Description

In this study, 4-META-containing (MC) and HEMA-containing (HC) adhesives were prepared. The effect of the amount of water added to the MC or HC adhesive on the demineralized amount of tooth apatite and tooth bonding performance were examined. The efficacy of 4-META was compared with that of HEMA. Increases in the amount of water resulted in increases in the demineralized amount of enamel and dentin apatite. However, the bond strengths of both adhesives were independent of the demineralized amount of tooth apatite. The MC adhesive exhibited a higher dentin bond strength than the HC adhesive. These results suggest that the addition of 4-META to one-step adhesive enhances the dentin bond strength more effectively than that of HEMA.
