The aim of this study was to evaluate the biological effects of bioactive glass-containing self-adhesive resin cements (SARCs) on human dental pulp stem cells (DPSCs), focusing on cytocompatibility, odontogenic differentiation, and mineralization. Experimental SARCs containing 0–5 wt% BAG (BG0–BG5) were compared with two commercially available SARCs, RelyX U200 and TheraCem. Eluates were prepared and applied to DPSCs for the methylthiazol tetrazolium (MTT) assay, quantitative real-time polymerase chain reaction (qRT-PCR), immunofluorescence (IF) staining, and Alizarin Red S (ARS) staining. The result showed there were no significant differences in cell viability across all groups (p > 0.05), indicating that the addition of BAG did not affect cell viability, while the early odontogenic differentiation markers, such as RUNX2, ALP, and COL1A1, showed no clear trend among the groups. However, late-stage markers (DMP-1 and DSPP) were significantly higher in the BG2–BG5 groups relative to the OM group (p < 0.05). IF staining revealed intense signals in the BG2–BG5 groups (p < 0.05) and also ARS staining showed a time-dependent increase in mineral deposition. Within the limitations of this study, BAG-containing SARCs do not negatively impact cytocompatibility and promote late-stage odontogenic differentiation and mineral deposition.
