Abstract
The aim of this study was to compare the physical properties of the paste type MTAs with the powder-liquid mix type MTAs. The MTAs evaluated were 4 kinds of powder-liquid mix type and 2 kinds of paste type. Physical properties, such as, flow, film thickness, setting time, solubility, and radiopacity were evaluated in accordance with ISO 6876:2012. Experimental results were analysed using the Tukey multiple comparison test (p=0.05). Paste type MTAs showed higher flow and lower film thickness than powder-liquid mix type MTAs. The setting time of paste type MTAs was significantly shorter than for the powder-liquid mix type MTAs (p<0.05). Paste type MTAs showed similar solubility and radiopacity to powder-liquid mix type MTAs. Based on the results of this study, paste type MTA can be used as substitute for the conventional powder-liquid mix type MTA.
