Participants recruitment
Patients were recruited in the order in which they appeared for screening sessions in the Fluminense Federal University dental clinics, thus forming a sample of convenience. Two calibrated dental residents (C.T. and F.C.) recruited the patients. The calibration was performed before the start of the screening sessions and teeth selection. In two consecutive days, the investigators clinically and radiographically evaluated 10 teeth with class I and II lesions. After the evaluation, inter-examiner and intra-examiner agreements were estimated, and a score of at least 85% was required for dentists to be considered calibrated.
