Bond strength of bonding agents containing 2-methacryloyloxyethyl hydrogen maleate to dentin treated with K-etchant gel (KE), CA agent (CA), Scotchprep (SP) and ALL-BOND dentin conditioner (DC) was measured, and dentin surfaces, split dentin surfaces and resin-dentin interfaces were observed by SEM to investigate the correlation between the bonding of bonding agent and morphology of treated dentin surfaces. The bond strength to treated dentin ranged from 5.39 to 12.97 MPa. When pretreatment was with SP, the bond strength was highest. The morphology of dentin surfaces treated with KE and CA was similar and acidwidened dentin tubules and deposit at intertubular dentin were visible. For SP, intertubular dentin surface was flat and dentin tubules were widened. For DC, dentin tubules were not widened and dentin surface was rough. The treatment with KE resulted in the development of a porous layer the thickness of which was approximately 3μm. The deposit with about 1μm on the porous layer was visible. For CA, about 2μm deposit on dentin was visible. For SP and DC, the thin layer of deposite on dentin was visible. The bonding agent created acid-proof dentin layers with different thickness on the treated dentin surfaces. The layer thicknesses were about 3μm for KE, about 2μm for CA, about 1μm for SP and less than 1μm for DC.
