The present in vitro study aimed to evaluate the influence of various surface treatments on the micro-shear bond strength (& mu;SBS) of calcium silicate-based materials (CSMs) to resin composite. Two hundred and forty cylindrical acrylic molds were filled with Biodentine, NeoMTA Plus, NeoPUTTY MTA, TheraCal LC, and Well-Root PT. The specimens were divided into four groups: control with no surface treatment, acid-etching, tribochemical silica coating (TSC), sandblasting with aluminum oxide (AL). Resin composite was applied and photo-polymerized. The & mu;SBS was measured and surface alterations were evaluated using a SEM. Data were examined using two-way ANOVA and Tukey tests at a significance level of 5%. The lowest bond strength values were detected in the controls. Moreover, the lowest & mu;SBS was demonstrated in the untreated NeoMTA Plus group, whereas the aluminum oxide-treated TheraCal LC group exhibited the highest bond strength (p < 0.05). Cohesive failures were observed dominantly for Biodentine and TheraCal LC, adhesive failures in Well-Root PT, and mixed failures for NeoPUTTY MTA. Surface treatments increased the & mu;SBS values of CSMs and affected the micromorphology of the sample surfaces. The study suggests that surface treatments would be advantageous on CSMs.
