NCT ID NCT06934603
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This observational study tracks 150 orthodontic patients to measure microplastic particles in their saliva and urine before and during clear aligner treatment. Researchers want to see if wearing clear aligners increases microplastic exposure over time. The study does not test any treatment or intervention—it simply observes and measures.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this study could reveal whether clear aligners release microplastics into the body, informing future safety guidelines.
What could go wrong
This is an early observational study, not a treatment trial. It only measures exposure, not health effects, and results may not apply to all aligner brands or users.
