Eligibility
Inclusion criteria
Inclusion criteria: Task 1 & 3: 1. Images must be clear and free of artifacts that severely impact diagnosis and algorithm performance. 2. The scan range must completely encompass the target tooth/teeth, extending from the crown to at least 3mm beyond the root apex to ensure the entire root and apical foramen are included. 3. The field of view must cover three teeth. 4. Target areas must include anterior teeth, premolars, and molars. Task 2: 1. Images must be clear and free of artifacts that severely impact diagnosis. 2. The scan range must completely include the crown and cervical region of the target tooth and at least one adjacent tooth (except in free-end situations). 3. Target areas must include anterior teeth, premolars, and molars. 4. For proximal caries (mesial and distal), bitewing radiographs or images acquired using the parallel technique are required for caries classification. Task 4: This task will utilize previously collected extracted teeth and does not require patient involvement.
Exclusion criteria
Exclusion criteria: Task 1: 1. Root canal retreatment cases with root canal filling material extruding beyond the apical foramen. 2. Severe artifacts that obscure or prevent identification of key measurement landmarks (e.g., pulp chamber walls, root canal walls, apical foramen). 3. Conditions preventing clinical root canal length measurement, such as a large apical foramen, external root resorption, root fracture, lateral perforation, or root crack. 4. Severe coronal destruction where normal anatomical contours cannot be defined, preventing determination of a coronal reference point. 5. Excessive scanning slice thickness that cannot meet the precision requirements for fine measurements. Task 2: 1. Severe artifacts that prevent clear delineation of enamel, dentin, carious areas, restoration margins, or pulp chamber boundaries. 2. Extensive coronal defects that preclude effective assessment of caries extent. 3. Excessive scanning slice thickness that cannot meet the diagnostic requirements for detecting minute carious lesions. Task 3: 1. Artifacts or scanning parameters (e.g., slice thickness) that cannot meet the precision requirements for fine measurements. Task 4: This task will utilize previously collected extracted teeth and does not require patient involvement.
