Cell proliferation after exposure to extracted medium. MTT assay was utilized to determine cell viability at day 1, 4 and 7. a The control condition was cells maintained in normal growth medium. The percentage of cell number at different time points after the hDPs were exposed to extraction medium from b DyCal®, c ProRoot® MTA, d Biodentine™, and e TheraCal™ LC. f Doubling time was calculated using formula previously described. Bars indicate a significant difference (Kruskal Wallis test followed by pairwise comparison, p < 0.05)
