“…Another study (20) revealed differences between sound enamel and initial caries at the peak of HA, disagreeing with the findings of this study in that the ~960 cm -1 peak in enamel caries and sound enamel had no significant difference.…”

The aim of this work was to verify the existence of correlation between Raman spectroscopy readings of phosphate apatite (~960 cm -1 ), fluoridated apatite (~575 cm -1 ) and organic matrix (~1450 cm -1 ) levels and Diagnodent ® readings at different stages of dental caries in extracted human teeth. The mean peak value of fluorescence in the carious area was recorded and teeth were divided in enamel caries, dentin caries and sound dental structure. After fluorescence readings, Raman spectroscopy was carried out on the same sites. The results showed significant difference (ANOVA, p<0.05) between the fluorescence readings for enamel (16.4 ± 2.3) and dentin (57.6 ± 23.7) on carious teeth. Raman peaks of enamel and dentin revealed that ~575 and ~960 cm -1 peaks were more intense in enamel caries. There was significant negative correlation (p<0.05) between the ~575 and ~960 cm -1 peaks and dentin caries. It may be concluded that the higher the fluorescence detected by Diagnodent the lower the peaks of phosphate apatite and fluoridated apatite. As the early diagnosis of caries is directly related to the identification of changes in the inorganic tooth components, Raman spectroscopy was more sensitive to variations of these components than Diagnodent.

“…In refs [5] the authors assess the ratio of crosspolarised (the polarisation of scattered light is perpendicular to that of the incident light) and copolarised Raman spectra at 959 cm -1 . It was found that the ratio of co-and cross-polarised Raman scattering intensities can be used to assess the degree of demineralisation.…”

Abstract. The object of study were human teeth with caries cavities and healthy teeth extracted for orthopaedic indications. The main method of study was Raman spectroscopy. We revealed the specific features of Raman spectra for the healthy tooth tissues impaired ones and the tissues affected by caries. The optical criteria are established that allow cares detection and assessment, as well as the detection of precaries impairment of the tooth tissues. The results were analysed in comparison with the data of the chemical analysis performed using a raster electron microscope.

“…Studies generally are focused on the phosphate peak from carbonate hydroxyapatite and how biochemically is affected by de-and remineralization. Nowadays this studies are used ininvestigation only in ex vivo experiments by measurements on sound and carious enamel and was found high sensitivity of 100% and specificity 98% [53]. The early changes in the spectrum are mainly due to both the de-and remineralization of the tooth hard tissues and the change in the mineral component.…”

“…In addition, like OCO, PRS measures light scattering and as with other emerging optical methods, the properties of the scattering light within sound and carious regions are explored to determine their use in caries detection [59,60].…”

Nowadays it is apparent that the conventional methods for early caries detection do not fulfill the criteria for the ideal clinical methods (and also to be used in scientific studies). In this regard they are subjective and insensitive. In this point it is of paramount importance to develop novel detecting techniques, which will be promising quantitative detecting methods of early caries lesions. In this assumption there are new technologies and devices for detection and diagnosis of dental lesions at their early stages of formation, evaluating their activity with higher sensitivity and specificity. Some of these devices are developed and commercially available, others are still under development. Consequently, there some creative contemporary methods and devices with great theoretical impact and exceptional practical preferences as diagnostic techniques and methods are presented: i/ the technique of optical coherence tomography (OCT), ii/ polarized Raman spectroscopy (PRS).
