Özet

Purpose: The immediate and long-term microtensile bond strengths of two current universal adhesives used in self-etch (SE) or etch and rinse (ER) mode to caries-affected dentin compared to sound dentin were investigated. Material and methods: Dentin groups were identified using the Vickers microhardness test: control group (SD), caries-affected hard dentin (D1) and caries-affected semi-hard dentin (D2). Dentin-adhesive interfaces were examined by electron microscopy (SEM). Statistical analyses were performed using two-way ANOVA, Scheffé and independent t-test (p < 0.05). Results: It was shown that the bond strength of all adhesive systems to D2 was significantly lower than to SD (p < 0.05) and that D1 exhibited bond strength similar to SD, especially for adhesives applied in SE modes. Conclusions: According to the results of the study, dentin hardness, adhesive type and the application mode have an effect on the long-term bond strength to dentin.
