: The superior healing observed at the PRF membrane site supports its use in accelerating the soft tissue healing. PRF membrane as a bandage is an efficacious approach to protect the open wound in palate to reduce healing time and patient discomfort.
