Methodologies for measuring the setting times of mineral trioxide aggregate and Portland cement products used in dentistryDOI: 10.3109/23337931.2015.1135746 Keywords: Mineral trioxide aggregate, Portland cement, particle size, setting time, rheology Abstract: Objective The current standard used to measure setting time for Mineral Trioxide Aggregate (MTA) involves indentation testing with arbitrary weights. This study compared indentation testing against rheological measurements and assessed the influences of particle size and the inclusion of bismuth oxide on the setting time of experimental MTA and Portland cement (PC)
