This study aimed to evaluate and compare the effect of 1% phytic acid as a mixing medium on the setting times and diametral tensile strengths of different calcium silicate‐based cements. Specimens for four experimental groups ( n = 20/each) were fabricated by mixing ProRoot MTA ® (Dentsply) and Biodentine ® (Septodont) powders with their original liquids or with 1% phytic acid. Half of the samples in each group were immediately subjected to setting time tests, whereas the remaining half was subjected to the diametral tensile strength test after 3 weeks. When mixed with their original liquids, the setting time of MTA was significantly longer than that of Biodentine ® ( P < 0.05). When mixed with phytic acid, the initial and final setting times of both test materials significantly decreased ( P < 0.05). The diametral tensile strength of Biodentine ® was significantly greater than that of MTA ( P < 0.05). However, phytic acid had no effect on this outcome ( P > 0.05).
