Solar-powered toothbrush requires no toothpaste

Solar-powered toothbrush green gadgetFor now on you can travel without any worries. No matter if you forgot the toothpaste; most important thing is to take your toothbrush powered by solar energy. Another green gadget is tested in the pre-market phase.


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.

The researchers have already tested the toothbrush in cultures of bacteria that cause periodontal disease, and demonstrated that the brush causes “complete destruction of bacterial cells,” Komiyama said. Their research project was showed at the FDI Annual World Dental Conference in Dubai, where their poster won first prize out of 170 entries.
