Abstract

The adhesiveness between the resin cements and pretreated dentin was studied. As the resin cement, Bistite resin cement (BI), Imperva dual cement (ID), Super-Bond D Liner plus (SB) were used. The polished dentin surface was pretreated with manufacture's instruction, 10T-2, 10T-2+photobond, NPG agent. 10T-2 was self-etching primer containing tannnic acid and FeCl3, and NPG agent was photocurable bonding agent containing MTYA, GM, glutaraldehyde, and QTX. After the pretreatment, each resin cement was applied on the pretreated dentin surface. The shear bond strengths were measured by universal testing machine after the immersion in 37°C water for 24hr.<BR>The bond strengths according to the manufacture's instruction were 6MPa for BI, 7MPa for ID, and 11MPa for SB. The pretreatment by 10T-2+photobond gave the high bond strength for BI, ID, and SB, but that by NPG agent gave high bond strength for BI.
