DenPAR: Annotated Intra-Oral Periapical Radiographs Dataset

This dataset, named "DenPAR: Annotated Intra-Oral Periapical Radiographs Dataset," comprises a collection of intraoral periapical (IOPA) radiographs specifically curated for the detection of alveolar bone loss. The dataset includes the following: IOPA Radiographs: Radiographs images suitable for dental analysis. Alveolar Crestal Bone Level Annotations: Precise markings indicating bone levels for detection and evaluation of bone loss. Keypoint Annotations: Annotations include critical points such as the Cemento-Enamel Junction (CEJ), APEX, and bounding box for each tooth. Teeth Annotations: Data identifying individual teeth in each radiograph. Tooth Segmentation: Segmented regions of each tooth, aiding in targeted analysis. This dataset aims to support research and development in dental imaging, particularly in automated bone loss detection and related dental diagnostic applications.
