NCT ID NCT07669636
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This lab study tests whether adding N-acetylcysteine and hyaluronic acid to a standard chlorhexidine mouthwash can reduce harm to gum cells. Researchers will grow human gum cells from discarded dental tissue and expose them to different mouthwash strengths. They will measure cell survival, movement, and gene activity to see if the new formula is less toxic.
