Palatal Donor-Site Healing and Patient-Reported Outcome Measures Following Chitosan and Injectable Platelet-Rich Fibrin-Enriched Chitosan Application Compared with Gelatine Sponge: A Three-Arm Randomised Controlled Clinical Trial.

Researchers compared three dressings for palatal donor sites after graft harvesting: chitosan-enriched with platelet-rich fibrin, chitosan alone, and gelatine sponge. Both chitosan groups showed faster healing and better colour match, with the enriched version reducing early pain and dietary disruption more effectively.
