Toothbrush showdown: which brush beats plaque best?
NCT ID NCT06565897
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed Phase 2 study enrolled 84 adults with mild to moderate plaque and gingivitis. Participants were randomly assigned to use one of two manual toothbrush and toothpaste regimens at home for 6 weeks. Dentists measured plaque and gum inflammation at 1, 3, and 6 weeks to see which regimen worked better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- manual toothbrush and toothpaste
- What this could lead to
- If successful, this could confirm that a specific toothbrush and toothpaste combination is more effective at reducing plaque and gum inflammation than another.
- What could go wrong
- This is a small, completed Phase 2 study with only 84 participants, so results may not apply to everyone. Also, it tests a common product, so any benefit is likely modest.
