Raman-Fluorescent Characteristics of Different Anatomical and Topographic Zones of Teeth of Different Functional Groups

Abstract

The aim of the study is to study the state of mineralization of various anatomical and topraphic zones of teeth for different functiona I groups and to justify its clinical feasibility. In a preclinical in vitro study on 20 model test objects of teeth (incisors, canines, premolars and painters), removed according to clinical indications, Raman-fluorescent study of the degree of mineralization of various anatomical and topographic zones of the tooth in different functional groups of teeth was carried out. Used APC Inspector M with a wavelength of532 nm probing radiation. The advantages of Raman fluorescence spectroscopy for determining the degree of mineralization of hard tooth tissues are objectivity (digital technology), expressiveness, non-invasiveness, simple and non-destructive control of the degree of mineralization/remineralization of hard tooth tissues, the ability to document and store information. In th e course of the study, a qualitative and quantitative analysis of the mineralization of various anatomical and topraphic zones of teeth for different functional groups of teeth was carried out. High sensitivity and reproducibility of the method allowed to reveal significant differences in mineralization of tooth enamel in the area of the cutting edge, equator and neck of the tooth. It is shown that these differences are manifested in other functional groups of teeth (p < 0.05).
