Chinese scientists have created a toothbrush that generates a current to fight bacteria.
Peking University has developed a self-charging toothbrush without batteries, which generates electricity during the cleaning process and destroys bacteria, reports Kazinform's own reporter.
Unlike traditional models that use exclusive mechanical friction, the device is equipped with bristles made of "smart" plastic. When it is twisted, the material produces microcurrents, which, in contact with water in the oral cavity, create antibacterial compounds.
During three months of tests involving 115 volunteers, the development reduced plaque by 40% compared to 15% for conventional brushes, and also reduced gingivitis. Additional long-term follow-up is required for market entry.
