NCT ID NCT07355673
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two ways to protect gums during in-office teeth whitening: relative isolation (using a tray) and absolute isolation (covering gums completely). Thirty healthy adults with no cavities or gum disease took part. Researchers checked for gum irritation, tooth sensitivity, and how well the whitening worked.
