Summary
This study tests whether using an 810 nm diode laser during root canal retreatment helps the bone around the tooth heal better. Forty adults with a failed root canal and a visible infection will receive standard retreatment plus either laser disinfection or a calcium hydroxide paste. Healing will be checked with 3D X-rays after one year.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
810 nm diode laser
What this could lead to
If it works, this could offer a better way to disinfect root canals during retreatment, potentially improving healing and reducing the need for surgery.
What could go wrong
This is a small, early-stage trial with only 40 participants. The laser is used as an add-on to standard care, so any benefit may be modest. Results may not apply to all tooth types or infections.
