Plasma Sterilization Effectively Reduces Bacterial Contamination in Dental Unit Waterlines

Figure 1

(a) Total bacterial count from dental chair unit input water. Each line indicates the average CFU/mL at different time points. The blue line represents the average CFU/mL from input water of the PSS group. The red line represents the average CFU/mL from input water of the control group. The average number of the bacterial count in CFU/mL is presented in the table below the chart. (b) The average CFU/mL of the entire period of the experiment. The bacterial count of input water of the two groups is not significantly different.
