Figure 2

Boxplots depicting the bacterial count of surviving anaerobic colony forming units (CFUs) determined after 1 min and 3 min treatments with 0.2% CHX digluconate in the different groups: centrifuged bacteria and 0.2% CHX in saliva without ethanol, centrifuged bacteria and 0.2% CHX in saliva with ethanol, centrifuged bacteria and 0.2% CHX in NaCl without ethanol, centrifuged bacteria and 0.2% CHX in NaCl with ethanol. The medians and whiskers are displayed. The whiskers depict the range between minimum and maximum values. n = 20, *p ≤ 0.01 (Tukey-Kramer). The statistical significance regarding the bacterial counts was high (p ≤ 0.001) between each of the tested groups and the baseline.
