Bone Morphogenetic Protein-2 In Grade II Furcation Defects.

The collagen sponge is impregnated with rhBMP-2 at a concentration of 0.5 μg/ml/1cm3 and were stored at 4°C. This rhBMP-2 impregnated collagen sponge was then dispensed at grade II furcation site

For preparation of PRF, patient's venous blood is collected into 10ml glass tube or glass-coated plastic tube and centrifuged at 2700 rpm for 12min which leads to two different layers in the test tube, the upper platelet rich fibrin and the lower RBC portion. The formed PRF clot could then be removed from the glass tube and used in grade II furcation
