Bonding of restorative materials to tooth structure has become one of the prime objectives of modern dentistry. Traditional glass ionomers have generally been relegated to a secondary role in favour of composite resins. To circumvent these problems of traditional GIC, resin modified GIC, and polyacid modified composite resins have been introduced having good adhesion and improved properties. Hence a study was undertaken to compare and evaluate shear bond strengths of Resin Modified GIC and Poly acid modified composite resin to enamel and dentin on 40 extracted teeth. Poly acid modified composite resin showed significantly higher bond strength values to both enamel and dentin. Also both the compomer and resin modified GIC show significantly high shear bond strength value to enamel than to dentin.
