This in vitro study assessed the antibacterial effect on Streptococcus mutans biofilms of mouth rinses with 700 ppm F- (derived from NaF) that differed only in their acid compounds (malic (A), citric (B), tartaric (C), fumaric (D), hydrochloric (E), phosphoric (F), and lactic (G) acid) used to adjust pH. S. mutans (ATCC 25175) was grown for 22 h at 37°C, harvested, resuspended in simulated body fluid and biofilm formation followed for 24 h at 37°C. Thereafter, biofilms were treated with experimental rinses for 30 s, and placed in TAM48 isothermal microcalorimeter at 37°C for 72 h...
