Which painkiller works best after a root canal? study pits diclofenac against ibuprofen
NCT ID NCT07565012
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared two common painkillers—diclofenac sodium and ibuprofen—for managing pain after a root canal. Sixty adults with irreversible pulpitis received one of the two drugs right after treatment, and their pain was tracked for 48 hours. The goal was to see which drug provides better relief and reduces the need for extra pain medication.
