Summary

This study compared pain after root canal treatment using two different filling methods: the single cone cold lateral condensation technique and the continuous wave compaction technique. Sixty adults with irreversible pulpitis (tooth nerve inflammation) were randomly assigned to one of the two methods. Pain was measured before and after the procedure using a standard pain scale. The goal was to see if one technique leads to less discomfort.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
root canal filling technique (single cone cold lateral condensation vs continuous wave compaction)
What this could lead to
If one technique clearly causes less pain, dentists may adopt it to make root canals more comfortable.
What could go wrong
This is a small, single-center study with only 60 participants. Results may not apply to all patients or dentists.
