Shear Bond Comparison Between Four Bioceramic Materials and Dual Cure Composite Resin

Abstract

Bioceramic materials have demonstrated biologic and physical properties favorable for regenerative treatment. A key contributor to treatment success is an adequate restoration to prevent microleakage; however, research is limited regarding the bond strength between bioceramic materials used in regenerative procedures and restorative materials. Objective: The purpose of this study was to compare the bond strength between four bioceramic materials and a dual cure composite resin. Methods: Eighty wells in Teflon blocks were divided evenly into 4 groups and filled with a bioceramic material: Group 1: White ProRoot MTA; Group 2: Biodentine; Group 3: EndoSequence RRM Fast Set Putty; Group 4: NeoMTA. After allowing the materials to set according to manufacturers instructions, the exposed surfaces of the bioceramic materials were prepared using ClearFil SE Bond followed by restoration with ClearFil DC Core Plus. To test shear bond strength, each block was secured in a universal testing machine and the crosshead was advanced at 0.5mm/min until fracture. Newton peak force was recorded and MPa calculated. Data was analyzed by Independent Kruskal-Wallis Test and Dunns Post Hoc Test (p<0.05). Results: Mean shear bond strengths between ClearFil DC Core Plus and the bioceramic material groups were: White ProRoot MTA 7.96 MPa; Biodentine 9.18 MPa; EndoSequence RRM Fast Set Putty 4.47 MPa; NeoMTA 5.72 MPa. White ProRoot MTA and Biodentine were statistically similar, with higher stress bond strength than NeoMTA which had a statistically greater bond strength than Endo Sequence Root Repair Material. However, these differences are clinically insignificant. Conclusion: The choice of which bioceramic material to use in regenerative procedures should be based on factors other than the bond between that material and the overlying coronal resin restoration.
