Abstract

The purpose of this study will evaluate the mechanical behavior to compression of four composite resins fotopolimerizáveis found on the market: Charisma (Heraeus külsQ), Fill Magic (Vigodent), Brilliant (Vigodent), Z100 (3M). Will be up a total of 64 bodies of evidence, 16 for each matrix of resin with Teflon from 8mm in height by 4mm in diameter. These will be manufactured trim input of 4mm increments and light cured in accordance with the time specified by the manufacturer. For the tests will be used to machine Artificial Accelerated Aging for non-metallic and Máquina Universal de Ensaios MEM 2000 placed in LIPEM da Faculdade de Odontologia de Ribeirão Preto of Universidade de São Paulo and then later the results will be subjected to statistical analysis.
