Abstract
A system for determining dental caries in a patient's tooth, the system including a dental tray including a curved channel configured to be placed on the patient's teeth on the patient's lower jaw or below the patient's teeth on the patient's upper jaw, the channel includes a length, two side walls and a middle wall connecting the two side walls, and a U-shaped excitation-detection transducer defined by two side portions and a middle portion connecting the two side portions, the transducer configured to be supported on and slidingly coupled with the channel with a shape of the transducer conforming to a cross-sectional periphery of the channel, the transducer selectively positioned over a portion of the channel over the patient's tooth, wherein the transducer is used to excite surface acoustic waves (SAWs) in the tooth and to receive SAWs in the patient's tooth.
