“…An endodontic biomaterial should exhibit ideal physical properties for successful clinical application (12). To achieve these ideal properties in hydraulic cements like MTA and PC, the particles should be thoroughly mixed with liquid.…”

“…The compressive strength shows the progression of hydration process and is an indicator of the setting reaction of the material (12,19,20). The compressive strength is not considered important in cases in which a material is used as a retrofilling material; however, in cases of furcal perforation repair and apexification it is an important property because in such cases the material is affected by occlusal forces, and forces resulting from the placement of material are exerted on the material (11,14).…”

“…The compressive strength is not considered important in cases in which a material is used as a retrofilling material; however, in cases of furcal perforation repair and apexification it is an important property because in such cases the material is affected by occlusal forces, and forces resulting from the placement of material are exerted on the material (11,14). This physical property depends on the liquid used for mixing, the pressure applied during placement of the material and the storage conditions of the material (12). In the present study, all the factors that affected the compressive strength were similar except for the mixing technique; and according to the findings, the strength of PC was not affected by the mixing technique, which is similar to the case with MTA (14).…”

BackgroundThe Portland cement is hydrophilic cement; as a result, the powder-to-liquid ratio affects the properties of the final mix. In addition, the mixing technique affects hydration. The aim of this study was to evaluate the effect of different mixing techniques (conventional, amalgamator and ultrasonic) on some selective physical properties of Portland cement.Material and MethodsThe physical properties to be evaluated were determined using the ISO 6786:2001 specification. One hundred sixty two samples of Portland cement were prepared for three mixing techniques for each physical property (each 6 samples). Data were analyzed using descriptive statistics, one-way ANOVA and post hoc Tukey tests. Statistical significance was set at P<0.05.ResultsThe mixing technique had no significant effect on the compressive strength, film thickness and flow of Portland cement (P>0.05). Dimensional changes (shrinkage), solubility and pH increased significantly by amalgamator and ultrasonic mixing techniques (P<0.05). The ultrasonic technique significantly decreased working time, and the amalgamator and ultrasonic techniques significantly decreased the setting time (P<0.05).ConclusionsThe mixing technique exerted no significant effect on the flow, film thickness and compressive strength of Portland cement samples. Key words:Physical properties, Portland cement, mixing methods.
