Evaluation of cell viability of human dental pulp stem cells in two dimensional and three dimensional fibrin glue scaffold

CONTEXT: Regenerative endodontics uses the concept of tissue engineering to restore the diseased immature tooth, allowing for continued development of the root to a healthy state. For regenerative endodontics, the use of human dental pulp stem cells (HDPSCs) with appropriate scaffolds and growth factors is imperative. AIMS: The aim of the study was to evaluate the human dental pulp cell viability in two-dimensional (2D) and 3D fibrin glue scaffold to be used in regenerative endodontics. SUBJECTS AND METHODS: Regenerative potential of HDPSCs was comparatively assessed usings 2D and 3D fibrin glue scaffold. 3D scaffold was made with different concentrations of fibrinogen. Cell morphology was studied under inverted phase-contrast microscopy, and cell proliferation was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay at various time intervals. STATISTICAL ANALYSIS USED: value of the study was kept 0.05 according to the sample size. RESULTS: Study revealed a significant increase in the proliferation of HDPSCs in fibrin glue precoated wells of 2D fibrin glue compared to preseeded cells on day 1 and day 3. The concentration of fibrinogen has a major role in cell viability in 3D fibrin glue scaffold. Homing of HDPSCs in the 3D scaffold improves with time. CONCLUSIONS: This study concludes that the concentration of fibrin glue has a significant role in HDPSC Viability in 3D scaffold.
