Summary

This study tested whether taking a combination of trypsin, bromelain, and rutoside before a root canal helps the numbing shot work better and lowers pain after the procedure. 124 adults with painful tooth inflammation (pulpitis) took the medication or a placebo. The goal was to improve anesthesia success and reduce post-treatment pain using a gentler anti-inflammatory option.
