Plaque inhibition and improved gingival condition by use of a stannous fluoride toothpaste.

The present study contains data from a 4-week clinical study where the effect of an experimental toothpaste containing 0.4% SnF2 on plaque and gingivitis was tested in a group of teenagers. The study was performed according to a double-blind, cross-over design. It was shown that the SnF2 containing toothpaste reduced both plaque and gingivitis significantly compared to a placebo paste which contained no fluoride or stannous ions.
