Chlorine dioxide flushing protocols for microbial reduction in dental chair units
Fig 5
Correlation of the total cell counts (TCC), the intact cell counts (ICC) and the ClO2 concentration during the study period.
According to the flushing protocol (Fig 2D), the DCU was flushed at indicated days either with tap water (blue line) or with ClO2 solutions (orange line) at initial concentrations of 1.2 mg/L (A) and 2.4 mg/L (B). Total cell counts (TCC; grey columns) and intact cell counts (ICC; black columns) were calculated alongside the ClO2 concentrations (dotted line), determined using the Palintest, either from the syringe (upper diagram) and from the cup filler (lower diagram). Each column (mean value ± standard deviation) represents the flushing day and hour according to Table 4.
