All composites had the same organic matrix (40% wt) and photoinitiator system (1.2% wt). Experimental composite groups were divided according to ratio (%) of silanated ground glass (0.5 µm) (BaAlSi) and fumed silica (SiO2): 100/0, 90/10, 80/20, and 70/30. Light-emitting diode light was used in the continuous, soft-start, and pulse-delay modes (n = 10). Degree of conversion was determined using attenuated total reflectance-Fourier transform infrared spectroscopy. Flexural strength and modulus were obtained using a universal testing machine, and Knoop microhardness was measured in a Knoop indenter. The data were subjected to a two-way ANOVA and Tukey's post hoc test (a = 0.05). Continuous-light exposure of the 100/0 group produced the highest degrees of conversion. Soft-start exposure of the 70/30 groups produced the highest Knoop microhardness. The pulse-delay method produced the lowest flexural strength and modulus values. The 100/0 and 70/30 groups had the lowest flexural strength and flexural modulus, respectively. Application of continuous-light output with composite resins containing a ratio of 80/20 (BaAlSi/SiO2) fillers generated the best results regarding the degree of conversion and mechanical propertiesFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPFechadoUNIVERSIDADE ESTADUAL DE CAMPINASPrezotto, André Furlan da SilvaSinhoreti, Mário Alexandre Coelho, 1969-2019info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/20.500.12733/1657152PREZOTTO, André Furlan da Silva; SINHORETI, Mário Alexandre Coelho.
