“…For example, bitewing radiographs are the method of choice for caries detection [ 6 , 9 , 10 , 11 , 12 , 13 ], periapical and panoramic radiographs for detecting and classifying periapical lesions or PBL [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. In contrast, little is known about the inter- and intra-rater reliability for detecting caries [ 28 ] and periapical lesions [ 14 , 15 , 16 ] on periapical radiographs which are also among the routines in daily dental practice on this image type. In addition, there is limited data available on how reliable dentists detect PBL and endo-perio lesions on periapical radiographs.…”
