The aim of the study is to study the spectral characteristics of the hard tissues of the tooth, their Raman-fluorescent components (RFS) and to determine the possibility of using the method to assess the degree of mineralization of hard tissues of the tooth. In a preclinical study on model test objects of different functional groups of teeth (incisors, premolars, molars), remote by clinical indications, Raman-fluorescence spectroscopy was performed using the laser hardware-software complex “Inspector M” with a wavelength of probing radiation 514 nm. In the course of the study, a qualitative and quantitative analysis of the content and distribution of hydroxyapatite in the structures of hard dental tissues (enamel, dentin, cement) in normal and pathological conditions was performed. The high sensitivity and expressiveness of the method, the possibility of quantitative processing of the results of the study, which allows us to recommend it for assessing the degree of mineralization/demineralization of the tooth, the effectiveness of remineralizing drugs and methods of their use in the clinic of therapeutic dentistry.
