Researchers at University of Saskatchewan bring a new dentist for you, who would take care of your dental problems. The dentist I am referring to is a toothbrush. Surprised? Well, dentistry professor emeritus Dr. Kunio Komiyama and his colleague Dr. Gerry Uswak have developed a prototype of light-powered toothbrush that could be the future oral hygiene. The duo has succeeded in convincing 120 teens to use their revolutionary toothbrush and will monitor the results.


Japanese company Shiken is manufacturing the world’s first high technology toothbrush called the “Soladey-J3X”. The company has hired the researchers to investigate whether the brush can eliminate plaque and bacteria more efficiently than a conventional toothbrush. The brush has a solar panel at its base that transmits electrons to the top of the toothbrush through a lead wire. These electrons react with acid in the mouth, which helps break down plaque. Hence, fighting oral problem without a toothpaste.
This one here is not the first model for Komiyama. The dentist’s first model dates back in 1995, which according to the Journal of Clinical Periodontology’s description contained a titanium dioxide rod in the neck of the brush. As light fell on the wet rod, electrons were released that reacted with acid in the mouth, breaking down plaque. The newer one is said to be an improvement over the previous model and has been tested on cultures of two types of bacteria that are major culprits in periodontal disease. The Soladey-J3X won the researches the first spot out of 170 entries at the FDI Annual World Dental Conference in Dubai last month.
