Description

Tran-Lan-Khue Pham and a large team present a 2026 method for testing dental devices that find the tip of a root canal. Getting that length right matters for clean, well-sealed root canal work. Electronic locators are hard to judge because real teeth vary and hide the file tip from view.

The team scanned ten human premolars and printed 100 clear resin copies of them. Two motor systems with built-in locators were tested in two rinsing fluids, under still and moving conditions. A paired microscope setup tracked the file tip with fine precision. Readings agreed closely across modes and fluids. The clear models offer a shared yardstick for clinics, makers, and training.
