NCT00743548

Brief Summary

The study's purpose is to find an easy and effective alternative to dental floss for those persons who cannot or choose not to dental floss so that they can maintain and/or achieve optimal oral health. The study hypothesis is that the inter-dental brush is as effective as dental floss for removing plaque from between the teeth and for reducing bleeding gums in persons with gingivitis, but may be easier to use and thus encourage daily home use.

ACTIVE COMPARATOR

Interdental brush (IB), the intervention is a small multi-tufted brush on a wire attached to a long angled handle that is inserted in a horizontal plane between the teeth. The IB is inserted once and removed.

Device: IB = Interdental brush, the intervention

2

PLACEBO COMPARATOR

Dental floss (DF), the positive control, is waxed dental floss; nylon covered with a water soluble unflavoured wax to facilitate easier access the contact points of teeth. DF is rubbed against the interproximal surfaces of the teeth 2-4 times on each surface.

Device: DF = Dental floss, the positive control
