- Oral rinse samples from five healthy volunteers were exposed to mouthrinse formulations (final concentration, 5 % v/v) containing CPC (TR) or CPC and fluoride (TFR). Control rinses without CPC (CR and CFR, respectively) and a treatment-free control (NTC) were also included. Mean viable count data are shown. Both test rinses caused significant reductions in viability compared to their respective controls in samples from five volunteers (*, p < 0.05, n = 5). na, not applicable
