Objective The objective of this study was to evaluate the radiopacity of white Portland cement (PC) associated with bismuth oxide (Bi 2O 3), barium sulfate (BaSO 4), iodoform (CHI 3), and zirconium oxide (ZrO 2). White mineral trioxide aggregate (WMTA) and PC without radiopacifier were used as positive and negative controls, respectively.
