Gum color survey: no treatment, just observation
NCT ID NCT07316205
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study measured the amount and type of dark coloring (pigmentation) on the gums of 70 healthy Egyptian adults. Researchers used standard dental scales to record how widespread and how dark the pigmentation was. The goal was simply to describe normal gum color patterns in this population, not to test any treatment.
