Dental filling showdown: which material holds up best?
NCT ID NCT06212141
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two types of tooth-colored filling materials for cavities between teeth. 54 healthy adults aged 18-60 received fillings using either a standard bulk-fill composite or a newer thermoviscous material. Researchers will check the fillings at 6 and 12 months for how well they stay in place, resist staining, and prevent new decay.
