 note = {P(論文), In measuring the dentin mineral density (DMD), X-ray absorptiometry using slices of tooth after tooth extraction (the Slice method) is used conventionally. Because it takes time and must extract a tooth, these methods are limited to usable cases. Therefore we investigated a method to measure DMD by CT scan (the CT method). Cervical dentin in the alveolar bone was measured to avoid the influence by the beam hardening effect. The area where DMD value showed a plateau was measured to avoid the influence of the partial volume effect. DMD by CT method accorded with Slice method with a difference of 1.2%. Using this CT method, a difference of DMD among kind of tooth in the same individual was measured in 16 cases without metal restoration or prosthetic appliance in Ohu University Hospital. There were a few differences in DMD and the standard deviation of a measured value was about around 1.5%. Thus, it is suggested that all kind of tooth are usefl as diagnostic standard and the CT value of dentine is effective if measured using the CT method.},
