| Research Abstract |
Clinical diagnosis of initial regions of dental caries is important for oral health promotion and prevention of dental caries. To development of diagnostic devices of tooth surfaces condition, including the initial caries regions, we utilized the ultrasonic mineralization measurement system of hard tissues with ultrasonic technology of haptic sensor. In the clinical use of the ultrasonic mineralization measurement system, the thermal protective equipment was needed for the stabilization of readout, which was sensitively influent to the thermal shift of the sensing oscillator. Furthermore, for the data management of mass oral health check-up, the dental chart input method system was developed. Thus, the evaluation system of caries risk assessment was established.
