The goal of this study was to evaluate the influence of a PVC Seal Wrap as barrier protection and the influence of autoclaving on the in vitro performance of a laser fluorescence device in detecting occlusal caries lesions in primary teeth. The clinical significance of the experiment is to create a protocol to avoid the possibility of underestimating caries in clinical setting.

Background: There has been an increased incidence of dental caries in children due to recent changes in lifestyle. More sensitive and reproducible diagnostic tools for precise caries detection in children are needed because of the complex occlusal anatomy. Aim: To compare the clinical performance and accuracy of international caries detection and assessment system-II (ICDAS II) versus DIAGNOdent pen and digital bitewing radiograph in the detection of occlusal caries in the primary teeth. Materials and Methods: Fifty children aged 6-11 years were assessed of both gender (29 girls and 21 boys) and 377 occlusal surface of primary teeth were examined by visual ICDAS II, DIAGNOdent pen and digital bitewing radiographic examination at D0 (non caries lesions), D1 (lesions limited to enamel) and D2 (lesions limited to dentin) thresholds. Results: Sensitivity at D0 for ICADS II was 14.23% and 95.95% for DIAGNOdent pen and 87.85% for digital bitewing, radiographs while specificity for both ICADS II and bitewing radiographs were 99.23% but 73.85% for DIAGNOdent pen. At D1, threshold sensitivity of ICADS II and digital bitewing radiographs were higher than DIAGNOdent pen but specificity for bitewing radiographs and DIAGNOdent pen 90.69% - 87.99%. were highly significant than ICADS II At D2, threshold specificity for all diagnostic methods was almost similar with better sensitivity for ICADS II and digital bitewing radiographs. Conclusion: This study showed that ICDAS II, Diagnodent pen, and bitewing radiography are effective for the detection of occlusal caries for primary molars. Digital bitewing radiography correlated stronger with ICDASII than Diagnodent pen and proved to be the best method to detect occlusal lesions within the dentin in primary molars while Diagnodent pen and bitewing radiography are better for detecting enamel caries lesion. In addition, the clinical performance of three diagnostic methods was insufficient to detect occlusal caries lesions separately. Consequently, it is advisable to use a combination of diagnostic methods, especially in unclear cases, as well as in cases of initial lesions and their monitoring.

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.

ABSTRACT Objective: To evaluate the sealing of cavities of dentinal occlusal caries lesions, reproduced in vitro, with flow resin compared to cavity restorations presenting healthy dentin using microhybrid composite resin. Methods: The sample consisted of 27 healthy deciduous molars where cavities of approximately 2 mm in the fossa region were performed and occlusal cleft of each tooth were sealed, impermeabilization was performed and the sample was randomly divided into 2 groups: group I underwent cariogenic challenge and occlusal sealing with resin flow. The teeth of group II were restored with microhybrid composite resin. The teeth were immersed in 5% methylene blue for 8 hours at 37° C and washed until all the dye was removed from the surface. The teeth were sectioned in the mesio-distal direction. The penetration of the dye was evaluated: 0- no penetration; 1- dye penetration up to 1/3 of the restoration; 2- dye penetration up to 2/3 of the restoration depth; 3 - penetration of dye into the pulp wall. The results were analyzed by the Biostat 4.0 program. Descriptive analysis and the mode among the examiners submitted to the Mann-Whitney test. Results: There was no significant difference in microleakage between restoration performed in healthy dentin with microhybrid composite resin or maintenance of infected dentin in primary teeth sealed with resin flow (p = 0.6035). Conclusion: It was concluded that the marginal infiltration of primary molars sealed with microhybrid composite resin and resin flow was not influenced by the removal -or not -of the carious tissue or the material used.
