This study investigated the antibacterial effect of electrolyzed water on oral bacteria both in vitro and in vivo. Tap water was electrolyzed in a water vessel using platinum cell technology. The electrolyzed tap water (called Puri-water) was put in contact with five major periodontopathogens or toothbrushes contaminated with these bacteria for 30 sec. In addition, Puri-water was used as a mouthwash for 30 sec in 16 subjects and the antibacterial effect on salivary bacteria was evaluated. Puri-water significantly reduced the growth of all periodontopathogens in culture and on toothbrushes, and that of aerobic and anaerobic bacteria in saliva, when compared to the effect of tap water. It also significantly reduced mutans streptococci growing on mitis salivarius-bacitracin agar. Our results demonstrate that the electrolyzed tap water is effective as a mouthwash and for toothbrush disinfection.

Editor’s note: “Electolyzed tap water” is another name for ionized water. In this case, they are using ionized acidic water to kill bacteria in the form of mouthwash and toothbrush sterilization. We use Chason ionized acidic water to do both on a regular basis! Think how much money you would save if you never had to buy another bottle of mouthwash again! With a Chanson water ionizer, you won’t have to! And oral health care is only one of the many uses of Chanson ionized acidic water, see the more complete list here.
