The aim of this study was to evaluate the effect of exposed to differents means on water sorption and solubility of three composite resin. Specimens of each composite were andomly divided in 12 groups (n=10 per group): G1 (Control): no agents; G2: cigarette smoke; G3: coffee beverage; G4: wine beverage; G5: essential oils mouthrinse; G6: smoke/coffee; G7: smoke/wine; G8 smoke/mouthrinse; G9: smoke/coffee/mouthrinse; G10: smoke/wine/mouthrinse; G11: coffee/mouthrinse; G12 wine/mouthrinse, during 28 days. For evaluation of sorption and solubility, the specimens were stored in a laboratory desiccator until the attainment of constant initial mass (M-1). After exposition to the differents means, all specimens were placed in distilled water and reweighed (M-2) and stored again in the desiccator for constant mass evaluation (M-3). The results showed higher values of water sorption for Filtek Z350 XT (3M/ESPE) brand, whereas the solubility was most significant for IPS Empress Direct (IvoclarVivadent) when exposed to the association of smoke, coffee and mouthrinse (G9). Exposure to coffee and mouthrinse (G11) increased significantly sorption; however the exposure to coffee and its associations showed less solubility for all tested composite resins. It can be concluded that differents agents commonly used by patients can interfere in the diffusion process.
