Definition : Toothbrushes designed to perform mechanical and ultrasonic cleaning of teeth. These toothbrushes clean the teeth with a simultaneous mechanical motion (e.g., back-and-forth, circular, elliptical) and an ultrasonic wave action when manually placed on the teeth by the user. Ultrasonic toothbrushes typically include a set of bristles arranged in a rectangular or circular array, an ultrasound transducer, and a handle that includes an electric motor and batteries. Ultrasonic toothbrushes are usually reusable battery-powered devices.
