Root canal pain relief may depend on your DNA

NCT ID NCT07012382

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at whether a specific gene variation (SCN9A rs6746030) affects the success of numbing injections for root canal treatment. Researchers compared 200 patients with irreversible pulpitis who either had successful or failed anesthesia. By analyzing DNA from cheek swabs, they aimed to see if certain gene types are linked to poor numbing. The goal is to understand why some people don't get numb and potentially personalize dental pain management.

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 help dentists predict who might not get numb from standard injections, leading to personalized anesthetic plans for root canal patients.

What could go wrong

This is a small, completed observational study, not a treatment trial. The findings may not apply to all patients or change clinical practice directly.
