A comparative pilot study of the effects of a dentifrice containing green tea bioflavonoids, sanguinarine or triclosan on oral bacterial biofilm formation.
The aim of the present study was to evaluate the effect of a green tea bioflavonoid/zinc ascorbate-containing dentifrice (Natural Antioxidant Toothpaste) on bacterial plaque biofilm accumulation. Plaque biofilms were formed and observed on saliva-conditioned synthetic hydroxyapatite disks (HA) over 4 days. Two test treatments were performed daily over a 4-day experimental period for a total of 8 treatments. Four test dentifrices were evaluated: a 0.1% bioflavonoid/0.2% zinc ascorbate; a non-active control test dentifrice; a 0.075% sanguinarine/2.0% zinc chloride dentifrice; and a 0.3% triclosan dentifrice. The repeated treatment of the HA with the green tea bioflavonoid/zinc ascorbate, the sanguinarine/zinc chloride, or the triclosan dentifrice resulted in significant reductions in total viable plaque biomass when compared to a non-active placebo control dentifrice.
