Mineralization of dental tissues and caries lesions detailed with Raman microspectroscopic imaging

Abstract: Dental caries is the most common oral disease that causes demineralization of enamel and later in dentin. The depth-wise assessment of the demineralization process could be used to help treatment...

“…This article has been limited to the application of the Raman microprobe to point-based analyses, but uncoated polished sections such as lead pipe cross-sections offer the possibility of Raman mapping. Maps can be constructed on the basis of phase identity and/or selected characteristics (e.g., degree of crystallinity, solid solution, physical intergrowth) within individual grains while displaying them in their spatial context [31,68,69]. The confocal nature of many modern Raman systems even permits a form of depth-controlled, non-destructive microtomography under appropriate optical conditions (e.g., Schiavi et al's (2020) [68] multi-mineral inclusions).…”

“…The mineral composition is not homogeneous within sound enamel tissue; however, more crystallinity (greater mineral crystal size) and greater mineral crystal perfection are observed towards the tooth surface, whereas the mineral apatites are less crystalline and have more carbonate imperfection in the crystal lattice near the enamel-dentin junction [78]. Moreover, enamel has less substituted lattice compared to dentin, indicating the presence of mineral crystals with greater stoichiometric perfection in enamel when compared to dentin [78].…”

“…Das Gupta et al reported RMS chemical maps of enamel and dentin caries infiltration [78]. The enamel lesions appeared to be less mineralized due to more substituted carbonate in the crystal lattice compared to the sound enamel.…”

“…When Raman spectroscopy is used in combination with PCA [9,[16][17][18][19][20][21] or other MVA [9,[19][20][21][22] methods, it is possible to obtain unique spectral characteristics extracted from raw acquired spectra, which can be used for the identification of similar areas, specific features, or certain types of samples, along with differentiation and classification of a different sample or tissue condition, according to the case. Raman spectroscopy and PCA can be used to distinguish control from treated enamel samples [23], as well as to discriminate sound enamel from severe dental fluorosis samples with high levels of sensitivity and specificity [16].…”
