Özet

Aim: The aim of this study was to evaluate the shear bond strength of different bulk-fill resin composite materials to two different base materials and three different pulp-capping agents in-vitro. Materials And Methods: This study was supported by Gazi University Scientific Research Projects Coordination Unit with the project code “TGA-2021-7152”. In the study, 100 acrylic blocks were prepared for placing the specimens. Cylindrical cavities with a diameter of 4 mm and a depth of 2 mm were prepared in the middle of the acrylic blocks. Two different base materials and three different pulp-capping agents were placed in the cavities in accordance with the manufacturer’s instructions.  Each group of specimens was divided in two subgroups. The high-viscosity bulkfill resin composite was placed on the specimens in one group and the flowable bulk-fill resin composite on the specimens in the other group in accordance with the manufacturer’s instructions through the transparent plastic tube. Then, the shear bond strength values of the specimens were measured using a universal tester. Mann Whitney test and Kruskal Wallis test were used for statistical analysis of the data. Results: The highest shear bond strength values (19.35 MPa) were observed in the group in which flowable bulk-fill resin composite was applied on conventional glass ionomer cement (p<0.05). The lowest shear bond strength values (4.34 MPa) were observed in the group in which high-viscosity bulk-fill resin composite was applied on the calcium silicate-based pulp-capping agent (p<0.05). Conclusion: Within the limitations of this study; if a calcium silicate-based pulp-capping agent is to be used during the restoration of the teeth, it can be said that choosing a flowable bulk-fill resin composite instead of a high-viscosity bulk-fill resin composite as the final restoration material may be more advantageous due to better adhesion between the materials.
