First seen Apr 23, 2026 · Last updated Jun 19, 2026 · Updated 12 times
Summary
This study tests whether adding liquid platelet-rich fibrin or low-level laser therapy to standard lip repositioning surgery can speed healing, reduce pain and swelling, and prevent the gummy smile from returning. Twenty-two adults with a gummy smile due to a hyperactive upper lip will be randomly assigned to one of the two treatments. The goal is to see which approach leads to better wound healing and longer-lasting cosmetic results.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
liquid platelet-rich fibrin and low-level laser therapy
What this could lead to
If it works, this could point toward a better way to heal and maintain results after gummy smile surgery, reducing pain and swelling.
What could go wrong
This is a very small, early-phase trial with only 22 participants, so results may not apply to everyone. The treatments are adjunctive, not a cure, and relapse may still occur.
