Time-kill curves for P. gingivalis JCM12257 (a) and A. actinomycetemcomitans JCM8577 (b) following exposure to 0.9% NaCl (control), 0.2% CHX, and NBW3. The number of CFUs/mL of P. gingivalis exposed to 0.2% CHX did not drop to below the lower limit of detection (<10 CFUs mL−1) until 5 min of exposure. In contrast, the number of CFUs/mL of P. gingivalis exposed to NBW3 dropped to below the lower limit of detection (<10 CFUs mL−1) after only 0.5 min of exposure. Also, the number of CFUs/mL of A. actinomycetemcomitans exposed to NBW3 and 0.2% CHX dropped to below the lower limit of detection (<10 CFUs mL−1) after 0.5 min of exposure.
