Aim: The accurate and timely diagnosis of dental caries is an everyday challenge for dental practitioners. Due to caries decline, there is an increasing need for more subtle diagnostic methods able to e.g. detect initial lesions. In addition to visual inspection, several methods including radiography, laser or light fluorescence based techniques and electrical impedance measurements are available. The aim of this study was to assess the sensitivity and specificity of the fluorescence based

Material & Methods: 53 freshly extracted human teeth (47 molars, 6 pre-molars) were available for this study. Prior to extraction, informed consent had been obtained from the patients about the use of the teeth for research purposes. After the teeth had been cleaned, the occlusal surfaces were photographed and 1-3 investigation sites per surface were marked in the digital images (n=99). All investigation sites were visually inspected according to the ICDAS-II-criteria by two examiners. Afterwards, both examiners independently examined the teeth using the fluorescence based camera system VistaProof. For this purpose, digital images were taken and analyzed by the appropriate software. The teeth were then serially sectioned in a vestibulo-oral direction for the histological examination, resulting in 9-12 slices per tooth with a thickness of 300µm (± 30 µm) each. Lesion depth was assessed by both examiners using microscopy. Statistics: The statistical evaluation was carried out with SPSS, version 14.0. Correlation between the fluorescence measurements and the histological results was determined by means of Spearman's rank correlation coefficient. Sensitivity and specificity were assessed at D1- (enamel and d [...]
