Latest Invention: Soladey-J3X - Toothbrush that Doesn't Need Toothpaste


A team of researchers led by Dr. Kunio Komiyama, a dentistry professor emeritus at the University of Saskatchewan in Saskatoon, Saskatchewan, Canada, has invented a toothbrush that makes a solar-powered chemical reaction in a person's mouth to clean their teeth.

With their latest invention, researchers can eliminate the need to use toothpaste. Currently Komiyama and his colleague Dr. Gerry Uswak are searching for volunteers to test their new toothbrush, dubbed the Soladey-J3X.

Manufactured by a Japan-based company the Shiken, the latest invention is to be tested by 120 youngsters.

It is worth mentioning that the Soladey-J3X uses a solar panel installed at its base to send electrons to the top of the toothbrush via a lead wire. The electrons then come into reaction with acid in the mouth, thus leading to a chemical reaction that not only breaks down plaque but also kills bacteria.

In June, the researchers unveiled their latest invention at the FDI Annual World Dental Conference in Dubai, where they managed to win first prize out of 170 entries, informs Physorg.
