Abstract:
The tooth enamel must present a Raman spectrum with strong polarization anisotropy. Carious lesions of the enamel will produce an alteration of local symmetry and will increase much more scattering of light. This will reduce the anisotropy of the Raman spectra. The 959 cm-1 Raman peak has a high sensitivity to polarization in sound enamel and low sensitivity in carried enamel. Thus, Raman polarized spectroscopy could be a useful method to help fluorescence measurements in early detection of teeth caries.
