Effect of Amalgam Restorations and Operation Parameters on Diagnostic Accuracy of Caries Detection Using Cone Beam Computed Tomography: An In Vitro Study

Table 2

The mean sensitivity, specificity, and AUC scores for all three readers combined for approximal caries detection.

Mode	Sensitivity (true positive rate)		Specificity (1—false positive rate)		AUC (area under ROC curve)		95% CI for AUC
