Objective:
To assess the anti-gingivitis and anti-plaque efficacy of a novel bioavailable stannous fluoride (SnF2) dentifrice to a negative control.
Methods:
This was a 12-week randomized, controlled, double-blind, two-treatment, parallel group clinical study. One hundred generally healthy adults with evidence of plaque and gingivitis were enrolled into the study. Subjects were randomly assigned to one of two dentifrice treatments: (1) novel SnF2 dentifrice containing the amino acid glycine as a stabilizing chelant (Procter and Gamble) or (2) a negative control sodium monofluorophosphate dentifrice. Gingivitis was assessed using the Löe-Silness Gingivitis Index (LSGI) at baseline, Week 1, and Week 12 while plaque was evaluated according to the Turesky Modification of the Quigley-Hein Plaque Index at baseline and Week 12.
Results:
One hundred subjects completed the trial. Subjects using the novel SnF2 dentifrice demonstrated statistically significantly fewer bleeding sites and a lower LSGI score versus those using the negative control as early as Week 1 (P less than .001). The benefit increased throughout the study, with the SnF2 dentifrice showing 33.4% fewer bleeding sites and a 16.5% lower LSGI score versus the negative control at Week 12 (P less than .001). Subjects with localized or generalized gingivitis (≥10% bleeding sites) had 6 times better odds of transitioning to generally healthy (less than 10% bleeding sites) after using the SnF2 dentifrice for 12 weeks versus the negative control. Plaque scores for the SnF2 dentifrice were also statistically significantly lower (P less than .001) than those for the negative control at Week 12.
Conclusion:
The novel SnF2 dentifrice with the amino acid glycine produced statistically significant improvements in gingival health that were seen as early as 1 week and numerically increased throughout the study.
