AI-Based Working Length Determination in Curved Root Canals

This study tests whether artificial intelligence (AI) can accurately measure the length of curved root canals from dental x-rays. Curved root canals are hard to measure correctly, and wrong measurements can lower the success of root canal treatment. Adults over 18 years old who need root canal treatment can take part. Researchers will use x-rays taken during the patient's normal treatment. No extra x-rays, procedures, or visits are needed. An AI program will be trained to measure canal length automatically, and its measurements will be compared to measurements made by a human expert. The results may show whether AI can measure root canal length faster and more consistently, which could help dentists plan treatment more accurately in the future.

Inclusion Criteria: * Eligibility Criteria * Age 18 years or older * Presenting for routine root canal treatment at Alanya Alaaddin Keykubat University Faculty of Dentistry * Radiographically identified curved root canal(s) * Periapical radiograph obtained using the paralleling technique during working length confirmation * Willing and able to provide informed consent Exclusion Criteria: * Age under 18 years * Root canals without curvature * Periapical radiographs of insufficient diagnostic quality (e.g., distortion, poor image quality preventing accurate canal length assessment) * Unwillingness to provide informed consent
