The Effectiveness of the Improved NaHPO4-SnF2-ZrSiO4-SiO2 Prophylactic Paste.
Abstract
The purpose of this study is to investigate in-vivo enamel solubility techniques the effect of aging on Zirconium Silicate-Stannous Fluoride Prophy Paste. Stannous fluoride is an agent which has been used in solutions, dentifices and prophylactic pastes to reduce the incidence of dental caries and there is little doubt that SnF2 is effective in reducing dental caries. However, there is evidence to suggest that aging decreases SnF2 compound's ability to reduce enamel solubility. The reduction in effectiveness of SnF2 compounds is explained in part by the oxidation of stannous Ion to the stannic ion. It has also been suggested that this stannic ion precipitation may have some effect on the fluoride ion. It is for this reason and others that dentists and dental scientistis recommend that freshly made SnF2 solutions be used for maximum effectiveness. This is also the reason that a reservoir of SnF2 ions is incorporated into crest toothpastes and SnF2 prophy pastes.
