Effect of the of Zeolite Containing Silver-Zinc Nanoparticles on the Push out Bond Strength of Mineral Trioxide Aggregate in Simulated Furcation Perforation

摘要: Statement of the Problem Recently, zeolite has been regarded to improve properties dental materials such as mineral trioxide aggregate (MTA). Purpose The aim present study was evaluate effect incorporating zeolite/silver/zinc (Ze/Ag/Zn) composite at 2 wt% MTA powder on push-out bond strength in simulated furcation perforations. Materials and Method Furcal perforations, measuring 1.3 mm diameter height, were 40 human mandibular first molars. samples allocated two groups (n=20) based material used for repair In group 1, 2, plus Ze/Ag/Zn (2%) used. incubated 37°C 1 week. Then universal testing machine employed measure strength. resistance dislodgment recorded MPa. Data analyzed using t-test. Statistical significance set p< 0.05. Results (6.40±1.98 MPa) significantly higher than that (2.1±0.6 with p= 0.001. Conclusion Under limitations study, it can be concluded incorporation had a negative
