  1. The antimicrobial activity of three halide salts of cetylpyridinium (CPC, CPB, and CPI) against S. mutans under different culture conditions (planktonic, biofilm forming, and 24 h biofilm) was measured by IC50, MIC, and MBC in a single experiment. For each condition, no significant effect was observed for the identity of the halide counter ion within the precision of these measurements
