Summary
This study tests whether applying citric acid during a procedure to remove dark gum pigmentation leads to better-looking results and faster healing. Adults aged 18 to 50 with natural dark gums will receive either standard depigmentation or depigmentation plus acid. The researchers will compare esthetic improvement, pain, and how long the results last.
