How long does it take to disinfect with chlorine dioxide?

Typically, chlorine dioxide is used at a concentration of 25-50 parts per million (ppm) with 2 to 4 minutes of contact time for sanitizing calf feeding equipment, and at a concentration of 250-500 ppm with 5 to 10 minutes of contact time for disinfecting facilities and calf pens.

Why is chlorine dioxide in mouthwash?

Chlorine dioxide reduces both plaque and gingival indices and bacterial counts in the oral cavity similar to other routinely used oral rinses, however, the evidence supporting this outcome is very limited. Therefore, further large scale RCTs are needed to decrease the risk of bias.

What Is Chlorine Dioxide?

Is chlorine dioxide mouthwash better than chlorhexidine?

Results: Chlorhexidine inhibited plaque growth significantly more than the mouthrinse containing chlorine dioxide (plaque index = 1.39 versus 1.96, respectively; P <0.001). The results of the questionnaire showed that the panelists found chlorhex- idine easier to use and more effective.
