Abstract(s)
Objetivo: Avaliar a resistência de união dos adesivos universais, aplicados pela técnica restauradora direta, aos substratos dentários.
Metodologia: Pesquisa bibliográfica efetuada nas bases de dados eletrónicas PubMed, ScienceDirect e ResearchGate. A pesquisa foi sujeita a critérios de inclusão e exclusão e os estudos foram selecionados seguindo os critérios PRISMA. A avaliação da qualidade metodológica dos artigos foi realizada de acordo com a escala de Onofre et al. (2014) modificada.
Resultados: Dos 196 artigos identificados foram selecionados 13 estudos. A resistência de união dos adesivos universais no esmalte apresenta melhores resultados com a abordagem Etchand-Rinse, enquanto que na dentina a estratégia de aplicação não afeta significativamente a resistência de união.
Conclusão: A evidencia dos estudos in vitro sugere que o condicionamento seletivo do esmalte previamente à aplicação do adesivo universal é aconselhável para otimizar a adesão neste tecido. A aplicação pela estratégia Self-Etch é o método de eleição para a dentina.
Objective: To evaluate the bond strength of universal adhesives applied by a direct restorative technique to dental substrates. Methodology: Literature search performed in electronic databases PubMed, ScienceDirect and ResearchGate. The search was subjected to inclusion and exclusion criteria and studies were selected following PRISMA criteria. Methodological quality of the articles was assessed according to the modified scale of Onofre et al. (2014). Results: Of the 196 articles identified, 13 studies were selected. The bond strength of universal adhesives in enamel shows better results with the Etch-and-Rinse approach, while in dentin the application strategy does not significantly affect the bond strength. Conclusion: Evidence from in vitro studies suggests that selective enamel etching prior to universal adhesive application is advisable to optimize bond strength in this tissue. Application by the Self-Etch strategy is the method of choice for dentin.
