Background: Periodontal Regeneration of any tissue type is a complex biological process in itself, requiring a triad of cells, locally acting growth factors, systemic hormones, and the extracellular matrix components in which these interact. Aims: The aim of this study was to compare the effectiveness of autogenous dentin graft (ADG) and demineralized freeze-dried bone allograft (DFDBA) with chorion membrane in the treatment of Grade II and III Furcation defects in patients with moderate-to-severe chronic periodontitis. Subjects and Methods: A total of 20 Grade II and III furcation defects in patients with moderate-to-severe chronic periodontitis were randomly assigned to either Group I (ADG + chorion membrane) or Group II (DFDBA + chorion membrane) and evaluated clinically for Gingival Index (GI), probing pocket depth (PPD), clinical attachment level (CAL), vertical bone depth (VBD), and horizontal bone depth (HBD) and radiographically for furcation bony defect (FBD). Results: Intragroup comparisons of clinical parameters GI, PPD, and CAL have shown a statistically significant reduction at the end of 3 months and 6 months, but intergroup comparison was not statistically significant. At the end of 6 months, there was a significant reduction in VBD in Group I (2.65 ± 0.71 mm) compared with Group II (4.00 ± 1.26 mm) and HBD (1.84 ± 0.59 mm) compared with Group II (3.95 ± 1.74 mm), respectively. At the end of 3 months and 6 months, FBD depth was significantly reduced in Group I (1.21 ± 1.10 and 0.43 ± 0.22 mm2, respectively) compared with the Group II (3.04 ± 2.45 and 2.68 ± 2.50 mm2, respectively). Conclusions: The results of the present study indicate that the use of ADG and chorion membrane improved all the clinical parameters. Individuals treated with ADG and chorion membrane showed significant reduction for VBD, HBD, and FBD in the treatment of Grade II and III furcation defects than in the individuals treated with DFDBA and chorion membrane.
