摘要

The present invention is directed to a method and apparatus for the detection of dental caries. The method comprises the steps of placing at least one probe electrode in electrical contact with a surface of a patient's tooth, placing a second electrode in electrical contact with another part of the body of the patient, passing an alternating electrical current between said probe and second electrodes, and measuring the electrical impedance between the electrodes.
