Fig. 1From: Enhanced in vitro antibacterial effect against Enterococcus faecalis by using both low-dose cetylpyridinium chloride and silver ionsAntibacterial efficiencies of different concentrations of CPC + Ag+ against planktonic E. faecalis for 24 h. Compare the bacterial CFU counts among NG with tested groups (n = 6). NG: negative control group (E. faecalis without treatment). As compared with NG or inter-groups, ns: no significant difference, *: p < 0.05Back to article page
