NCT ID NCT07319884
First seen Jan 11, 2026 · Last updated Jun 14, 2026 · Updated 21 times
Summary
This study tests whether applying fluoride varnish to teeth can prevent white spot lesions (early cavities) that sometimes appear during clear aligner therapy. Twenty-five people aged 16-24 with mild crowding will have one side of their mouth treated with fluoride varnish and the other side left untreated for comparison. After six months, researchers will measure any white spots and gum health to see if the varnish helps.
