In image diagnosis in dentistry, the functional imaging for grasping details of caries is required. In this study, the samples were prepared by slicing "healthy" and "carious" teethes to a uniform thickness.The energy discrimination imaging and image processing were performed using a photon-counting X-ray imager. The image discrimination of enamel, dentin and carious parts was performed.
