The double-blind study had 64 adult subjects ranging in age from 18 to 67 years. The control group, Group 2, had 34 subjects using the hyG Ionic Toothbrush without an active battery. The mechanism for the ionic action is due to a change in the polarity of the teeth. The tooth is normally negatively charged and the plaque is positively charged.
Opposite charges attract and bond to each other.
The battery is similar to a watch battery and just as safe. The toothbrush bristles are negatively charged through the metal rod with the brush head. When holding the metal band on the toothbrush handle with moistened fingers, the positively charged ions are transferred to the teeth. The tooth polarity changes from negative to positive. The positively charged tooth ions repel the positively charged plaque ions.
