ABSTRACT

The diagnosis of carious lesions during the initial phase of tooth demineralization allows us to establish preventive and therapeutic measures that can reverse the carious process before the formation of macroscopic lesions.
Objective.To evaluate the in vitro diagnostic capacity of the laser fluorescence technique and that of the International Caries Detection and Assessment System (ICDAS II), and validate the same based on histology.
Materials and methods. The occlusal surfaces of 87 permanent teeth with no restorations or cavities were assessed both visually and using laser fluorescence (LF) and the ICDAS II. Stereomicroscopy was used to evaluate sensitivity and specificity.
Results.The sensitivity of the ICDAS II was 0.91 and specificity 0.61. In the case of LF, sensitivity was 0.95 and specificity 0.68. LF measurements showed a moderate correlation with the histological diagnosis: Spearman Correlation of 0.560. The ICDAS measurements displayed a moderate correlation with the histological diagnosis: Spearman Correlation of 0.568.
Conclusions.ICDAS II and laser fluorescence sensitivity are high and can detect 9 out of 10 teeth with lesions on occlusal surfaces. ICDAS II specificity indicates that for every 10 sound teeth, 4 are considered to have lesions and the specificity of the FL shows that 3 out of 10 sound teeth were recorded as having lesions.
