ABSTRACT
The primary goal of periodontal therapy is to restore the tooth supporting tissues lost due to periodontal disease. The aim of the present study was to evaluate the efficacy of xenogenic bone graft with open flap debridement (OFD) in treatment of periodontal intrabony defects. Methods: Twenty intrabony defects were surgically treated. The defects were randomly assigned to treatment with OFD + bone graft (Group B) or OFD alone (Group A). The clinical efficacy of two treatment modalities was evaluated at 9months postoperatively clinically and radiographically. Results: Statistically significant intra group improvements were seen with all the hard tissue and soft tissue parameters in both test and control groups. Statistically significant improvements were seen in group B with clinical parameters and the mean defect fill (AC-BOD) when intergroup comparisons were made. Conclusion: Treatment with bone graft + OFD led to a significantly more favorable clinical outcome in intrabony defects as compared to OFD alone.
