| Abstract | ||
| Background: The ultimate goal of periodontal therapy is the regeneration of tissues destroyed by periodontal disease Fibronectin belongs to a group of high molecular weight glycoproteins that exist on cell surfaces. It is known to play a role in cell-to-cell and cell-to-substrate adhesion, as well as an essential role in osseointegration due to its capacity to make osteoblasts attach to the extracellular matrix(ECM) components. Combination of Fibronectin and commercially available bone grafts may hold a promising potential of enhanced bone regeneration. Objective: Comparison of the effect of fibronectin, Bovine-Derived Xenograft (BDX)and their combination for socket preservation through histologic and histomorphometric analysis. Material and Method: Thirty six clinically healthy adult New Zealand white male rabbits, were used in this study. The animals were equally divided into three groups; I-control group (defect was left empty as control), II- bio group (bio- oss was applied on the socket ) and III-( Bio Fibro group) bone and fibronectin group( socket was filled with Bovine-Derived Xenograft Bio-Oss® with fibronectin). At 4 and eight weeks the animals were sacrificed. Bone regeneration among the three groups was evaluated through histologic and histomorphometric analysis. Results: The most significant value of area percent of newly formed bone was observed in the (bone and fibronectin) group, then the fibronectin group, with the least amount recorded in the control group. The difference was extremely statistically significant (p<0.0001). The socket is almost filled with newly formed bone trabeculae with organized fibrous tissue in the fibronectin and bone group ( Bio Fibro group ) at eight weeks. Conclusion: Fibronectin is a useful biomaterial for the enhancement of bone formation. Combination of fibronectin and bovine graft seems to lead significantly to favorable bone regeneration and could be efficaciously used in the socket preservation. | ||
