New fluoride resin may stop tooth stains from clear aligners
NCT ID NCT07426432
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using a fluoride-releasing composite resin for aligner attachments can prevent white spot lesions (early cavities) during clear aligner therapy. Twenty-four people aged 16-24 with mild crowding will have one side of their mouth get the fluoride resin and the other side a standard resin. Researchers will check for white spots at 3 and 6 months using a laser device.
