摘要：This invention is a device and method for the detection of smooth surfacelesions such as caries and tooth crown surface cracks on a tooth crown surface, the devicehaving an ultrasonic surface wave transmitter/receiver (20) capable of transmittingultrasonic surface waves along a tooth crown surface. Surface lesions encountered by theultrasonic surface waves produce ultrasonic surface wave reflections which are receivableat the generator/receiver, thus enabling the presence of the lesion to be detected. Theultrasonic surface wave generator/receiver may comprise a transducer operativelyconnected to a wedge-like coupler (30). Longitudinal ultrasonic waves generated by thetransducer are imparted onto the tooth surface by the coupler which has a contactsurface in contact with the tooth surface being tested. The coupler also enablesultrasonic surface wave reflections to be received by the transducer.
