Ratings on the VAS showed moderate anxiety (55.74±17.46). Testing the validity of the MDAS versus the VAS by ROC curve (Figures 1 & 2) revealed a considerable and significant area under the curve (AUC) both for dental anxiety (AUC=0.871, 95% confidence interval [CI]:0.837-0.904) and dental phobia (AUC=0.852, 95% CI: 0.820-0.885). The best cutoff for dental anxiety on the MDAS scale as indicated by the ROC curve was >15, with sensitivity and specificity of 0.796. In contrast, the best cutoff for dental phobia was >16 (with sensitivity of 0.953 and specificity of 0.691).
