First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether adding a surface sealant to a bulk fill dental filling helps it last longer and resist staining. 53 patients received three different fillings each, with or without a sealant. The fillings were checked every 6 months for 5 years to see if they failed, changed color, or caused problems.
