%X Aim The aim of this study was to assess the physicochemical characterization and mineralization of nanofibrous scaffold incorporated with nanohydroxyapatite (nHA) and aspartic acid (Asp) for dental mineralization.  Methodology Three nanofibrous scaffolds were prepared, namely polycaprolactone (PCL), PCL with nHA, and PCL with nHA and Asp. Each scaffold was prepared separately by electrospinning. The physicochemical characterization of the surface of the nanofibrous scaffold was imaged using a scanning electron microscope (SEM), energy dispersive X-ray Analysis (EDX), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR). In vitro mineralization studies were performed by immersing the sample in simulated body fluid (SBF) for 7, 14, and 21 days. The surface of the samples was observed under SEM with EDX. Results SEM analysis of PCL/nHA/Asp revealed that the nanofibers were bead-free, smooth, randomly oriented, and loaded with Asp. The EDX spectra of PCL/nHA/Asp composite nanofibrous scaffold revealed broad peaks and corresponded to the amorphous form, while the sharp peaks corresponded to the specific crystalline structure of nHA. FTIR analysis showed specific functional groups corresponding to PCL, nHA, and Asp. The scaffolds incorporated with Asp exhibited higher mineralization potential with an apatite-like crystal formation, which increased with an increase in the duration of immersion in SBF. Conclusion Physiochemical characterization demonstrated the incorporation of PCL/nHA/Asp in the electrospun nanofibrous scaffold. The mineralization analysis revealed that the presence of Asp enhanced the mineralization when compared with the PCL and PCL/nHA. PCL/nHA/Asp incorporated in scaffold can be a promising material for dental mineralization.
