| Research Abstract |
Osteoporosis shows the decrease of bone quantity and quality. In this disease, collagen, a determinant of bone quality, declines quantitatively and qualitatively, so did even in the mandible. In the mandibles which did not have osteoporotic condition, collagen quantity and quality exhibited inter-individual variation but not dependence on bone quantity and aging. Bone quantity of the mandible exhibited variation among individuals, but did not depend on aging except for in the cortical bone in females. Collagen biochemical conditions in the mandible appear to be less related with the bone quantity, rather be closely related with the bone quality.
