Aim The aim of this study is to compare the shear bond strength of calcium silicate-containing biomaterials to Universal adhesive systems with different pH. Materials and Methods 63 acrylic blocks with cylindrical cavities (4 mm diameter - 2 mm depth) were prepared in square molds with a diameter of 20 millimeters (mm) and a depth of 20 mm. It was divided into nine groups. In accordance with the instructions of the manufacturers, 21 pieces of each biomaterial (NeoPutty, Theracal PT, Biodentine) were placed in the prepared cavities. Universal Adhesive systems on biomaterials After Gluma Bond Universal, Single Bond Universal, G-Premio Bond were applied according to the manufacturer's instructions, the composite resin was placed in cylindrical plastic tube with a diameter of 2 mm and a height of 2 mm prepared from polyethylene and polymerized with a LED light device for 20 seconds. Shear bond strength of all samples were measured in Newtons using a universal tester. According to the results of Shapiro-wilk test, One Way (One Way ANOVA) Analysis of Variance method, statistical parametric tests, was applied. The groups were compared among themselves with the Post hoc Tukey HSD test. Results The difference between Biodentin and TheraCal PT groups was statistically significant P<0.05. The difference between Theracal PT and NeoPutty groups was statistically significant P<0.05. The difference between Biodentin and NeoPutty groups was not statistically significant P>0.05. Conclusion In vital pulp treatments, it can be preferred to use with calcium silicate-based resin-containing TheraCal PT Universal adhesive systems. However, further histological studies are needed to evaluate its effects on vital pulp. Although the shear bond values of NeoPutty were lower than Biodentin, this result was not statistically significant. It was thought that in vivo studies are needed to understand the bonding mechanism of adhesive systems to NeoPutty in composite restorations.
