New mouthwash ingredient takes on dental germs in tiny trial
NCT ID NCT03384537
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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 lead to
- If it works, this could point toward a gentler alternative to chlorhexidine for controlling dental bacteria.
- What could go wrong
