| Background: Some of the efforts to improve the properties of Mineral Trioxide Aggregate (MTA) include incorporation
of some nanoparticles such as Titanium dioxide (TiO2). The aim of this study was to evaluate the effect of
TiO2 nanoparticles on the setting time, working time, push-out bond strength and compressive strength of MTA.
Material and Methods: The physical properties to be evaluated were determined using the ISO 6786:2001 and 9917
specifications. Fifteen samples of each material (MTA or MTA with 1% weight ratio of TiO2 Nanoparticles) were
prepared for any evaluated physical property. Data were analyzed using descriptive statistics and T-test. Statistical
significance was set at P<0.05.
Results: There was the significant effect of the material type (presence and absence of TiO2 nanoparticles) on the
push-out bond strength, compressive strength, working time and setting time, with significantly higher values
achieved in the group with TiO2 nanoparticles than the group without these particles (P=0.01 for the setting time
and compressive strength, P=0.03 for the working time and P=0.001 for the bond strength).
Conclusions: Based on the findings of this in vitro study, incorporation of the TiO2 nanoparticles with weight ratio
of 1% increased the setting time, working time, compressive strength and push out bond strength of MTA. |
