Deviations of inorganic and organic carbon content in hypomineralised enamel

Artikel i vetenskaplig tidskrift, 2015

Objectives: The purpose of this study was to discriminate hypomineralised enamel of permanent first molars from normal enamel by means of spectroscopic methods. Methods: The present study was conducted using Multi spot Raman Fourier Transform Spectroscopy, Diffuse Reflectance Infrared Fourier Transform Spectroscopy (FTIR) and X-ray diffraction (XRD). Results: Raman-spectroscopy indicated significantly more B-type carbonate and hydrocarbons in hypomineralised enamel diagnosed as MIH (Molar Incisor Hypomineralisation). From XRD analysis, no changes in crystallinity of the enamel apatite could be found. Conclusions: Using multi spot Raman-spectroscopy, a significant molecular discrimination between normal and hypomineralised enamel could be made.
