(A-G) Representative images of CFU of bacteria survived on the surface of dentine slices after treated. A NG, B 0.5 µg/mL CPC, C 80 µg/mL AgNO₃, D 2% CHX; E 0.5 µg/mL CPC + 80 µg/mL AgNO₃, F 0.5 µg/mL CPC + 40 µg/mL AgNO₃, G 0.25 µg/mL CPC + 80 µg/mL AgNO₃. H The CFU counting result of each group. NG: negative control group. As compared with NG or inter-groups: ns: no significant difference, *: p < 0.05, ****: p < 0.0001
