Researchers at NASA's Langley Research Center have developed diagnostic mapping system for making and recording differential measurements of periodontal structures of a dental patient. The invention employs first and second ultrasonic sensors controlled by a dental hand-piece to make measurements of the cemento-enamel-junction (CEJ) of each tooth and the depth of the periodontal pocket or cavity of the tooth relative its CEJ. These measurements are visually displayed, recorded (or mapped), and c...
