NCT ID NCT07563413
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether charcoal-infused toothbrushes remove plaque and stains better than regular nylon toothbrushes. Thirty-six Egyptian adults brushed twice daily for 4 weeks with standard toothpaste. Plaque and stain levels were measured at the start and end. The goal is to see if the charcoal brush offers any real advantage for everyday oral hygiene.
