Toothache breakthrough: blood test may predict need for root canal
NCT ID NCT07452614
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether substances in the blood from a decayed tooth can predict if a tooth-saving procedure called vital pulp treatment will succeed. Researchers will collect a small blood sample from the tooth during treatment and check for specific metabolic markers. They will follow 60 patients for 12 months to see if the markers can tell which teeth heal well and which need more intensive treatment like a root canal.

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 a simple blood test that helps dentists decide the best treatment for a painful tooth, avoiding unnecessary root canals.
- What could go wrong
- This is a small, early-stage study with only 60 participants. The biomarkers may not reliably predict outcomes, and results may not apply to all patients.
