Canadian researchers have designed a toothbrush that cleans teeth by creating a solar-powered chemical reaction in the mouth, doing away with the need for toothpaste, said physorg.com.
Dr Kunio Komiyama, a dentistry professor emeritus at the University of Saskatchewan, designed the first model of the unconventional toothbrush 15 years ago. Today, Komiyama and his colleague Dr Gerry Uswak are seeking recruits to test their newest model, the Soladey-J3X.
The toothbrush, which is manufactured by the Shiken company of Japan, will soon be tested by 120 teenagers to see how it compares to a normal toothbrush.
The Soladey-J3X has a solar panel at its base that transmits electrons to the top of the toothbrush through a lead wire. The electrons react with acid in the mouth, creating a chemical reaction that breaks down plaque and kills bacteria.
The toothbrush requires no toothpaste, and can operate with about the same amount of light as needed by a solar-powered calculator.
Last month, the researchers presented their research at the FDI Annual World Dental Conference in Dubai, where their poster won first prize out of 170 entries.

Solar toothbrush doesn't need toothpaste

Wow, that's cool. What's next? Perhaps solar-powered floss? Seriously, though, that seems like a pretty neat invention for being able to destroy the bacteria in your teeth without a toothpaste. Of course, you still need to keep your teeth clean with dental floss and mouthwash. And remember to visit your dentist regularly, to make sure your teeth are one-hundred percent clean.
