Effects of Dental Methacrylates on Oxygen Consumption and Redox Status of Human Pulp Cells

Evaluation of subcytotoxic concentrations. HPCs were treated with different concentrations of monomers for 24 h. The viability was determined by MTT assay (a) and the number of viable cells was evaluated by trypan blue exclusion test (b). On the basis of the obtained results, the highest concentration of each monomer inducing a decrease of cell numbers less than 20% was selected. MTT results were reported as percentage of viable cells versus control ± SD. Trypan blue data were reported as cell number in 1 mL of DMEM. Data are the mean of 5 different experiments performed in quadruplicates ( ).
