First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study tests four ways to remove dark spots (hyperpigmentation) from gums: laser, two types of air polishing with powder, and traditional surgical cutting. The goal is to see which method works best and causes the least discomfort. Participants are healthy adults aged 18 to 50 who want treatment for gum pigmentation.
