Root canal relief? study tests best way to clean teeth
NCT ID NCT07241650
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at different ways to clean a tooth during a root canal to see which causes the least pain and improves quality of life. 90 adults with a specific type of tooth infection will be randomly assigned to one of three irrigation methods. They will report their pain levels at several time points over a week and complete a quality-of-life questionnaire.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Sodium hypochlorite (bleach) and HEDP (a chelating agent) used as irrigation solutions during root canal treatment
- What this could lead to
- If successful, this could identify a better way to clean root canals, leading to less pain and faster recovery after treatment.
- What could go wrong
- This is a small, early-stage study (90 people) comparing different techniques, so results may not apply to all patients or root canal cases. Pain is subjective and varies widely.

Subjects with missing opposing or adjacent teeth5. Pregnant or breastfeeding female subjects6. Teeth requiring additional anesthesia methods (e.g., intrapulpal, intraligamentary, second block anesthesia, or additional local anesthetic agent) will be excluded from the study if anesthesia is insufficient.7. Teeth with apical lesions will not be included in the study.8. Teeth with root resorption will not be included in the study.9.
