The Distal wall of the mesiolingual canals were thinned in the danger zone. Then strip perforations were created randomly in 51 teeth. PA images (3 horizontal angles: 20̊ mesial, orthoradial and 20̊ distal) and CBCT were taken and they were evaluated by two observers. Accuracy, sensitivity and specificity of each method were calculated.
