Four different membranes were used in conjunction with porous calcium phosphate granules to treat grade II furcations in lower molars of 6 dogs. Six months later block sections were used to measure the amount of regeneration and inflammation. The 4 membranes (polycarbonate, silicone rubber, polytetrafluoroethylene, and polycaprolactone) all gave similar improvements in bone fill ranging from 1.74 ± 0.44 mm to 2.02 ± 0.38 mm while control areas had only 0.34 ± 0.12 mm. The amount of new attachment ranged from 2.32 ± 0.62 mm to 2.58 ± 0.62 mm for the membranes and was 0.26 ±0.11 mm for controls. There were increased numbers of chronic inflammatory cells seen with the polycarbonate and polycaprolactone group compared to controls and the other 2 membranes.J Periodontol 1993; 64:1154-1156.
