Spectroscopic signature of the pathological processes of carious dentine based on FTIR investigations of the oral biological fluids

Abstract: The aim of our work is to find a spectroscopic signature of the pathological processes of carious dentine based on the investigations of the molecular composition of the oral biological fluids with the use of FTIR synchrotron techniques. This complex analysis of the obtained data shows that a number of signatures are present only in the spectra of dentine and gingival fluids from the patients developing caries of the deep dentine tissues. The detected features and complex analysis of the quantitative and quali… Show more

“…Raman spectroscopy is most often used for diagnostics of dental diseases as a non-destructive method of analysis, which allows to obtain direct data regarding the local atomic structure, chemical and molecular composition of biological objects 18,20,24,[27][28][29] . Also, the hard tissue of a human tooth can be investigated by infrared spectroscopy methods [30][31][32][33][34] , which due to minimal external influences, has not been modified by the method 35 .…”

“…The use of infrared microspectroscopy with synchrotron radiation makes it possible to clarify the molecular composition and study local changes in the mineral-organic matrix of dental enamel from the areas less than 10 µm 2 39 . Moreover, in any case the applicability of synchrotron IR-microspectroscopy to the dental tissue analysis is more convenient than Raman microspectroscopy, even though the Raman microscopy is also an excellent approach to vibrational spectroscopy, with an equivalent, or often a better, spatial resolution than synchrotron infrared microscopy 31 , 33 , 37 , 40 .…”

“…As a consequence, many works have proposed the FTIR technique as a complementary spectroscopic method to support diagnostic investigation of cytological samples [1][2][3][4][5]. In addition, FTIR has also been considered in clinical practice for biological tissues [6][7][8] and biofluids [9][10][11] analysis, as well as to monitor the response of cells and tissues to radiotherapy [12] and chemotherapy [13] treatments.…”
