    摘要： A power toothbrush (10) is disclosed having a handle (15), battery (12), ultrasonic drive circuit (14), motor (16), control unit (18), and toothbrush head (20). The toothbrush head includes bristles (26) and a waveguide (24) that is operatively connected to an ultrasonic transducer (22). The waveguide facilitates the transmission of acoustic energy into the dental fluid to achieve improved cleaning and stain removal and improved cleaning in interproximal and subgingival regions. In one embodiment an ultrasound transducer module (30) includes a plurality of piezoelectric elements (32, 34) that may be mechanically connected in series, and electrically connected in parallel. One or more contacts (36) connect the elements, and a waveguide structure (50). An impedance matching layer (38) may be provided between the waveguide and the ultrasonic transducer module. The waveguide may be formed from a relatively soft material, for example, a polymer having a hardness between 10 and 65 Shore A.

    摘要： Oral hygiene devices employing an ultrasound transducer are disclosed. The device is user-activatable to commence an operating cycle, and has a controller that may provide a timing function and may provide a variable level of ultrasound transducer output during an operating cycle. The controller may provide a monitoring function that is capable of detecting an ultrasound transducer fault condition and alert a user, through a user interface, when an ultrasound transducer fault condition is detected. The controller may be programmed to count the number of device operating cycles or accumulate the total device operating time and activate a transducer replacement signal following a predetermined number of uses or a predetermined accumulated operating time. The ultrasound transducer assembly may be provided in operative communication with an ultrasound drive circuit and power supply by means of a transformer assembly that inductively couples and transfers power from the ultrasound drive circuit to the ultrasound transducer.
