Interactions of zinc with fluoride on growth, glycolysis and survival of Streptococcus mutans GS-5.

abstract：:The purpose of this study was to determine the efficacy of fluoride varnish (FV) in inhibiting progression of secondary caries (SC). In a first experiment, human teeth, restored either with amalgam or resin composite, were exposed for 4 days to a microbial caries model. Half of each specimen was then painted with an a...

abstract：:Fluoride is a well-studied and widely used agent for the prevention of dental caries. Although dental caries is strongly related to cariogenic biofilms, the effect of brief fluoride treatment on the virulence properties of biofilms has not been well studied. This study evaluated the effect of a 1-min fluoride treatmen...
