The goal of this study was to evaluate the effectiveness of demineralized bone matrix (DBM) putty, consisting of demineralized human bone allograft matrix in a carrier of bovine collagen and alginate, for the treatment of periodontal defects in humans. Twenty subjects with at least one site having a probing depth ≥ 6 mm and radiographic evidence of bony defect depth > 3 mm were included. The infrabony defects were grafted with DBM putty bone graft. The following clinical parameters were assessed at baseline and 6 months posttreatment: probing depth (PD), gingival recession (GR), and clinical attachment level (CAL). Bone fill was evaluated using transgingival probing and standardized radiographs taken at baseline and 6 months posttreatment. The 6-month evaluation showed a significant PD reduction of 3.27 1.67 mm and clinical attachment gain of 2.27 1.74 mm. Bone sounding measurements showed a mean clinical bone defect fill of 2.93 1.87 mm and a mean radiographic bone fill of 2.55 2.31 mm. The use of DBM putty was effective for treatment of periodontal bony defects in humans. Significant improvement in CAL, PD, and bone fill was observed at 6 months compared to baseline.
