Electrolyzed Strong Acidic Water as a New Harmless Disinfectant Agent and its Application to Dentistry

概要

For exerting a disinfectant effect, electrolyzed strong acidic water should maintain such properties as the oxidation-reduction potential being 970 mV or greater, the concentration of active chlorine gas 0.8 ppm or higher, and pH 2.7 or less. It was found that when fresh samples of electrolyzed strong acidic water are stored in a tightly closed container that protects them from light, no change occurred in 2 weeks and its disinfectant efficacy did not change for about 1 month if the storing temperature was kept as about 4°C. Since salivary proteins largely affect the property of electrolyzed strong acidic water in its oral use, it is necessary to minimize the weakening of the oxidation-reduction potential and the concentration of active chlorine gas by increasing frequency of mouthwashing. Despite the presence of salivary proteins at ordinary concentrations, electrolyzed strong acidic water showed excellent disinfectant effects not only on <I>Streptococcus mutans</I>, a bacterial species relating most closely to dental caries, but also on <I>Candida albicans</I>, a main fungus species forming denture plaques.
