The future of Oral hygiene could be Solar! Imagine not having to squeeze out the last bit of toothpaste from the tube! Worrying about your spouse not closing it properly… Not having to write a note to pick up the right brand (with the wide variety out there finding the right paste is almost an adventure in itself J University of Saskatchewan Dentistry professor Emeritus Dr. Kunio Kumiyama and his colleague Dr. Gerry Uswak were recruiting 120 teens willing to try out the solar powered toothbrush Soladey-J3X in 2007. The Japanese manufacturer The Shiken Company is paying the researchers to investigate whether the brush, which causes a chemical reaction in the mouth works better on plaque than a conventional brush and toothpaste combo.
Dr. Kumiyama described his first prototype 15 years back in the Journal of Clinical Periodontology. It contained a titanium dioxide rod in the head of the brush just beneath the nylon bristles. When light shined on the wet rod it would release electrons which reacted with the acid in the mouth which helped breakdown the plaque without using toothpaste.
Now the latest edition the Soladey-J3X according to Dr. Kumiyama packs double the chemical punch when compared to the earlier version. Protruding from the base of the brush is a solar panel, which transmits electrons to the top of the toothbrush through a lead wire. For the brush to work one needs ambient light, i.e. light enough for a solar powered calculator to work.
How Does it Work?
The brush holder head lasts for a long time, while the head will need replacement when the bristles fray. The brush heads are priced at around 250 yen (3$) in Japan.
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.
