Abstract
- The osteoporosis is a disease that represents a reduction in the volume of bony tissue relative to whole bone volume. And mandible also may be affected. Such porotic mandible may influence the result of the surgery like dental implant surgery relating mandible. So, the author examed the panoramic view of 89 persons for finding the possibility of useful diagnostic parameters of osteoporosis. To know the correlationship between the condition of vertebra and mandible, bone marrow density of lumbar spine from 2nd to 4th, and the number of residual tooth , panoramic mandibular index(PMI), angular cortical bone thickness(ACT) and ramus cortical bone thickness(RCT) were compared. The result is that PMI and ACT have similiar relative weak linear correlationship, RCT have very weak linear correlationship, the number of residual tooth have not linear correlationship.
