Effect of bovine milk on Streptococcus mutans biofilm cariogenic properties and enamel and dentin demineralization.

Purpose: The purpose of this study was to evaluate the effect of whole bovine milk on Streptococcus mutans biofilms and on demineralization of enamel and root dentin.

Methods: S mutans UA159 biofilms were cultured on enamel and dentin bovine slabs of known surface hardness (SH) and exposed (8x/day) to 10% sucrose (positive control), whole bovine milk, and 4.5% lactose.
