Combined Effects of Xylitol and a Low Concentration of Fluoride on Promotion of Remineralization of Human Enamel, an Experimental Study.

The purpose of this study is to evaluate the combined effects of xylitol and low concentrations of fluoride on the promotion of remineralization of human enamel. Demineralized enamel blocks were immersed in remineralizing solutions containing 10% xylitol and various concentrations of fluoride (0-1.2ppm). The remineralizing solution containing xylitol and fluoride was found to promote remineralization between 14 and 15 degrees of saturation with respect to fluoroapatite. Although both fluoride and xylitol are thought to promote remineralization, from this study, it can be suggested that for effective remineralization, the degree of saturation with respect to fluoroapatite should also be considered.
