Postoperative pain and bleeding are the most common complications after palatal graft harvesting, also postsurgical swelling have been reported. Although hemostatic agents, mechanical barriers, bioactive materials, antibacterial and antiseptic agents and herbal products have been found effective in preventing such complications, an ideal support could not be specified for this purpose. Further, undesired side effects such as delayed wound healing/foreign body reaction have been reported .~No gold standard has been identified, thus there is a need for further investigations aiming to reach the best possible treatment modality for pain relief and prevention of reported complications following harvesting of palatal graft .
The aim of the study is to evaluate the effect of application of Alvogyl versus hyaluronic acid in decreasing postoperative pain and promoting healing in the palatal wound following the free gingival graft procedure
