Summary

This trial investigates whether using an electronic apex locator to determine the exact stopping point during root canal treatment can reduce pain afterward. Participants with a single-rooted tooth needing a root canal are randomly assigned to one of three groups: two groups use the electronic device to guide treatment, and one group uses standard X-ray methods. Pain levels are measured over the first three days after the procedure.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: electronic apex locator (J Morita Root ZX)
What this could lead to: If successful, this could show that using an electronic apex locator reduces pain after root canal treatment, leading to a more comfortable experience for patients.
What could go wrong: This is a small, early-stage trial with 125 participants, so results may not apply to everyone. Pain is subjective and can vary widely between individuals.
