Solar toothbrush could make toothpaste obsolete

SASKATOON -- Toss the toothpaste. The future of oral hygiene is solar.

University of Saskatchewan dentistry professor emeritus Dr. Kunio Komiyama and his colleague Dr. Gerry Uswak are recruiting 120 teens willing to brush with a prototype light-powered toothbrush and sit in a dentist's chair for a few extra inspections.

The manufacturer, the Shiken company of Japan, is paying the researchers to investigate whether the brush, which causes a chemical reaction in the mouth, does a better job of eliminating plaque and bacteria than a conventional toothbrush.
