Abstract Objective Under the condition of biomimetic conditions, organic macromolecular gelatin was used as a template to investigate the effects of different reaction durations on the morphological changes and arrangement of synthetic enamel-like fluoroapatite (FA) crystals. Methods A biomimetic material similar to the enamel-like structure, fluoroapatite (FA) crystal, was synthesized under the condition of biomimetic conditions (37℃, 1 atm, pH 6.0) using field emission scanning electron microscopy (SEM), X. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS) were used to characterize the crystal morphology and structure synthesized at different times. Results The crystal obtained by the synthesis was determined to be a FA crystal. As the reaction time prolongs, the morphology gradually changes from spherical particles to clusters of regular hexagonal prismatic rod-like crystals . Conclusion Under the bionic conditions, the surface morphology of enamel-like fluoroapatite synthesized by gelatin as template is more similar to natural enamel and the structure is more stable, so as to be used for the restoration of dental defects.
