Keypoint-based detection of periodontal radiographic bone loss on bitewing radiographs using YOLO11-pose: a clinician-AI agreement study
Abstract Background Radiographic assessment of periodontal bone loss on bitewing radiographs is a manual, interpretive task subject to inter- and intra-observer variability. This study aimed to develop and internally validate a YOLO11-pose model for automated localization of the cemento-enamel junction (CEJ) and alveolar bone crest (ABC) and to assess the agreement of its CEJ-ABC distance measurements with a multi-expert consensus reference. Methods A total of 927 bitewing radiographs (6,276 interproximal sites) fr …
