Structural differences in enamel and dentin in human, bovine, porcine, and ovine teeth.

Background: The aim was to study differences between crystalline nanostructures from the enamel and dentin of human, bovine, porcine, and ovine species.

Methods: Dentine and enamel fragments extracted from sound human, bovine, porcine and ovine incisors and molars were mechanically ground up to a final particle size of <100μm. Samples were analyzed using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC).
