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) %K Mineral trioxide aggregate %K Portland cement %K particle size %K setting time %K rheology %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5433181/
