Viability of human dental pulp stem cells (hDPSCs) on the 2D culture dish and 3D CaP granules (a) without and (b) with the induction of odontogenic medium (50 μg/mL ascorbic acid, 10 mM β-glycerol phosphate, and 10−7 M dexamethasone). The cell viability in the culture dish was increased up to 14 days and maintained at 21 days, whereas that on the CaP granules was reduced at 21 days (statistical significant difference was noticed between 14 and 21 days in the CaP granules, **P < .01, ANOVA, n = 3). The odontogenic medium reduced the overall cell viability in both groups.
