STUDY OF HYALURONIC ACID USED WITH GUM SURGERY TO TREAT GUM RECESSION IN ADULTS

Sponsor: Universidade do Porto

Summary

Gingival recession is a common condition in which the gum tissue recedes, exposing the root surface of the tooth. This can lead to tooth sensitivity, higher risk of root decay, and aesthetic concerns. A commonly used surgical treatment is the coronally advanced flap combined with a connective tissue graft (CAF + SCTG), which aims to cover the exposed root and improve gum health. Hyaluronic acid (HA) is a naturally occurring substance in the body that plays an important role in wound healing. It may help improve tissue repair, reduce inflammation, and enhance healing after surgery. This study aims to evaluate whether the use of hyaluronic acid (hyaDENT BG®) in addition to standard surgical treatment improves clinical outcomes in patients with gingival recession. Participants will be randomly assigned to receive either standard treatment alone or standard treatment with hyaluronic acid. The main outcome is the proportion of sites with complete root coverage after 12 months. Additional outcomes include healing, gum tissue improvement, patient-reported pain and discomfort, and aesthetic results. The study also includes a laboratory component to investigate how hyaluronic acid affects cells involved in gum healing.
