The Effectiveness of Different Methods for Healing a Palatal Donor Site

Postoperative complications associated with free gingival graft (FGG) procedures are prolonged bleeding from the donor site, postoperative pain and delayed wound healing which increases the patients\' morbidity. Hence, the aim of this study is to assess the effectiveness of different treatment modalities on palatal wound healing and patient\'s morbidity after FGG. Ninety patients requiring FGG were randomly will be assigned into six groups: group 1: Platelet rich fibrin (PRF) membrane, group 2: Essix retainer, group 3: topical ozone therapy, group 4: low-level laser therapy (LLLT), group 5: collagen fleece and group 6: untreated control group. Epithelization will be evaluated by means of bubble formation; sensitivity, edema, pain, changes in eating habits and burning sensation will be assessed by using visual analog scale (VAS) and also the presence of discomfort and bleeding will be evaluated in the postoperative first week and at 14 days, 1 and 3 months postoperatively.
