Aim: Evaluate the Bond strength and the Adaptation of Nano Biodentine as a repair material for furcation perforation.
Materials and methods: Thirty Samples were randomly classified into three groups (n=10), 1 control group (MTA) and 2 experimental groups according to the materials used to fill the furcal perforations defects. Group 1 (Biodentine), group 2 (Nano-Biodentine) and group (MTA).
Results: There was a significant difference between different groups (p < 0.001). The highest value was found in the MTA group (11.12±0.77) followed by the Nano-biodentine (7.31±1.19) while the lowest value was found in Biodentine (6.24±0.66). Post hoc pairwise comparisons were all statistically significant (p < 0.001).
Conclusion: Nano-biodentine showed to have the highest push-out bond strength, followed by the biodentine and then the MTA had the least pushout bond strength. While when looking at the adaptation of the materials, Nano-biodentine has the highest adaptation followed by Biodentine and the lastly came the MTA with the lowest adaptation.
