Chlorine dioxide flushing protocols for microbial reduction in dental chair units
Fig 2
Timeline of flushing protocols for shock disinfection processes and continuous ClO2 applications.
The figure shows the course of the individual flushing protocols and the respective disinfection measures, whereby the individual phases including stagnation are intended to reflect a real working situation in a practice. On the days indicated (flushing day), a DCU was flushed several times at hourly intervals (hour) or in a row. Each individual rhombus in the illustration corresponds to a flushing process. The flushing processes were carried out with either tap water (dark blue rhombus) or filtrated tap water (light blue rhombus). Disinfections were performed with the low ClO2 concentrations of 1.2 mg/L (A, D) and 2.4 mg/L (D), as indicated in the individual test approaches (orange rhombus), and shock disinfections are depicted as dark orange rhombus (B, C). Days of stagnation without flushing are marked as grey rhombus.
