Antimicrobial Effect of Tropolone Containing Versus Tropolone Free Mouthwash - Randomized Clinical Trail

Early Phase 1 Interventional Cairo University · NCT03384537

This study is testing if a new mouthwash with Tropolone works better than a standard mouthwash to help keep the mouths of healthy adults free from germs that cause dental problems.

What this trial studies

This study aims to evaluate the effectiveness of a mouthwash containing Tropolone compared to a standard Chlorhexidine (CHX 0.2%) mouthwash in reducing intraoral microorganisms associated with dental diseases. It is a randomized clinical trial involving healthy volunteers aged 18 to 45 who will temporarily suspend their usual oral hygiene practices. The study seeks to address the ongoing challenge of dental caries, which affects a significant portion of the adult population in the U.S. by potentially offering a more effective mouthwash option for oral health maintenance.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy adults aged 18 to 45 with no significant dental issues.

Not a fit: Patients with compromised medical conditions or those who have recently used antimicrobial agents may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved mouthwash formulations that significantly reduce the risk of dental caries.

How similar studies have performed: While there have been studies on mouthwash efficacy, the specific comparison of Tropolone-containing mouthwash is relatively novel.
