Can light or laser disinfection boost dental implant success in infected sockets?
NCT ID NCT07753044
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This trial tests whether photoactivated disinfection (using a light-activated dye) or Er,Cr:YSGG laser disinfection can better clean infected tooth sockets before placing an immediate dental implant, compared to standard chlorhexidine rinsing. The goal is to see which method leads to better implant stability and bone healing. Adults with a posterior tooth needing extraction and showing signs of infection may participate. The study measures implant stability, bone density changes, and pain or swelling after the procedure.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Photoactivated disinfection (toluidine blue plus light), Er,Cr:YSGG laser disinfection, or chlorhexidine irrigation, each followed by immediate implant placement
- What this could lead to
- If successful, this could identify a better way to disinfect infected tooth sockets before immediate implant placement, potentially improving implant stability and bone healing.
- What could go wrong
- This is a small early-stage trial with only 9 participants, so results may not apply broadly. The disinfection methods may not significantly outperform chlorhexidine, and there are risks of post-operative pain, swelling, or implant failure.
