Online published on 4 June, 2019. Abstract Dental caries is one of the most significant problems worldwide. Occlusal caries constitutes more than 90% of caries in children. Molars and premolars are considered as the most vulnerable teeth of carious attacks which is related to the morphology of their occlusal surfaces along with the difficulty of plaque removal. The aim of this study was to evaluate the clinical performance of an impedance spectroscopy technology (Carie Scan pro device) and laser fluorescent (DIAGNOdent pen) for detecting non-cavitatedocclusal carious lesions in the first permanent molar teeth. A total of 139 first permanent molar teeth pooled from 50 children with age rangof 8–9 years wereexamined. The selection criteriawere teeth (first permanent molars) with carious lesions ranging from 0 to 3 according to ICDASII (gold standard) criteria then the clinical sensitivity, specificity and area under the receiver-operator curves of DIAGNOdent and Carie Scan pro were examined. Repeatability was also analyzed using intra-classcorrelation coefficient (ICC).
