Summary

This study tested whether a near-infrared LED device can reduce pain, speed up tooth movement, and lower the risk of root damage in people wearing braces. Sixteen Vietnamese patients aged 11 to 30 received either the real LED device or a sham device during their orthodontic treatment. Researchers measured pain levels, tooth movement, and a biomarker for root damage over several months.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: LED device emitting near-infrared light at 850nm wavelength
What this could lead to: If it works, this could offer a drug-free way to ease pain and reduce root damage during braces treatment.
What could go wrong: This is a very small, early study with only 16 people, so results may not apply to everyone. The device may not work better than a placebo.
