Palatal Wound Healing Evaluation After Application of Platelet Rich Fibrin Versus 0.2% Hyaluronic Acid Dressings

Free gingival graft (FGG) was first proposed by Bjorn 1963 and Nabers 1966. FGG is indicated to correct mucogingival problems such as inadequate or lack of attached gingiva and gingival recession. The most frequent donor site for free gingival graft is the palate Although, great concern has been given to the recipient sites by using different techniques as suturing, tissue adhesives and special dressings, a little attention was given to protect the donor sites after free gingival graft harvesting. The palatal donor site heal by secondary intention, it could take around 2 to 4 weeks depending on the width and thickness of the tissue removed.The common clinical events that occurs following FGG procedure are patient's discomfort, pain and bleeding at the donor site.
