Introduction: The goal of this research was to examine the push out bond strength of four bioceramic materials to root dentin during regenerative endodontics. The bioceramics being tested were as follows: 1. Biodentine (Septodont), 2. EndoSequence BC Putty Fast Set (Brasseler), 3. NeoMTA Plus (Avalon Biomed), and 4. ProRoot MTA White (Dentsply).
Methods: 100 2.0 mm thick dentin slices with 0.3 mm and a 1.5 mm diameter. Group A: Biodentine (20); Group B: EndoSequence BC Putty Fast Set (20); Group C: NeoPutty (20); Group D: ProRoot MTA White (20); Group E: Portland cement (10); and Group F: Cavit (10). The values of push out bond strength were determined using a universal testing machine. The failure pattern was classified as either adhesive, cohesive, or mixed.
Results: The mean push out bond strength ± standard deviation in MPa values of Biodentine, Endosequence BC Putty Fast Set, NeoPutty, ProRoot MTA, Cavit, and Portland Cement were 8.63 ± 3.73, 16.03 ± 4.05, 7.29 ± 2.27, 10.69 ± 3.00, 1.07 ± 0.53, and 10.71 ± 3.47 respectively. Inspection of the samples revealed the bond failure of the bioceramics to be predominantly cohesive failure followed by mixed.
Conclusion: In clinical practice, there is a significant role played by the bond strength of the material. According to the results of the current research, the push out bond strength of EndoSequence BC Putty Fast Set was statistically superior to that of Biodentine, NeoPutty, ProRoot MTA, Cavit, and Portland Cement. The majority of bioceramic showed cohesive bond failure followed by mixed.
