Avaliação do manchamento e da rugosidade superficial de materiais restauradores diretos após diferentes sistemas de polimento: estudo in vitro

Abstract: Resumo Introdução Com o avanço estético e tecnológico dos compósitos restauradores diretos, a procura pela Odontologia Éstética tem aumentado. Objetivo Avaliar o manchamento e a rugosidade superficial dos compósitos Filtek Z350 (3M ESPE) e Filtek Bulk Fill (3M ESPE), polidos por diferentes sistemas: Disco SofLex e Disco SofLex diamantado espiral (ambos da 3M ESPE), após exposição repetitiva ao café. Material e método Neste estudo in vitro, um total de 80 discos de resina foi confeccionado, com 40 espécim… Show more

“…Thus, these findings corroborate with the research of Gönülol , Yilmaz 22 , who verified in their study higher values of roughness in nanocomposites when using diamond burs before other polishing systems, this fact can be explained by et al 9 who viewed similar behavior between Filtek Z350 and Filtek bulk-fill polished with SOF-lex, probably due to the presence of aluminum oxide incorporated into this system and the similar composition of both resins.…”

“…Single-fill or bulk-fill resins appear on the market as an alternative for extensive subsequent restorations, due to the possibility of working with relatively large increments of approximately 4-5 mm 8,9 . The low degree of contraction presented as a result of polymerization is what makes it possible to use this technique, making secondary properties as a cavitary configuration factor (factor C) and the incremental technique that are both diffused among the conventional resins [10][11][12][13][14] .…”

“…Sabese que as resinas compostas apresentam sorção à água e concedem a integração de pigmentos da dieta em sua matriz. Para tanto, associando ainda o uso de um adequado material restaurador, ele deve exibir excelente acabamento e polimento, pois quando realizado adequadamente, minimiza as porosidades e consequentemente, dificultam a variação de cor destes materiais (Almeida et al, 2019).…”

“…Barutcigil et al 47 afirmaram que após a imersão em bebidas e a longo prazo, as cores das resinas compostas bulk-fill pesquisadas mudaram significativamente. Já no trabalho de Almeida et al 48 , dentre os compósitos analisados, a resina bulk-fill avaliada apresentou menor manchamento após a exposição ao café, independentemente do sistema de polimento utilizado.…”
