Representative SEM micrographs illustrate the morphology of hDPs directly seeded on DyCal®, ProRoot® MTA, Biodentine™, and TheraCal™ LC at 3, 6, 24, and 48 h. Membrane blebbing and rupture were observed in DyCal® group. Cells seeded on ProRoot® MTA or Biodentine™ were able to attach and to spread on those materials. Cells on TheraCal™ LC exhibited membrane porosity
