Abstract
Background: To evaluate the effect of hydrofluoric acid (HF), self-etching primer (Monobond Etch & Prime; MEP), and combined application of these protocols (HFMEP) on microtensile bond strength (µTBS) between polymer-infiltrated ceramic network material and resin cement. Methods: Specimens were divided into four groups based on the surface treatment applied: Control (C), HF, MEP, and HFMEP. Resin-ceramic beams were randomly divided into 2 subgroups according to aging condition: 1) 24 h water storage and 2) 10.000 thermocycling (TC). μTBS was measured using a universal testing device. The surface roughness (Ra) of additional samples (n=20) for each treatment group was measured using a profilometer. One sample per group was subjected to scanning electron microscopy. Data were analyzed by one- and two-way ANOVA, Tukey's HSD, and independent t-tests (α=.05). Results: C and HF groups exhibited the lowest and highest Ra values, respectively (p .05), but MEP treatment resulted in significantly higher μTBS values than in the HF-etched group after TC (p<.001). μTBS values for the HFMEP group were higher than those for solely HF or MEP-applied groups at baseline (p<.001). After TC, the μTBS values for all groups were reduced (p<.001). Conclusion: The combined application of hydrofluoric acid and self-etching primer effectively improved resin bond strength compared to hydrofluoric acid etching alone. The high μTBS values obtained after thermocycling with the self-etching primer application alone indicated that this application may be a viable treatment alternative for polymer-infiltrated ceramic network material.
