The University of Saskatchewan has been conducing clinical trials on its solar-powered toothbrush. The uniqueness of this brush is that it converts light to plaque-busting electrons. The university is currently gaining international recognition towards running these clinical trials.
At a global dental expo held in Hong Kong, dental students K.Y.J.Li and J.H. Lee won the third place towards a poster presentation. This project involved the testing of their Soladey-J3X toothbrush for converting solar energy into the electrons towards helping in breaking up plaque. It is more effective when compared to the regular toothbrush in terms of reducing bleeding that is associated with gingivitis.
Though this toothbrush is a solar-powered one, the battery is actually not charged by the sun. A solar panel present on the brush converts light into electrons. These electrons go on to interfere with dental plaque present in the user’s mouths towards destabilizing it while making it easier for removing and killing plaque bacteria.
