Automatic Measurement of the Root Canal Working Length

Purpose

Measuring a tooth's root canal by hand is slow and unforgiving, and a small error can mean a failed procedure. A dental research team wanted to prove that AI could read an ordinary X-ray and measure the working length on its own, reliably enough to trust in the clinic.

Description

We trained a deep-learning vision model to locate the root canal in periapical X-ray images and calculate its working length automatically, then wrapped it in an interface a clinician could actually use. Captured film is digitized on a small camera rig and cleaned up before the model traces the canal and converts its length into millimeters, saving annotated results per patient. It turned a fiddly manual measurement into a one-click read, exactly the kind of high-stakes computer-vision problem we take on and ship.
