Aim and Objectives: The objective of the study was to clinically and radiographically compare and evaluate the regenerative potential of recombinant human bone morphogenetic protein-2 (RhBMP-2) impregnated with absorbable collagen sponge and platelet-rich fibrin (PRF) in the treatment of Grade II furcation defects. Patients and Methods: Thirty-two subjects were randomly assigned to each of the following groups: bone morphogenetic protein (BMP) group and PRF group, with one defect/subject. Sixteen Grade II furcation defects were treated with RhBMP-2 impregnated with absorbable collagen sponge in the BMP group and the remaining 16 defects were treated with PRF in the PRF group. Clinical and radiographic parameters which were evaluated at baseline, postoperative 1 week, 3 months, and 6 months were probing pocket depth, clinical attachment level, scoring of plaque index, and gingival index, and the bone fill was evaluated using Digital Subtraction technique and morphometric area analysis with ImageJ® software. Results: RhBMP-2 in absorbable collagen sponge was effective in increasing the bone fill in Grade II furcation defects when compared to PRF alone (P = 0.05). In relation to clinical parameters, both the groups showed no statistical significance between them. Conclusion: The unique regenerative potential of RhBMP-2 impregnated with absorbable collagen sponge makes it a potential agent to be used as a graft material for the treatment of Grade II furcation defects.
