dc.description.abstractThe aim of this study was to evaluate the cohesive strength (CS), surface roughness (Ra), and weight loss (WL) of different composite resins. Three composite resins (Filtek Z100; Filtek Z350; Filtek P90, 3M ESPE) were tested. To evaluate CS, an hourglass silicone mold (11 x 2 x 1 mm) was used (n = 10). The Ra and WL tests were performed using a circular mold (5 x 2 mm, n = 10). The composite resins were light-cured with an LED light curing device (FreeLight 2, 3M ESPE) for 40 s and 1000 mW/cm(2). The CS test was performed using a universal testing machine (Instron 4411, Instron) at a crosshead speed of 0.5 mm/ min and cell load of 500 N. The initial mass weight was registered (analytical digital balance) and the initial Ra reading evaluated using a profilometer (Surftest 211, Mitutoyo). The specimens were submitted to 30,000 brushing cycles. The WL and the final Ra were evaluated. All data were subjected to one-way ANOVA, followed by Tukey's test (p < 0.05). Filtek Z100 showed the highest values of Ra and Filtek Z350 the lowest values of Ra. When considering CS, Filtek Z350 and Z100 had the highest mean values. Filtek P90 had the highest mean value of WL. The organic matrix and the type, shape, and size of fillers may influence the physicochemical properties of composite resins.en
dc.description.abstractO objetivo deste estudo foi avaliar a resistência coesiva (CS), rugosidade superficial (Ra) e perda de peso (WL) de diferentes resinas compostas. Três resinas compostas (Filtek Z100; Filtek Z350; Filtek P90, 3M ESPE) foram testadas. Para avaliação da SC, foi utilizado molde de ampulheta de silicone (11 × 2 × 1 mm) ( n = 10). Os testes de Ra e WL foram realizados em molde circular (5 × 2 mm, n = 10). As resinas compostas foram fotopolimerizadas com um fotopolimerizador LED (FreeLight 2, 3M ESPE) por 40 se 1000 mW / cm 2. O teste de CS foi realizado em uma máquina de teste universal (Instron 4411, Instron) a uma velocidade da cruzeta de 0,5 mm / min e carga de célula de 500 N. O peso de massa inicial foi registrado (balança analítica digital) e a leitura Ra inicial avaliada usando um perfilômetro (Surftest 211, Mitutoyo). Os corpos-de-prova foram submetidos a 30.000 ciclos de escovação. O WL e o Ra final foram avaliados. Todos os dados foram submetidos à ANOVA de um fator, seguida do teste de Tukey ( p <0,05). Filtek Z100 apresentou os maiores valores de Ra e Filtek Z350 os menores valores de Ra. Ao considerar CS, Filtek Z350 e Z100 apresentaram os maiores valores médios. Filtek P90 teve o maior valor médio de WL. A matriz orgânica e o tipo, forma e tamanho das cargas podem influenciar as propriedades físico-químicas das resinas compostas.pt_BR
