Effect of resin thickness on the microhardness and optical properties of bulk-fill resin composites

Abstract: ObjectivesThis study evaluated the effects of the resin thickness on the microhardness and optical properties of bulk-fill resin composites.MethodsFour bulk-fill (Venus Bulk Fill, Heraeus Kulzer; SDR, Dentsply Caulk; Tetric N-Ceram Bulk Fill, Ivoclar vivadent; SonicFill, Kerr) and two regular resin composites (Charisma flow, Heraeus Kulzer; Tetric N-Ceram, Ivoclar vivadent) were used. Sixty acrylic cylindrical molds were prepared for each thickness (2, 3 and 4 mm). The molds were divided into six groups for re… Show more

“…In attempt to reach these characteristics and with the increase in the demands made by patients for esthetic restorations, improvements in technology have led to the current development of resin-modified glass ionomer cement (RMGIC) and resin-based composite resins (RBC) 2) . A bulk-fill resin-based composites were introduced to reduce the time for placement of the restoration by allowing up to 4 mm thick increments to be cured in a single phase, thus allow timesaving of the layering process 3) . Flowable bulk-fill resinbased composites have easy-handling properties, lowviscosity, the capability to yield layers with reduced air trap and the excessive flexibility to be used as cavity liners 3,4) .…”

“…Considering that the thickness significantly affects the translucency, we chosen to use the changes on the TP observed in each specimen in the data analyses. 25,26 Changes on TP were observed only for the enamel, which became more opaque. The explanation for differences on TP changes between the hard tooth tissues evaluated is related to mineral content.…”

“…A figura 5.13 mostra o teste de Kruskal-Wallis para os resultados. Em geral, resinas bulk fill são mais translúcidas à luz azul 7,85 , já que foram desenvolvidas para polimerizar em grandes porções. Entretanto, a resina SonicFill (SF) apresenta translucidez comparável a compósitos convencionais, provavelmente devido à presença de partículas de carga de formato irregular e de tamanhos relativamente maiores 85 , o que diminui a transmissão de luz 128 .…”

“…O alto valor deste parâmetro nas resinas Venus Bulk Fill (VBF) e Surefil SDR (SDR) em comparação a compósitos bulk fill de alta viscosidade foi previamente comprovado 7 , e tal fato pode ter sido responsável pela conversão de 66,7% e 62,8%, respectivamente, nesses materiais. Entretanto, apesar do apelo para o uso de grandes volumes de material devido à alta translucidez de compósitos bulk fill, a polimerização de um compósito convencional translúcido a 4 mm de profundidade já foi reportada 132 .…”
