The aim of the study was to evaluate the influence of photopolymerization,time of composite resin of the sorption and solubility properties of the material. It was used the Filtek, Z350 XT resin, shade A2B, the study was evaluated in four different timing of light curing (10s, 20s, 40s and 60s). Five resin discs were made per group, of 8mm x 1mm and prepared in accordance with ISO 4049. The water sorption and solubility were calculated using the formulas according to ISO 4049. The results were submitted to analysis of variance (ANOVA) where the time of 40s and 60s polymerization showed the lowest sorption values. The solubility showed no significant differences. With our data it can be concluded that 40S polymerization time must be observed to maintain the properties of the resin.
