NCT ID NCT03384537
First seen Mar 30, 2026 · Last updated Jun 23, 2026 · Updated 11 times
Summary
This early study compares a mouthwash containing tropolone to the standard chlorhexidine 0.2% mouthwash for reducing bacteria that cause cavities. Thirty healthy adults aged 18–45 will stop their usual oral hygiene for a few days, then use one of the mouthwashes. Researchers will measure bacterial counts to see if tropolone works as well as chlorhexidine.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
tropolone-containing mouthwash
What this could lead to
If it works, this could point toward a gentler alternative to chlorhexidine for controlling dental bacteria.
What could go wrong
This is a very small early-phase study with only 30 people, so results may not apply widely. It also does not test long-term safety or effectiveness.
