Active Oxygen Gel Versus Hyaluronic Acid Gel for Palatal Wound Healing After Free Gingival Graft

This randomized controlled clinical trial aims to evaluate and compare the effectiveness of different palatal dressing materials on wound healing following free gingival graft harvesting. Thirty systemically healthy patients with mucogingival defects requiring free gingival graft procedures will be enrolled from the outpatient clinic of the Department of Oral Medicine and Periodontology, Faculty of Dentistry, Suez Canal University. Patients will be randomly allocated into three equal groups (10 patients each). Group A (control) will receive a gelatin sponge with flowable composite on the donor site. Group B will receive hyaluronic acid gel covered with a gelatin sponge and flowable composite. Group C will receive active oxygen gel covered with a gelatin sponge and flowable composite. Postoperative outcomes will be assessed in terms of pain (visual analog scale), analgesic consumption, clinical wound healing (Landry healing index), complete wound re-epithelialization (hydrogen peroxide test), dimensional changes of the wound, and occurrence of complications. Evaluations will be performed at baseline and during follow-up visits up to four weeks postoperatively. The study aims to determine which dressing material provides better postoperative comfort and enhances palatal wound healing after free gingival graft procedures.
