Cimentos biocerâmicos como materiais seladores em perfurações radiculares: uma revisão de literatura

Abstract

Root perforations are communications between the supporting tissues and the root canal, i.e., the contact between the root canal, periodontium and alveolar bone. Their etiology may be due to iatrogenic or pathological factors. The objective of this work is to compare the advantages, disadvantages, physical and chemical properties of MTA which is the gold standard material in the sealing of root perforations with other materials such as Bio-C repair, Endosequence and Biodentine. This research is a descriptive review of the literature with a qualitative approach, performed through the electronic search of journals in the PubMed database. MTA was the first bioceramic material used in endodontic perforations, with excellent biocompatibility with adjacent tissues and sealing between tooth and supporting tissues. Biodentine has properties that overcome some limitations of MTA, so it is indicated when it is not possible to use the latter in root perforations. The main characteristic of Endosequence is that it can achieve its hardening even in contact with fluids or blood. Bio-C cement repair has been recently introduced in the Brazilian market and its components are similar to Endosequence cement. Among these materials studied, the Biodentine has demonstrated characteristics similar to MTA cement, overcoming its disadvantages, so this cement can be an effective alternative.
