Effect of Cyanoacrylate Tissue Adhesive Versus Collagen Sponge on Palatal Donor Site Healing

The goal of this clinical trial is to learn if the use of cyanoacrylate glue (PeriAcryl) is effective in healing of the palatal donor site in adults requiring a free gingival graft. The main question\[s\] it aims to answer \[is/are\]: Does PeriAcryl accelerate the palatal tissue healing compared with the use of collagen sponge? Does PeriAcryl usage leave the patients more satisfied? Researcher will compare the outcomes of participants treated with PeriAcryl to those treated with collagen sponge to see if PeriAcryl accelerated the healing process of palatal tissues and led to fewer postoperative complications. Participants will: * be assigned to a study group using PeriAcryl or control group using Collagen sponge. * be followed-up to monitor healing and gather clinical information.
