Analysis of Portland cement with added radiopacifying agents - Cristinne Andrade Melo - Bog

Radiopacity is a mandatory property for all dental materials. This characteristic allows the material to be distinguished from dental surfaces by radiography. Portland cement (PC) has similar physicochemical and biological properties to mineral trioxide aggregate (MTA), except for the radiopacifier particle. The radiopacity of MTA, PC and PC with the addition of radiopacifiers: iodoform, lead oxide, zirconium oxide, bismuth subnitrate, barium sulphate and bismuth oxide in proportions of 15%, 20% and 30% was analyzed.
