The results of the Amplex Red assay to detect generation of ROS. Data are presented as mean and standard error of the mean. The concentration of filtered composite dust (X-axis) is expressed in μg/ml. The numbers above the bars indicate statistically significant differences compared to the control (1: p < 0.05; 2: p < 0.01 and 3: p < 0.001). The black dotted line in each diagram indicates the level of non-treated cell controls. Only the highest concentrations of composite dust increased the generation of ROS, especially for GrandiO, Z100 and Filtek Supreme. However, compared to the positive control with Zymosan, which was included as a measure to indicate the capability of the cells to generate H2O2 as DQ12 quartz is not a positive control in this test, the release after composite-dust exposure was still more than 10 times lower
