First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This study compares two final rinses inside the tooth after root canal treatment for people with severe tooth pain from irreversible pulpitis. One rinse is a cold saline solution (cryotherapy), the other is a steroid solution (dexamethasone). The goal is to see which better reduces pain in the first days after the procedure. Forty adults with painful lower molars will take part.

What this could lead to
If one method works better, dentists may have a simple, low-cost way to ease pain after root canal treatment.
