This study aimed to compare the physical properties of 4 kinds of calcium silicatebased cements (CSCs): 2 kinds of powder-liquid mix type (RetroMTA¢ç [RTMX] and Endocem¢ç MTA Zr [EZMX]) and 2 kinds of premixed type (Well-Root¢âPT [WRPR] and Endocem¢ç MTA premixed [ECPR]) CSCs, respectively. Further, we assessed the setting times, solubility values, and compressive strengths of the cements. The shortest setting time was observed for EZMX (123.33 ¡¾ 5.77 seconds), followed by RTMX (146.67 ¡¾ 5.77 seconds), ECPR (260.00 ¡¾ 17.32 seconds), and WRPR (460.00 ¡¾ 17.32 seconds), respectively. The highest solubility was observed for WRPR (9.01 ¡¾ 0.55%), followed by RTMX (2.17 ¡¾ 0.07%), EZMX (0.55 ¡¾ 0.03%), and ECPR (0.17 ¡¾ 0.03%). Furthermore, the highest compressive strength was observed for ECPR (76.67 ¡¾ 25.67 Mpa), followed by WRPR (38.39 ¡¾ 7.25 Mpa), RTMX (35.07 ¡¾ 5.34 Mpa), and EZMX (4.07 ¡¾ 0.60 Mpa). In conclusion, the premixed type CSCs (WRPR and ECPR) exhibited longer setting times compared to the powder-liquid mix type CSCs (EZMX and RTMX).
The solubility test showed that ECPR had the lowest solubility while WRPR had the highest solubility, with a statistically significant difference between them (p < 0.0083).
Additionally, the compressive strength test showed that ECPR had the highest compressive strength, while EZMX had the lowest compressive strength, also with a statistically significant difference between them (p < 0.0083). ECPR is a promising material as it is premixed, eliminating the need for mixing time, and it has also demonstrated improved solubility and compressive strength, making it a potentially favorable option for clinical use.
