Laser light may help save infected young teeth and speed root growth
NCT ID NCT07704463
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This trial tests whether using a low-power laser during a pulpotomy (removing infected pulp from a tooth) can improve healing and root formation in children aged 6 to 14 with painful, irreversible pulpitis in immature permanent molars. Participants receive either laser treatment plus a standard capping material (MTA), laser at a different wavelength plus MTA, or MTA alone. The study tracks pain, dentin bridge formation, and overall success over 12 months.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- laser therapy (660 nm and 970 nm diode lasers) combined with mineral trioxide aggregate (MTA) capping material
- What this could lead to
- If successful, this approach could offer a faster, less painful treatment for saving infected young permanent teeth and promoting natural root development.
- What could go wrong
- This is a small, early-stage trial with only 57 participants, so results may not apply to all cases. Laser effects on pain and healing are still uncertain, and long-term success beyond 12 months is unknown.
