Regenerative Therapy of Periodontal Bone Defects

To compare clinically and radiographically the efficacy of demineralized freeze-dried bone allograft with and without decortication in the treatment of periodontal intrabony defects assessed by gain in clinical attachment, reduction of pocket depth and radiographic bone fill.To evaluate clinically and radiographically the regenerative potential of demineralized freeze-dried bone graft (DFDBA) material in periodontal intrabony defects.To evaluate clinically and radiographically the regenerative potential of demineralized freeze-dried bone graft (DFDBA) when used in combination with decortication in periodontal intrabony defects.
