Objective: The purpose of this study was to compare the effects of two fast-setting pulp-capping materials, Biodentine (BD) and iRoot Fast Set (FS) root repair material, on the attachment, viability, migration, and differentiation of human dental pulp stem cells (hDPSCs).
Methods: A comparative study was conducted between BD and FS material disks. Scanning electron microscope (SEM) images were used to observe the attachment of hDPSCs on the disks. A live/dead assay was used to assess the cell viability. Transwell assay was performed to study cell migration. Cell differentiation was determined by quantitative real-time polymerase chain reaction (qRT-PCR) for the analysis of osteogenic differentiation gene expression: alkaline phosphatase (ALP), collagen type I (COL1) and osteocalcin (OCN).
Results: SEM images indicated that hDPSCs showed a well-spreading morphology on both BD and FS disks. FS significantly increased the proliferation and migration of hDPSCs on day 7 (P<0.05). Neither BD nor FS promoted the expression of osteogenic genes during the observation period.
Conclusions: BD and FS both were beneficial to hDPSC attachment, and they had similar effects on cell osteogenic differentiation, whereas FS performed better than BD on hDPSCs proliferation and migration.
