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.
