Teeth fluorescence measurements are widely used in teeth decay researches, but less in clinical practice. The fluorescence spectrum strongly depends on many experimental factors. 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.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
