Cytotoxicity and Antibacterial Activity of Mineral Trioxide Aggregate Cement with Radiopacity Introduced by ZrO₂

Table 5

Impact of the sintered powder granulation on the final setting time, compressive strength, and kneading capacity of the cements kneaded with the following proportions: 3.6 g of the sinter/1.0 ml of the 15% CaCl₂ solution.

Symbol of the sintered powder	Final setting time (min)	Compressive strength (MPa)	Remarks on kneading
A	38	121.5 ± 9.9
B	27	136.8 ± 9.3
C	30	137.4 ± 9.4

– very easy to knead.
