Figure 1.

(a) Mouse fibroblast 3T3/NIH cytotoxicity after 24 h stimulation with white mineral trioxide aggregate or dual-cure mineral trioxide aggregate eluates. Control group was incubated with Dulbecco's modified essential medium supplemented with fetal bovine serum and antibiotics. No statistical difference was found between groups. (b) Human pulp fibroblast viability after stimulation with eluates (24 h) from white mineral trioxide aggregate or dual-cure mineral trioxide aggregate. Control group was incubated with Dulbecco's modified essential medium supplemented with fetal bovine serum and antibiotics. Mean and standard deviation was based on at least three independent experiments. Results were shown as mean ± standard deviation (shown by bar). Different letters indicate statistical difference (P < 0.05)
