Abstract
An ultrasonic toothbrush for use in personal dental hygiene care includes an elongated handle member in the form of a hollow housing having disposed therein a low voltage coil and cooperating ferrite core which is driven at ultrasonic frequencies. Affixed to the core is a brush member adapted to be received within the human mouth and moved across tooth and gingival surfaces. The brush member has been adhesively affixed to an impedance transfer device which in turn has been adhesively affixed to the core material. The impedance transfer device insures the maximum transfer of ultrasonic energy from the core material to the brush. The ultrasonic energy driving means for the core requires a relatively low voltage and permits the coil to be sealed in the handle impervious to contamination by water.
