NCT05821725

Brief Summary

This clinical study aims to investigate the impact of a topical hyaluronic acid (HA) gel on postoperative pain and wound healing at palatal donor sites in patients undergoing mucogingival procedures involving a de-epithelialized gingival graft (DGG) from the palate. The study design is a Phase III, randomized, double-blind, parallel-group, clinical trial, conducted in a single center, with 30 subjects aged 18-70 years.
