Abstract

This study evaluated the effect of adding silane coupling agent on initial and long-term bond strengths of one-step self-etch adhesives to enamel-dentin-composite in combined situation. Cervical cavities were prepared on extracted molars and filled with Clearfil AP-X. After water-storage for one-week, the filled teeth were sectioned in halves to expose enamel, dentin and composite surfaces and then enamel-dentin-composite surface was totally applied with one of adhesive treatments (Clearfil SE One, Clearfil SE One with Clearfil Porcelain Bond Activator, Beautibond Multi, Beautibond Multi with Beautibond Multi PR Plus and Scotchbond Universal). After designed period, micro-shear bond strengths (μSBSs) to each substrate were determined. For each period of water-storage, additive silane treatments significantly increased μSBS to composite (p<0.001). On the other hand, they significantly decreased μSBS to dentin (p<0.001), although did not have adverse effect on μSBS to enamel (p>0.05). Moreover, the stability of μSBS was depended on materials and substrates used.
