Objective.

The aim of this study was to evaluate the compressive strength and setting time of MTA and Portland cement (PC) associated with bismuth oxide (BO), zirconium oxide (ZO), calcium tungstate (CT), and strontium carbonate (SC).

Methods.

For the compressive strength test, specimens were evaluated in an EMIC DL 2000 apparatus at 0.5 mm/min speed.

For evaluation of setting time, each material was analyzed using Gilmore-type needles.

The statistical analysis was performed with ANOVA and the Tukey tests, at 5% significance.

Results.

After 24 hours, the highest values were found for PC and PC + ZO.

At 21 days, PC + BO showed the lowest compressive strength among all the groups.

The initial setting time was greater for PC.

The final setting time was greater for PC and PC + CT, and MTA had the lowest among the evaluated materials (P<0.05).

Conclusion.

The results showed that all radiopacifying agents tested may potentially be used in association with PC to replace BO.
