Summary

This study looked at 88 healthy adults with infected teeth to see if different irrigation methods during root canal treatment affect pain afterward. Participants had a tooth with a chronic infection and received one of several irrigation techniques. The goal was to find which method causes the least pain after the procedure.

What this could mean

What this could lead to
If successful, this could help dentists choose a less painful irrigation method for root canals.
What could go wrong
This is a small, completed study with 88 participants, so results may not apply to all patients or tooth types.
