Aim: The aim of the present in vitro study was to determine the influence of three different storage media on the fluorescence behavior of carious lesions over a period of four weeks. In addition, the classification of the fluorescence readings was examined for its evidence according to the literature. Furthermore, the correlation between the fluorescence-based measurement using the VistaCam iX® (VC iX) and the visual findings of the International Caries Detection and Assessment System (ICDAS)

... as investigated. Materials and methods: The 72 extracted posterior teeth were carefully cleaned and evaluated by using the ICDAS codes. According to these codes, an equal number of teeth was then assigned to each of the three storage groups (distilled water, chloramine-T, freezing at -20 °C). The teeth were measured at baseline, after one week and after four weeks using the VC iX and its corresponding proof interchangeable head. The determined data was transferred to a spreadsheet program (MS Excel) and statistically evaluated using MedCalc version 19.1.7. The correlation between the findings of the ICDAS examination and those of the fluorescence measurement were listed in cross tables and evaluated with the rank correlation coefficient in accordance with Spearman (rs). The Kruskal-Wallis test and the Friedman test were used to evaluate whether there were differences between the individually measured values overall and the individual bearing groups over time. The results were presented and evaluated in Bland-Altman diagrams and box plots. Results: The correlation of the visual findings (ICDAS) with the fluorescence-based measurements (VC iX) is statistically significant positive in a high range (rs = 0.76). As for the individual storage media, a positive, partially high significance between the results is apparent: distilled water (rs = 0.85), chloramine-T (rs = 0.77), freezing at -20 °C (rs = 0.69). The evaluation of the Kruskal-Wallis test does not show significant differences in the VC iX measurement results between the [...]
