Abstract :Aim: To evaluate the shear bond strength (SBS) of restorative materials applied to base materials and pulp capping agents using different techniques in-vitro. Materials and Method: A total of 80 acrylic blocks were obtained. Either Fuji II LC (FLC) or Biodentine (BD) was applied to the cavities opened in the center of the acrylic blocks. Thereafter, EverX Posterior (EXP) and Fuji IX (FIX) were used in a transparent plastic tube in accordance with the manufacturer’s instructions in one group and placed after pre-heating in another group (n=10). Then the SBS test was performed. Three-way ANOVA test was used to evaluate the effect of base material/pulp capping agent, restorative material and application technique on SBS. One-way ANOVA test was used for comparisons of individual parameters between groups in application techniques. Tamhane’s T2 test was used to determine the group causing the difference. Chi-square test, Fisher’s Exact test, Fisher Freeman Halton Exact Chi-square test and Yates continuity correction were used to compare qualitative data. Significance was evaluated at p<0.05 level. Results: After pre-heating, the SBS values of EXP to BD (6.4±3.0 MPa) was significantly greater than that of FIX (1.2±0.4 MPa) (p<0.05). When FLC material was used, the SBS values of EXP material were found to be higher than FIX material, regardless of the application technique. Conclusion: When a base material containing resin is used, it can be concluded that using a composite resin restorative material is more appropriate in terms of obtaining higher SBS values.
