Özet
Aim: To evaluate the microshear bond strength (mu SBS) of mineral trioxide aggregate and Biodentine to various resin-based materials using different adhesive strategies. Materials and Methods: Three resin-based materials-a self-adhering resin composite with or without acid etching (Vertise flow; Kerr, Orange, CA, USA), a conventional flowable composite with a total-etch adhesive (Filtek Ultimate Flowable; 3M ESPE, St. Paul, MN, USA), and a flowable resin-modified glass ionomer cement (RMGIC) without any surface modification (lonoseal; VOCO GmbH, Cuxhaven, Germany)-and two calcium-silicate-based materials-Biodentine and BIOfactor mineral trioxide aggregate (MTA)-were tested. A total of 100 cylindrical acrylic molds were prepared. Biodentine and BlOfactor MTA were prepared and placed into the central holes on the molds. Specimens were divided into two main groups according to materials and into five subgroups (n = 10). mu SBS were evaluated using a mu SBS testing device. The failure modes were examined under a stereomicroscope with magnification. They were categorized as adhesive, cohesive, or mixed. Data were analyzed using two-way analysis of variance (ANOVA) and Tukey test. The significance level was taken as alpha = 0.05. Results: It was observed that both calcium-silicate-based material type and resin-based material type influenced the mu SBS significantly according to two-way ANOVA. Biodentine exhibited higher bond strength values than MTA. However, no statistically significant interaction was demonstrated between these factors (P = .396). The mu SBS values of intermediate materials to Biodentine and MTA were listed from the lowest to the highest as follows: RMGIC < Acid Etch + RMGIC < SARC (self-adhering resin composite) < FC (flowable composite) < Acid Etch + SARC. Conclusion: Self-adhering composites can be used on calcium-silicate-based materials in vital pulp treatments because of their mechanical properties. Acid-etching ensures high mu SBS values. Although the mu SBS of Biodentine were higher than MTA according to this study's results, there was no statistically significant difference in mu SBS of FC and acid-etched SARC to MTA.
