Abstract Background The purpose of this prospective clinical diagnostic study with validation was to compare the diagnostic accuracy of near-infrared transillumination (NIRT), laser fluorescence measurement (LF), alternating current impedance spectroscopy (ACIS) and their combinations as adjunct methods to visual examination (VE) for occlusal caries detection using a hybrid reference standard. Methods Ninety-six first and second non-cavitated permanent molars from 76 individuals (mean age 24.2) were investigated using (VE) (ICDAS) and bitewing radiography (BWR), as well as NIRT, LF and ACIS. The findings of BWR and NIRT were evaluated by two examiners while the other examinations were conducted by one calibrated dentist. The hybrid reference standard consisted of non-operative validation based on the results of VE and BWR and operative validation. Statistical analysis included cross-tabulations, calculation of sensitivity, specificity and area under the receiver operating characteristic curve at three diagnostic thresholds: caries in general, enamel caries and dentin caries. Results NIRT, LF and ACIS exhibited high sensitivity for caries in general [1.00 (1.00–1.00), 0.77 (0.65–0.88), 0.75 (0.63–0.87)) and for dentin caries (0.97 (0.91–1.03), 0.76 (0.76–0.90), 0.64 (0.47–0.80)]. Sensitivity values for enamel caries were weak (0.21, 0.11, 0.37). Specificity values did not fall below 0.65 (NIRT) for all categories and methods, except for NIRT at the caries detection threshold (0.27). A combination of LF and ACIS with VE improved the diagnostic performance at the overall and the enamel caries threshold. The other methods showed fair to excellent discrimination at the overall caries threshold (NIRT 0.64, LF 0.89 and ACIS 0.86) and acceptable discrimination at the dentin caries threshold (NIRT 0.82, LF 0.81 and ACIS 0.79). AUROC for enamel caries exhibited the weakest discrimination. Accuracy was 65.6% for VE, 69.8% for BWR, 50.0% for NIRT, 53.1% for LF and 74.0% for ACIS. Reliability assessment for BWR and NIRT showed at least substantial agreements for all analyses. Conclusions The methods, NIRT, LF and ACIS, revealed different potential but no impeccable performance for occlusal caries detection. All are suitable instruments to detect hidden carious lesion in dentin. As auxiliaries to VE, LF and ACIS showed an increase in diagnostic performance.

Early detection of occlusal caries in children is challenging for the dentists, because of the morphology of pit and fissures. The aim of this study was to compare in vitro the diagnostic performance of low-powered magnification with light-emitting diode headlight (LPMLED) using ICDAS-II criteria and AC Impedance Spectroscopy (ACIS) device, on occlusal surfaces of primary molars. The occlusal surfaces of 18 extracted primary molars were examined blindly by two examiners. The teeth were sectioned and examined under light microscopy using Downer’s histological criteria as gold standard. Good to excellent inter- and intraexaminer reproducibility, higher sensitivity, specificity, and AUC values were achieved by LPMLED at D1 threshold. Also the relationship between histology and LPMLED was statistically significant. In conclusion visual aids have the potential to improve the performance of early caries detection and clinical diagnostics in children. Despite its potential, ACIS device should be considered as an adjunct method in detecting caries on primary teeth.

Objective: This study aimed to investigate the association of two fluorescent dyes and Laser Fluorescence (LF) device in detecting smooth and occlusal natural caries in primary teeth in vitro.Methods: Measurements were performed with the LF and with LF associated with tetrakis (N-methylpyridyl)porphyrin (LF TMPyP) and protoporphyrin IX (LF PPIX) in 72 smooth (63 primary molars) and 134 occlusal sites (81 primary molars). For validation, surfaces were sectioned and sections obtained were evaluated under stereomicroscope. Smooth surfaces were also evaluated using polarized light microscopy and Knoop microhardness. For both smooth and occlusal surfaces, ROC analyses were performed, and sensitivities, specificities and accuracies were assessed. In smooth surfaces, Pearson’s correlation coefficients between LF values and lesions hardness or lesions depth were calculated.Results: LF TMPyP presented higher correlation with hardness and lesion depth than other methods in smooth surfaces. No differences were observed in other parameters among the methods, in both smooth and occlusal surfaces.Relevance: The LF TMPyP might improve performance in quantifying smooth-surface caries lesions in primary teeth. However, the sensitivity is improved at D2 (caries extending into inner half of the enamel but not to amelodentinal junction) threshold when using PPIX in smooth caries lesions. The association of LF with fluorescent dyes does not improve the performance on occlusal caries.
