Radiopacity of Portland Cement Associated With Different Radiopacifying Agents
Journal of Endodontics, 05/22/09

Duarte MAH et al. - Portland cement/bismuth oxide and Portland cement/lead oxide presented the highest radiopacity values and differed significantly from the other materials, whereas Portland cement/zinc oxide presented the lowest radiopacity values of all mixtures. All tested substances presented higher radiopacity than that of dentin and may potentially be added to the Portland cement as radiopacifying agents. However, the possible interference of the radiopacifiers with the setting chemistry, biocompatibility, and physical properties of the Portland cement should be further investigated before any clinical recommendation can be done.
