Summary

This study will compare three methods for testing whether a tooth's nerve is alive (vital) or dead (nonvital): laser Doppler flowmetry, cold testing, and electric pulp testing. About 150 people who need root canal treatment will receive all three tests before treatment. The goal is to see which test is most accurate at diagnosing tooth vitality.

What this could mean

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

What this could lead to: If successful, this could lead to more accurate and reliable methods for dentists to determine if a tooth is alive or dead, improving treatment decisions.
What could go wrong: This is an early diagnostic study, not a treatment trial. The new laser method may not prove more accurate than existing tests, and results may not apply to all dental situations.
