Abstract:
Objective To investigate whether 5% strontium-containing brushite bone cements(DCPD) has repair effect on alveolar bone defects in osteoporotic rabbits. Methods Eighteen healthy adult female rabbits were used to establish osteoporosis models and were randomly divided into three groups:the blank control group, DCPD group,doped 5%DCPD group(5%strontium),with 6 rats in each group.In addition to the blank group, rats the other groups were filled with the corresponding bone cements in the bilateral alveolar bone defects. At 4 weeks and 8 weeks after operation,3 rats in each group were killed and given shooting the defect area X-ray.The expression of b-FGF was detected by immunohistochemistry. Results X-ray results showed that the defected of doped 5% DCPD group have been nearly completedat the 8 week,DCPD group partially completed repair,but blank group was not fully repaired. The results of immunohistochemistry showed that the expression of b-FGF was the highest at 4 weeks and decreased at 8 weeks after operation.Expression of b-FGF was significantly different at 4 weeks and 8 weeks among the three groups.Conclusion The 5%strontium-containing brushite bone cements can repair bone defect in osteoporotic rabbits.
