About

The aim of this clinical study was to evaluate the effect of polyvinylpyrrolidone sodium hyaluronate gel on palatal wound healing, pain, and bleeding after free gingival graft surgery. This study included 32 systemically healthy patients who required free gingival graft surgery. After the operation, the test group received polyvinylpyrrolidone sodium hyaluronate gel in addition to chlorhexidine gluconate mouthwash, whereas the control group received only chlorhexidine gluconate mouthwash. VAS scale was used to evaluate palatal pain, burning, and chewing discomfort, WHI was used to evaluate wound healing, and H2O2 foaming test was used to evaluate epithelialization. VAS and bleeding values were recorded on postoperative day 1; VAS, WHI, H2O2, and bleeding values on postoperative days 3, 7, and 14; and WHI, H2O2, and bleeding values on postoperative day 28.
