Resumo: | ABSTRACTObjective: This study aimed to assess the bond strength and marginal microleakage in composite resin restorations, using the Single Bond Universal adhesive system associated with Ultralux (halogen) and Bluephase (LED) light curing units.Methods: For bond strength, 80 healthy human third molars were divided into halogen light (n=40) and LED (n=40), and subdivided according to the following application techniques for the adhesive system: etch-and-rinse (enamel), self-etching (enamel), etch-and-rinse (dentin), and self-etching (dentin). The teeth were subjected to the microtensile test and the fracture pattern was observed under an optical microscope at 40X magnification; they were analyzed by ANOVA, and Fisher and Tukey’s tests (5%). For the marginal microleakage test, 120 class II cavities were prepared in 60 healthy human third molars that were randomly divided into halogen light (n=30) and LED (n=30), and subdivided according to the following application techniques for the adhesive system: etch-and-rinse, selective etching, and self-etching. The teeth were thermocycled 2000 times (±5/55°C), stained in 5% basic fuchsin and sectioned for qualitative and quantitative assessments; they were analyzed by Kruskall-Wallis and Dunn tests (5%).Results: For the bond strength of enamel and dentin, the adhesive application with prior acid etching was better than self-etching (p<0.0001), regardless of the type of light curing unit (p<0.05). Etch-and-rinse showed the lowest microleakage values (p<0.0001).Conclusion: Etch-and-rinse obtained the best results relative to the other application techniques for the adhesive system in both tests, regardless of the type of light curing unit. |

Os dentes foram submetidos ao teste de microtração e o padrão de fratura foi observado em microscópio ótico – 40X de aumento, analisadas pelos testes ANOVA, Tukey e Fisher (5%). Para o ensaio de microinfiltração marginal, 120 cavidades classe II foram preparadas em sessenta terceiros molares humanos hígidos, aleatoriamente divididos: Halógena (n=30); LED (n=30) e subdivididos de acordo com a técnica de aplicação do sistema adesivo: condicionamento total; condicionamento seletivo; autocondicionante. Os dentes foram termociclados 2000 vezes (±5/55ºC), corados em fucsina básica 5% e seccionados para avaliações qualitativa e quantitativa, analisados pelos testes Kruskall-Wallis e Dunn (5%).Resultados: Para resistência de união em esmalte e dentina, a aplicação do adesivo com condicionamento ácido prévio, foi melhor que o autocondicionante (p<0.0001), independentemente do tipo de fotoativador utilizado (p<0.05). O condicionamento total mostrou os menores valores de microinfiltração, (p<0.0001).Conclusão: O condicionamento total, obteve os melhores resultados em relação às outras técnicas de aplicação do sistema adesivo em ambos os testes, independentemente do tipo de aparelho fotoativador.Universidade Estadual do Oeste do Paraná Pós-Graduação em OdontologiaUniversidade Estadual PaulistaUniversidade Estadual PaulistaFaculdade São Leopoldo MandicUniversidade Estadual do Oeste do Paraná Pós-Graduação em OdontologiaUniversidade Estadual Paulista (Unesp)Ricardi, Felipe De BrumBusato, Mauro Carlos AgnerBusato, Priscilla Do Monte RibeiroMendonÇa, Márcio JoséRosa, Saulo Vinicius DaMarchi, Paulo Guilherme Bittencourt2019-10-03T17:31:45Z2019-10-03T17:31:45Z2019info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article-application/pdfhttp://dx.doi.org/10.1590/1981-86372019000313586RGO - Revista Gaúcha de Odontologia.
