Background and Objective: Hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP) grafts have shown to be effective in promoting the clinical signs of periodontal regeneration in intrabony defects. The aim of our study was to clinically and radiographically evaluate the efficacy of HA and β-TCP composite bone graft material in the treatment of intrabony three-wall defect. Materials and Methods: Twenty patients participated in this study. Interproximal bony defects were surgically treated with a combination of HA-βTCP (biphasic calcium phosphate). Changes in clinical parameters such as gingival status, probing pocket depth, clinical attachment, and radiographic estimation of the amount of bone fill were evaluated after 6 months postoperatively. Statistical Analysis Used : Student's " t" test. Results: This treatment modality resulted in significant pocket depth reduction and clinical attachment gain which were observed to be 2.938 mm (47.04%) and 3.188 mm (29.09%), respectively. The defect fill as seen radiographically was 3.204 mm (63.195%). All the differences were highly significant and in favor of postoperative group. Conclusion: The results of this study suggest that HA-βTCP (biphasic calcium phosphate) provides an added regenerative effect in promoting the clinical resolution of intrabony three-wall defects in patients with periodontitis.
