Abstract(s)
O sucesso do tratamento endodôntico está dependente de uma limpeza e conformação e posterior obturação dos canais radiculares, com o objetivo de obter um selamento hermético ideal, a fim de evitar o fracasso endodôntico. Para isso, é necessário obter a conjugação de materiais sólidos e plásticos, de modo, a que a sua combinação seja o mais biocompatível com os tecidos biológicos.
Este estudo apresenta uma revisão narrativa abrangente da literatura científica dos últimos 10 anos sobre a avaliação da qualidade de selamento e resistência à fratura de materiais obturadores endodônticos. A pesquisa foi conduzida em bases de dados como PubMed e SciELO e no motor de busca Google Scholar, utilizando termos chave específicos para garantir a abrangência e precisão dos resultados.
Verifica-se que nenhum tipo de cimento ou técnicas de obturação analisadas evita a microinfiltração apical ou aumente bastante a resistência à fratura pelo que há uma necessidade séria de investir mais em pesquisas e tentar reunir todas as características ideais do cimento, uma vez que não existe um cimento endodôntico ideal para o selamento do canal.
Contudo, é de salientar que não se encontra na literatura nenhum estudo que avalie todos os tipos de materiais obturadores disponíveis pelo que não é possível inferir qual deles é realmente o que apresenta melhor selamento apical ou maior resistência à fratura em relação a todos os outros. De acordo com esta revisão, os cimentos à base de resina são atualmente o único material mais próximo de um cimento ideal; no entanto, as biocerâmicas também mostram muita promessa. Também a introdução de nanoparticulas nos materiais obturadores pode ser um passo promissor para se obter um cimento ideal.
The success of endodontic treatment depends on cleaning and conformation and subsequent filling of the root canals, with the aim of obtaining an optimal hermetic seal, in order to avoid endodontic failure. To do this, it is necessary to combine solid and plastic materials, so that their combination is as biocompatible as possible with biological tissues. This study presents a comprehensive narrative review of the scientific literature over the past 10 years on the evaluation of sealing quality and fracture resistance of endodontic obturation materials. The search was conducted in databases such as PubMed and SciELO and in the Google Scholar search engine, using specific key terms to ensure the comprehensiveness and accuracy of the results. It is verified that no type of cement or filling techniques analyzed avoids apical microinfiltration or greatly increases fracture resistance, so there is a serious need to invest more in research and try to gather all the ideal characteristics of cement, since there is no ideal endodontic cement for canal sealing. However, it should be noted that there is no study in the literature that evaluates all types of available filling materials, so it is not possible to infer which one is really the one that presents the best apical sealing or greater fracture resistance in relation to all the others. According to this review, resin-based cements are currently the single material closest to an ideal cement; However, bioceramics also show a lot of promise. Also, the introduction of nanoparticles in filling materials can be a promising step towards obtaining an ideal cement.
