عنوان انگلیسی Effect of Different Water-to-Powder Ratios on the Compressive Strength of Calcium-enriched Mixture Cement
چکیده انگلیسی مقاله Introduction: Calcium-enriched Mixture (CEM) cement is an endodontic reparative material available in the form of powder and liquid. The purpose of this in vitro study was to determine the effect of different water-to-powder (WP) proportions on the compressive strength (CS) of the cement. Method Materials and: One gram of CEM cement powder was mixed with either 0.33 g, 0.4 g or 0.5 g CEM liquid. The mixture was transferred to metallic cylindrical molds ( n =10) with internal dimensions of 6±0.1 mm height and 4 ±0.1 mm diameter. After 4 days, the specimens were subjected to compressive strength tests using a universal testing machine. The data were analyzed by One-way ANOVA and Tukey’s tests at a significance level of 0.05. Results: Statically significant difference was found among experimental groups ( P < 0.05). The 0.33 WP ratio showed significantly greater CS value compared to 0.4 and 0.5 proportions ( P =0.012 and P =0.000, respectively). The CS of 0.4 WP ratio was also significantly higher than that of 0.5 WP ratio ( P =0.014). Conclusion: According to the results, higher WP ratios results in lower CS of the cement.
