Purpose: This in-vitro study aimed to evaluate the shear bond strength of different resin composites to Biodentine. Materials & Methods: Sixty acrylic blocks with a central hole (2mmx5mm) were fabricated(n=60). The holes were filled with Biodentine(Septodont), and the samples were randomly divided into three groups based on the type of restorative material: 1)Conventional posterior composite, Estelite Posterior Quick (EP)(Tokuyama); 2) Bulk-fill composite, Filtek Bulk Fill (FB)(3M ESPE); and 3) Short fiber-reinforced composite, EverX Posterior (EX)(GC). Additionally, each group was subdivided into two categories depending on the adhesive application method: self-etch and total-etch. A universal adhesive(Single Bond Universal,3M ESPE) was applied to the Biodentine specimens. Subsequently, the resin composites were applied and light-cured for 20 seconds. The shear bond strength was measured using a universal testing machine (AGS-1000D, Shimadzu) at a crosshead speed of 1 mm/min. The shear bond strength data (MPa) were analyzed using two-way ANOVA and the Bonferroni test(p
