New hope for kids' damaged teeth: regenerative dental treatments show promise
NCT ID NCT07355686
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two ways to help infected, immature permanent teeth heal and grow in children aged 8-15. The treatments used either the body's own blood clot or a special platelet-rich fibrin to encourage root development and reduce infection. The goal was to see which method works better for front versus back teeth.
