The aim of this study was to evaluate the effect of adding 10% calcium chloride ( CaCl 2 ) on the setting time, solubility and the p H of calcium‐enriched mixture ( CEM ) cement. Setting time was assessed in accordance with A merican D ental A ssociation specification N °57. Solubility was measured at 24 and 72 h, 7 and 14 days in hydrated and dehydrated conditions by calculating weight change. The p H of M ili Q water in which the CEM cement samples were immersed was measured immediately after each time interval with and without the addition of CaCl 2 . The data were analysed using the M ann– W hitney U ‐test and the S tudent's t ‐test. The initial setting time was significantly decreased after the addition of 10% CaCl 2 . The pH of water increased immediately when in contact with the cements in both groups. The weight loss of hydrated and dehydrated specimens was more than 3% and was significantly reduced by the addition of 10% CaCl 2 .
