The results of expanded spectral analysis of donor dentin materials with the use of Raman spectroscopy method are presented in the work. The mathematical methods of improving the resolution of spectral contours and the chemometric analysis were used for estimation of the component composition of dentin materials during their demineralization.
The results of experimental study of samples of dental tissues affected by periodontitis using Raman spectroscopy method are presented in the work. Spectral changes are detected in hard dental tissues affected by periodontitis. The main spectral changes are seen in the wavenumbers of 956 cm-1, 1236 cm-1, 1269cm-1 and 1663 cm-1, owing to the change of mineral-protein components in case of periodontitis.
