Summary
PURPOSE: The present study was conducted to determine oxidative stress and cell viability after contact with resin composites polymerized for different times. METHODS: DCF-DA), and the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, respectively. RESULTS: At 72 h, ROS production in the presence of Admira Fusion polymerized for 40 s was reduced relative to that in the presence of Admira Fusion polymerized for 20 s (P < 0.05). Cell viability was maximal in the Admira Fusion and Solare x groups and there was no difference relative to the control group at 48 h. Cell viability was higher in the Admira Fusion and Solare x groups polymerized for 40 s than for the same materials polymerized for 20 s at 72 h (P < 0.05). CONCLUSION: Extension of the polymerizaton time has a material-specific effect and may be used as a strategy to increase the biocompability of resin composites.
