Root canal pain relief: simple technique may ease Post-Procedure discomfort
NCT ID NCT07648862
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a technique called apical patency—gently passing a small file just beyond the tooth root during root canal treatment—reduces pain afterward. 150 adults with inflamed but painless teeth (asymptomatic irreversible pulpitis) were randomly assigned to receive root canal treatment with or without this extra step. The main goal was to see how many people felt pain 24 hours later, and how intense it was over the next few days.
