NCT00471783

Brief Summary

To determine if flossing with a dental floss presoaked in chlorhexidine, an anti-microbial mouth wash, would improve the clinical signs of gingivitis, an inflammation of the gums characterized by red, swollen, bleeding gums. And to determine if applying chlorhexidine via dental floss would result in tooth staining, which is common with chlorhexidine mouthwashes.
