Toward applying terahertz waves to caries diagnosis, THz-TDS measurements were performed on bovine tooth enamel, dentin, and decalcified dentin. In this study, we performed measurements extending beyond 2 THz. As a result, in the terahertz region, the Absorption coefficient of each component was significantly different on the high-frequency side. This result shows the potential of terahertz waves for application in caries diagnosis.
