NCT06610331

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Epithelialization

    Epithelialization of the palatal region was performed by applying 3% hydrogen peroxide to the wound area with the help of an injector, and the areas showing foaming (H2O2 bubbling) in the total surface area of the wound area were calculated as a percentage and recorded, providing information about epithelialization.

Secondary Outcomes (1)

  • wound healing

Study Arms (2)

Control Group - Free Gingival Graft

SHAM COMPARATOR
Procedure: FREE GİNGİVAL GRAFT

Test Group - Free Gingival Graft + polyvinylpyrrolidone sodium hyaluronate gel

EXPERIMENTAL
Procedure: FREE GİNGİVAL GRAFTDevice: polyvinylpyrrolidone sodium hyaluronate gel

Interventions

Free Gingival Graft removal from the palate donor area for the treatment of gingival recession

Control Group - Free Gingival GraftTest Group - Free Gingival Graft + polyvinylpyrrolidone sodium hyaluronate gel

Patients are told to gargle with a mouthwash containing polyvinyl pyrrolidone sodium hyaluronate twice a day for 2 weeks. 15 ml (1 tablespoon) of mouthwash containing polyvinyl pyrrolidone sodium hyaluronate is poured into a glass and approximately 40 ml (3 tablespoons) of water is added and mixed well, then it is shaken for at least 1 minute, making contact with the entire mouth.
