Purpose: Hydroxyapatite/tri-calcium phosphate (HA/TCP) mixture is an osteoconductive material used as a bone graft substitute, and demineralised bone matrix (DBM) is an osteoinductive material. A combination of DBM and HA/TCP mixture would probably create a composite with both osteoconductive and osteoinductive properties. The purpose of this study was to determine the effect of the combination of DBM and HA/TCP mixture Oil healing of rat radius segmental defects. Methods: Twenty-four adult mate Wistar rats were used. Bilateral radial defects were created in each animal. Radial defects were implanted with DBM, HA/TCP mixture and a combination of both substances. Control defects were left unfilled. Ten weeks after implantation, the animals were sacrificed, and the radii were evaluated by radiograhic and histopathological studies. Results: The use of DBM alone demonstrated improved healing on radiographic and histological Studies compared to other groups and the Control group. There were no differences between the other two groups and the control group. Conclusion: The DBM group showed the best healing response. Combined use of DBM and HA/TCP mixture did not improve bone healing, and the osteoinductive properties of DBM were inhibited by HA/TCP Mixture.
