  • Title: Local study of fissure caries by Fourier transform infrared microscopy and X-ray diffraction using synchrotron radiation.
    Author: Seredin P, Kashkarov V, Lukin A, Ippolitov Y, Julian R, Doyle S.
    Journal: J Synchrotron Radiat; 2013 Sep; 20(Pt 5):705-10. PubMed ID: 23955033.
    Abstract:
    Investigations of intact dental enamel as well as carious-affected human dental enamel were performed using infrared spectromicroscopy and X-ray diffraction applying synchrotron radiation. Caries of enamel was shown to be characterized by an increase in the number of deformation and valence vibrations for N-C-O, N-H and C=O bonds, a decrease of the crystallinity index, and by the absence of the preferable orientation of hydroxyapatite crystals within the affected enamel. This indicates the presence of destructive processes in the organic matrix of hard tooth tissues.
