It seems that the world's first treatment device that kills 99.99% of periodontal disease has been developed by the president of “Luke” and professor of Tohoku University Graduate School of Dentistry.
This treatment device is said to be able to kill 99.99% of bacteria that cause periodontal disease as well as dental plaque by irradiating a blue laser while vibrating with ultrasonic waves.
