Materiais radiopacificadores para cimentos endodônticos à base de cimento portland: uma revisão de literatura

Abstract

When filling the root canal system, the gap left by the inflamed pulp that is removed must be filled with a thin layer of cement. The Mineral Trioxide Aggregate is the most used and commercialized endodontic cement because it has biocompatibility properties and the ability to promote a regenerative reaction of human biological tissue. However, it has some disadvantages, the main ones being the high cost and tooth discoloration due to the presence of bismuth oxide in its composition. Therefore, other alternative materials to the use of bismuth have been studied. This study aimed to review the literature on recent discoveries in relation to radiopacifying agents used in endodontic cements. It was concluded that cements composed of alternative radiopacifying agents, such as calcium tungstate, niobium oxide and zirconium oxide, promote less chromatic alteration.
