Abstract

Aim

To evaluate the effect of adding white Portland cement, in the ratio of 25% by weight, on the physical properties of MTA Fillapex.

Methodology

White Portland cement (WPC) powder was incorporated into the paste of mixed MTA Fillapex in the ratio of 25% by weight. Different properties including powder-paste ratio, strength properties, setting time, film thickness, water solubility, and push out bond strength were studied in comparison to MTA Fillapex.

Results

The experimental material showed higher setting time, higher film thickness, higher solubility, higher diametral tensile strength, and higher compressive strength, though the last one was not statistically significant. On the other hand, the push out bond strength of the experimental material was significantly lower.

Conclusions

Addition of Portland cement to MTA Fillapex increases its setting time, film thickness, solubility, diametral tensile strength and compressive strength. However, its push-out bond strength decreased.
