Abstract :
The complex permittivity of a tooth has been measured over the frequency range from 0.04 to 40 GHz. These measurements revealed that caries is affected by millimeter waves. This phenomenon has been confirmed by simulation and experiment. Furthermore, it is concluded that millimeter waves may be used for dental medical diagnosis as well as dental medical treatment
