--- In this study was evaluated the in vitro surface microhardness from two restorative materials; FILTEK Z350XT methacrylate and FILTEK P90 silorane resins. Ten cylinders were elaborated of 6mm diameter by 6mm high for each one of the materials used in this study, light cured by LED during 40 seconds to then be stored in distilled water at 37 degrees Celsius for 24 hours. Microhardness measurement was reach at all samples with a microdurometer applying a loading of 500g by 10 second, finally samples were observed in a microscope at 20x magnification. The data were subjected to the student t-test with a confidence level at 95%. The results showed that group of methacrylate composite Z350 XT had a superficial microhardness average of 86.40 Kg/mm2, while the group of silorane composite P90 showed microhardness average of 84.64 Kg/mm2. The data showed p = 0.0066 being statistically significant, between composites observed. Concluding that methacrylate composite presented higher microhardness value instead of silorane composite. Keywords: hardness, composites, silorane
