Cell migration was evaluated using a scratch assay. Cells were maintained in 25% extraction medium from the different materials. The control condition was cells maintained in normal growth medium. a Representative images of the scratch areas. The red dot line represented the initial border of the edge of scratched wound. At day 1, cell migration beyond the reference line was observed in the control, ProRoot® MTA, and Biodentine™. b Graph illustrated the number of cells migrating from the edge at day 1. Asterisk designates significant differences compared with the control (Mann Whitney U test, p < 0.05)
