This study estimated the relationship between metacarpal bone mineral content and jawbone density.<br>The subjects were 141 patients who desired implant treatment and had undergone a thorough pre-operative CT examination. In the maxilla, bone mineral density (BMD) was measured at the cancellous bone between the nasal cavity and the maxillary sinus. In the mandible, BMD was measured at the cancellous bone beneath the mental foramen. The CT numbers were corrected by the quantitative computer tomography (QCT) method. Furthermore, the cortical indices of the mandible, i.e. C-PMI (Central-Panoramic Mandibular Index), and MCW (Mandibular Cortical Width) were measured and calculated from panoramic radiographs. The bone mineral content of the total body was obtained by ΣGS/D and MCI through Microdensitometry.<br>The following results were obtained.<br>1) Between the maxillary BMD and ΣGS/D and between the mandibular BMD and ΣGS/D, there was a correlation in females but no correlation in males.<br>2) Between the maxillary BMD and MCI, there was a correlation in females but no correlation in males. However, in the mandibular BMD and MCI there was no correlation in females and males.<br>3) Between C-PMI and ΣGS/D there was a correlation in both females and males.<br>4) Between C-PMI and MCI there was a correlation in both females and males.<br>5) Between MCW and ΣGS/D there was a correlation in both females and males.<br>6) Between MCW and MCI there was a correlation in females, but no correlation in males.<br>From the above results, it was concluded that the maxillary BMD and the cortical index of the mandible reflected changes in the metacarpal bone mineral content, while mandibular BMD did not.
