T
he receptor activator of nuclear factor-kB ligand (RANKL) and osteoprotegerin (OPG) system are regarded as the fundamental
reason for systemic osteoporosis while alfacalcidol is a basicmedicine for osteoporosis. But it is uncertainwhether RANK/RANKL/
OPG is involved in the mandible osteoporosis and whether alfacalcidol could be used for the treatment of mandible osteoporosis. This
study is to investigate the expression of RANKL/RANKL/OPG in mandible and femur and to discuss the relationship between the
systematic osteoporosis and mandible osteoporosis, as well as the effects of alfacalcidon on aged male rats. We observed that as the
rats aged, the expression of RANKL increased obviously and the ratio of RANKL/OPG also increased, the absorption is obvious in
femur. In comparison, the ratio of RANKL/OPG was decreased in mandible and the absorption and formation in mandible was at a
relatively low level. Therefore, it was suggested that the mandible osteoporosis was not completely synchronous to femur. Alfacalcidol
was conductive to the bone mass and bone mineral density in femur and mandible.
