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.
