Evaluation and Selection of Dental Materials Using the Magnetic Inspired Resonance Spectrum (MIRS)

The new concept “Hado” has been proposed, and the Hado analyzer has been developed as a device that can measure the degree of healthiness and the degree of disease progression as well as qualities of dental materials. However, these measurements are greatly affected by operator-related factors, including operator’s technical skill and emotional condition at the time of analysis. Moreover, interpretation of assessment results also varies among investigators. In the present study, 11 kinds of dental materials, placed in contact with the teeth during actual use, were measured by operators with different skills, using the magnetic inspired resonance spectrum (MIRS), and differences in measurements obtained were evaluated. Measurements were also made for subjects by experienced MIRS operators, and the results were evaluated and compared, in order to determine whether compatibility between the subject and each material could be evaluated, rather than comparison among dental materials.
