Accuracy of the Light-induced Fluorescent Intraoral Camera in Occlusal Caries Detection

AIM AND OBJECTIVEThis study was conducted to evaluate the accuracy of a light-induced fluorescence intraoral camera vs the visual-tactile assessment method according to the modified International caries detection and assessment system-II (ICDAS-II) criteria clinically in the detection of initial occlusal caries. MATERIALS AND METHODSOcclusal surfaces of 260 molar and premolar teeth from 52 adult participants were examined by two calibrated observers, using two diagnostic methods. Teeth were initially assessed visually according to the criteria of the ICDAS-II, and then by fluorescence camera (Soprolife®). Inter- and intraobserver agreements were measured using Cohen's kappa test. Correlation between methods was calculated using Wilcoxon signed-rank test, and effect size for comparison between the two modalities. The sensitivity, specificity, predictive values, diagnostic accuracy, likelihood ratios (LRs), area under the receiver operating characteristic (ROC) curve (AUC), and 95% confidence interval (95% CI) of the AUC for caries detection by Soprolife® were evaluated. RESULTSA significant positive correlation was found between the ICDAS-II and camera measurements (p-value
