New guided surgery technique could improve healing after failed root canals

NCT ID NCT07184151

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested whether using 3D-guided microsurgery helps bone heal better after a failed root canal compared to standard surgery. It also compared two different filling materials: a newer bioceramic putty and the standard MTA. Twenty-four adults with persistent infections after root canal treatment were randomly assigned to one of four groups. The researchers measured operating time, bone density changes, and pain levels over time.

What this could mean

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

Active substance

Well root putty (bioceramic putty) and MTA (mineral trioxide aggregate) as retrograde filling materials

What this could lead to

If successful, this could show that guided microsurgery and newer filling materials improve bone healing and reduce pain after failed root canal treatment.

What could go wrong

This is a small, early-stage trial with only 24 participants, so results may not apply to everyone. The outcomes focus on short-term measures like operating time and pain, not long-term success.
