First seen Apr 07, 2026 · Last updated May 09, 2026 · Updated 5 times

Summary

This study tested whether injecting one of three drugs (dexamethasone, diclofenac sodium, or chymotrypsin) into the ligament around a tooth before the usual numbing shot helps reduce pain during root canal treatment for severe toothaches. 105 adult men with an infected lower molar took part. The goal was to see if these drugs could make the numbing more effective and reduce the need for extra shots.
