dc.description.abstractIn the present study was observed the influence of gamma radiation in thermal and mechanical properties of the experimental dental composites based on BISGMA/TEGDMA filled with pre-irradiated MMT nanoparticles (Cloisite® 20A). MMT nanoparticle was pre-irradiated at doses of 10, 15 and 70 kGy. As a control group MMT nanoparticle was added in the polymeric matrix without pre-irradiation. Four formulations of experimental nanocomposites were studied all with 50% wt of filler. The characterization of the experimental composites was performed by means of the following techniques: Thermogravimetry Analysis (TGA), Elastic Modulus and Flexural Strength. It was observed that the group filled with pre-irradiated nanoparticles at dose of 70 kGy showed a delay in the decomposition temperature when compared to the control group. For elastic modulus the results showed a proportional increase related to the dose of radiation applied in the MMT nanoparticle. Regarding flexural strength, the groups filled with pre–irradiated nanoparticles and the control group presented similar results.pt_BR
