Data are presented as mean lg (CFU/mL + 1) ± standard deviation. Ar: argon; CHX: 0.1% chlorhexidine; OCT: 0.1% octenidine; PHMB: 0.1% polyhexanide; NaOCl: 0.6% sodium hypochlorite; H2O2: 1.5% hydrogen peroxide; EDTA: 20% ethylenediaminetetraacetic acid. Entries with the lowest CFUs/mL were boldface font. versus NaCl control (within columns); ** versus control procedure (within rows); # Ar plasma versus Ar gas (within rows), two-sided Mann-Whitney U tests, and reduction in respective CFUs/mL. P values were Bonferroni corrected. |
