Battle of the bright smiles: which technique best hides MIH white spots?
NCT ID NCT07715370
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This trial tests three different surface treatments—microabrasion, etch-bleach, and macroabrasion—before applying a resin infiltration procedure to improve the appearance of white spots on permanent front teeth in children aged 8 to 14 with molar incisor hypomineralization (MIH). The goal is to find the most effective, conservative approach to reduce these enamel opacities and improve the child's quality of life. Researchers will measure color change and use a questionnaire to assess how the treatment affects the child's well-being.
