Effects of PVP-Iodine pH and Calcium Concentration on Fluoride Varnish Anti-Caries Efficacy In Vitro

Conclusion: PVP-iodine pre-treatments can be modified to enhance the rehardening and fluoridating effect of fluoride varnishes, thereby potentially improving their ability to prevent caries in vivo. Although numerical differences between groups were small, the addition of high concentrations of calcium paired with a low pH appears most favorable under the present conditions.
