AI reads dental x-rays to grade root canal quality
NCT ID NCT07684482
First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time
Summary
This study tests an artificial intelligence system that automatically evaluates the quality of root canal fillings using dental X-rays. The AI analyzes features like filling length, uniformity, and shape, then classifies the treatment as acceptable or needing improvement. Researchers will compare the AI's results with assessments from experienced dental specialists to see if the technology can provide a reliable, consistent evaluation method.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- deep learning model
- What this could lead to
- If successful, this AI tool could help dentists quickly and consistently assess root canal quality, potentially improving treatment outcomes and reducing the need for repeat procedures.
- What could go wrong
- This is an early-stage study using existing X-rays, not a real-world test. The AI may not perform as well in different clinics or with varied image quality.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Periapical radiographs of teeth with completed root canal treatment from patients Aged between 18 and 60 years will be included, provided they exhibit satisfactory image quality characterized by adequate sharpness, contrast, and minimal noise, allowing clear visualization of the root canal filling and apical region. The radiographs must enable accurate assessment of obturation quality, including filling length, homogeneity, and taper. Both single-rooted and multi-rooted teeth will be considered to ensure adequate anatomical representation. Radiographs with poor image quality, significant distortion, metallic artifacts, post-core restorations, root resorption, fractures, or incomplete visualization of the apex will be excluded to ensure reliable analysis.
