Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the problem that an optimal washing part and the depth of massage are fixed since ultrasonic waves from a plate-like piezoelectric vibrator is emitted in a single direction and has vibration of a single frequency in an ultrasonic gum massager. SOLUTION: Regarding this oral hygiene apparatus, a cylindrical-type ultrasonic vibrator is mounted to an ultrasonic emitting part, and the ultrasonic vibrator emits ultrasonic vibration of three frequencies consisting of diameter vibration, thickness vibration and length vibration all of cylindrical-types. Thus, the washing optimal part and the depth of massage are prevented from being fixed. COPYRIGHT: (C)2005,JPO&NCIPI
