Abstract:
A hand-held ultrasonic tooth-cleaning apparatus which may be inserted into the mouth to remove materials from the teeth by cavitation using a lip seal or a continuous liquid flow. Electromechanical transducer elements are used to establish propagation of ultrasonic energy in a transverse mode with respect to the longitudinal axis of a vibrating member one terminus of which constitutes the probe which is inserted into the mouth by the user.
