Occlusal Caries Detection and Diagnosis Using Visual ICDAS Criteria, Laser Fluorescence Measurements and Near- İnfrared Light Transillumination Images

Objective: Current diagnostic tools for non-cavitated occlusal caries are not very reliable. For this reason, newer systems need to be developed. The aim of this study was to compare the performance of visual inspection (ICDAS-II), laser fluorescence (DIAGNOdent pen), and near-infrared transillumination technique (DIAGNOcam) in the detection of non-cavitated occlusal caries lesions under clinical and laboratory conditions in 90 third molar teeth planned for extraction. Materials and methods: Ninety third molar teeth were firstly examined in clinical conditions, scored according to ICDAS II criteria and examined with DIAGNOdent pen and DIAGNOcam devices. After finishing the clinical examination, teeth were reevaluated shortly after the extractions with the same methods. Then, teeth were sectioned for histological validation according to Downer ’s criteria. Sensitivity, specificity, accuracy and area under the receiver operating characteristic curves (AUCs) were calculated based on the histological results. Results: For the D0-D1-4 threshold, the AUC values ranged between 0.754 and 0.881 for all systems. Sensitivity values ranged between 80.5-96.1% and specificity values ranged between 61.5-84.6% for the three caries detection methods. DIAGNOcam had the best correlation value (0.616) according to histological observations and demonstrated a sensitivity rate of 96.1%, a specificity rate of 61.5% and an accuracy rate of 91.1%. Conclu sions: DIAGNOcam was found to be the most ef...
