Furcation perforations were created in pulpal floor of 60 recently extracted molars and repaired with light cure glass ionomer, light cure composite resin, and silver amalgam with or without Gelfoam barrier. Teeth were immersed in 2% methelerie blue for 2 weeks and sectioned longitudinally and dye penetration was measured by a sterio microscope. The light cure glass ionomer showed minimum dye penetration (24%) followed by silver amalgam (34%) in barrier group. In non barrier group, both Glass ionomer and composite resin revealed 100% leakage while in silver amalgam, dye penetration was only 56%.
