| dc.description.abstract | The aim of the present study was to establish the influence of different materials on the process of bone regeneration in post extraction sockets of ovariectomized (OVX) adult female rats. For this, 40 Sprague Dawley rats were used, divided into an experimental group (OVX) (n=20) and a control group (without ovariectomy) (n=20). All rats in the experimental group underwent bilateral ovariectomy to simulate a state of estrogen deficiency osteoporosis. After 12 weeks post OVX, rats from both groups were divided into 4 subgroups, in which the upper right first molar of each rat was extracted. Subsequently, the therapies performed in the post extraction sockets were A: (N=5) Unfilled alveolus to be used as a negative control. B: (N=5) Biphasic graft application (HA+BTCP). C: (N=5) PRF application. D: Application of a combination of biphasic graft + PRF. After three weeks, the animals were euthanized, and the samples were obtained for the respective analyses. All animals survived to the end of the study without any postoperative complications. The quantitative results of the interradicular bone area of ??the upper second molar showed significant differences between the control group and the OVX group. While no differences were observed in the histological description or in the quantitative analysis of collagen fibers type I and III. It is possible to conclude that the model of osteoporosis induced by estrogen deficiency would modify the bone microarchitecture of the Maxilla. However, new studies are necessary to continue with the study of biomaterials for bone regeneration in models of induced osteoporosis. | |
