Laser zaps cavity bugs better than drill?
NCT ID NCT07493278
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two ways to remove cavities in children: using a laser or a traditional drill. Researchers measured how much cavity-causing bacteria (Streptococcus mutans and Lactobacillus) remained in the tooth after each method. The goal was to see if the laser could be a less invasive alternative to drilling. The study involved 32 children and used PCR testing to check bacteria levels before and after treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Er,Cr:YSGG laser
What this could lead to
If successful, this could show that laser treatment is as good as or better than drilling for reducing cavity-causing bacteria, potentially leading to less painful dental procedures.
What could go wrong
This is a small, completed study with only 32 participants, so results may not apply to all children or cavities. The study measured bacteria levels, not long-term cavity prevention or tooth health.
