Abstract

The objective of study is evaluate the influence of the addition of 0.5%wt graphene oxide experiments on conversion degree (GC), sorption (So) and solubility (Sol), elastic modulus and flexural strength and the depth of penetrationcompared to commercial control and experimental control. The conversion degree (n=5) will be performed using infrared spectroscopy with Fourier infrared,being evaluated before and after the photoactivation of the material. So and Sol(n=10) will be done by performing dissections on the samples, weighing and storing them in distilled water for 7 days and weighing them until a constant mass is obtained. The modulus of elasticity and flexural strength (n=10) will beevaluated by the three-point method. To analyse the penetration depth (n=3), samples will be obtained from bovine teeth and treates in a demineralization solution during 32h, then they are going to be treated according to the groups,and evaluated by Confocal Scanning Laser Microscopy (MCVL). The data will be tabulated and tested with homogeneity, to determine the use of parametric or non-parametric tests, the significance level will be 5%.
