Özet:

 Purpose: The aim of this study was to evaluate the bond strength between Biodentine, modified with polymethyl methacrylateMontmorillonite nanoclay, and resin composite at different stages of Biodentines setting time. Materials and Methods: Nanoclay was prepared and organo-modified with polymethyl methacrylate. The characterization of polymethyl methacrylateMontmorillonite nanoclay, Biodentine, and modified Biodentine was assessed by X-ray diffraction analysis, Fourier-transform infrared spectroscopy, and scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy. A total of sixty acrylic molds were constructed; thirty specimens were filled with Biodentine, and the other thirty with nanoclay-modified Biodentine. Each group was subdivided according to different stages of Biodentines setting time: 12 minutes, 2 hours, and 2 weeks. Universal adhesive, followed by flowable resin composite, was applied. The micro shear bond strength was tested using a universal testing machine. Data were analyzed using one-way ANOVA followed by Tukeys post hoc test, in addition to two-way ANOVA. The significance level was set at p  0.05. Results: The characterization results revealed the successful preparation of polymethyl methacrylateMontmorillonite nanoclay and modified Biodentine. The micro-shear bond strength results showed that modified Biodentine had significantly higher micro-shear bond strength than unmodified Biodentine at 12 minutes. However, no statistically significant difference was found between the unmodified and modified Biodentine groups at 2 hours and 2 weeks. Conclusion: The incorporation of 10 modified nanoclay by weight into Biodentine could enhance the bond strength with resin composite when placed after 12 minutes of Biodentines setting time.
