An in vitro study of the effect of fluoridated milk on oral bacterial biofilms

Microcosmic dental plaques were grown in artificial saliva and supplemented with either milk or fluoridated milli. The presence of fluoride in the mil k increased the pH of the biofilms and reduced the proportions of streptoco cci, demonstrating that in this model, fluoridation of milk produces biofil ms with reduced cariogenic potential.
