The aim of this study was to evaluate the shear bond strength of three typical restorative materials - glass ionomer cement (GIC), resin-modified glass ionomer (RMGIC), and composite resin (CR) - to different pulp capping materials, i.e., Theracal LC™, Biodentine™, and ProRoot™ white MTA (WMTA).
90 acrylic blocks with a center hole were prepared. The holes were completely filled with three pulp capping materials (Theracal LC™, Biodentine™, and WMTA) with 30 specimens per capping material. The samples were then randomly divided into 3 subgroups of 10 specimens each and were overlaid with GIC, RMGIC, or CR. A total 9 specimen groups were prepared. The shear bond strength was assessed using a universal testing machine. Kruskal-Wallis test and Mann-Whitney U test were performed to compare the shear bond strength among the subgroups (p < 0.05). After the shear bond strength test, the fractured surfaces were examined under a stereomicroscope at a magnification of 25×.
The highest and lowest shear bond strength values were recorded for Theracal LC™-CR and Theracal LC™-GIC, respectively and only Theracal LC™-CR showed clinically acceptable shear bond strength. With regard to the shear bond strength to the three pulp capping materials, CR was found to be superior to RMGIC and GIC. Biodentine™ showed a higher shear bond strength compared to Theracal LC™ and WMTA when used with GIC. Therefore, within the limitations of this study, composite resin which can be applied to all types of tricalcium silicate based pulp capping materials is recommended.
