Palatal Wound

The goal of this clinical trial is to evaluate whether two different techniques for treating palatal wounds-sutures and cyanoacrylate bioadhesive-can influence postoperative morbidity, clinical healing, and soft tissue dimensional changes in patients undergoing epithelialized gingival graft harvesting from the palate. The main questions it aims to answer are: Does the use of cyanoacrylate bioadhesive reduce postoperative morbidity compared to sutures? Does the choice of wound treatment technique affect clinical healing and three-dimensional changes in soft tissues? Researchers will compare the sutures (control group) to the cyanoacrylate bioadhesive (test group) to determine if the bioadhesive leads to improved postoperative outcomes. Participants will: Undergo epithelialized gingival graft harvesting from the palate. Receive either sutures or cyanoacrylate bioadhesive for wound closure. Be monitored for postoperative morbidity, clinical healing, and soft tissue dimensional changes.

The goal of this clinical trial is to assess the effect of Nano-biofusion gingival gel (NBF) on wound healing at the palatal donor site following soft tissue graft surgery and compare it to placebo gel. The main questions it aims to answer are: * Does NBF gel enhance wound healing after graft harvesting from the palate? * Does NBF gel reduce the number of inflammatory mediators after surgery? * Does NBF gel reduce pain and discomfort at the palatal donor site? Researchers will compare NBF gel to a placebo (a look-alike gel that does not contain the active ingredients) to see if NBF gel enhances wound healing. Study steps include: * Participants will apply the assigned gel on the surgical wound 4 times a day for 4 weeks. * Clinical photographs and measurements will be obtained on days (0, 1, 2, 4, 7, 15, 21, 30). * Wound fluid samples will be collected on days (0, 1, 2, 4, 7). * Participants will be asked about the level of pain and analgesic consumption on each follow-up visit.
