The samples were allocated to two groups (n=20) based on the material used for the repair of perforations. In the group 1, MTA and in the group 2, MTA plus Ze/Ag/Zn (2%) was used. The samples were incubated at 37°C for 1 week. Then the universal testing machine was employed to measure bond strength. The resistance of materials to dislodgment was recorded in MPa. Data were analyzed using t-test. Statistical significance was set at p < 0.05.Results: The push-out bond strength in the group 1 (6.40±1.98 MPa) was significantly higher than that in the group 2 (2.1±0.6 MPa) with p= 0.001.Conclusion: Under the limitations of the present study, it can be concluded that incorporation of Ze/Ag/Zn at 2 wt% to MTA powder had a negative effect on the push-out bond strength. Key Words   ● Bond strength  ● MTA ● Nanoparticles  ● Push out  ● Zeolite UR - https://dentjods.sums.ac.ir/article_44919.html L1 - https://dentjods.sums.ac.ir/article_44919_f710c589085393c2af273a7c11e9e9b6.pdf ER -
