Diagnosis of dental caries using millimeter wave reflection

Diagnosis of dental caries using millimeter wave reflection

It has been revealed that dental caries are significantly lossy than sound tooth in millimeter waves. In order to diagnose dental caries noninvasively, reflection coefficient of the dental caries is measured and compared to that of sound tooth. The simulation is performed to obtain electromagnetic (...

Zusammenfassung:It has been revealed that dental caries are significantly lossy than sound tooth in millimeter waves. In order to diagnose dental caries noninvasively, reflection coefficient of the dental caries is measured and compared to that of sound tooth. The simulation is performed to obtain electromagnetic (EM) wave distribution. The reflection change in frequency domain shows that the caries can be detected by millimeter waves.
