Evaluating hop extract concentrations found in commercial beer to inhibit Streptococcus mutans biofilm formation.

Aims: The purpose of this study was to compare the effect of hop extracts with diverse β-acid concentrations on Streptococcus mutans biofilm formation.

Methods And Results: Ten different hop extracts, with α-acid concentrations similar to those found in commercial beer products and β-acid concentrations ranging from 2.6 to 8.
