Which filling base lasts longest? a Head-to-Head test
NCT ID NCT07762651
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This trial tests five different materials placed beneath composite fillings in back teeth to see which one best supports the filling and keeps it firmly attached. Adults needing a standard back-tooth filling will receive one of the five materials at random. Dentists will check the fillings over 18 months to see how well each material holds up, aiming to find the most reliable option for everyday dental care.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- dentin replacement materials (Biodentine, ACTIVA BioACTIVE, glass ionomer cement)
- What this could lead to
- If one material proves superior, it could lead to longer-lasting, more durable tooth fillings for cavities, reducing the need for re-treatment.
- What could go wrong
- This is a small, early-stage trial, so results may not apply to all patients. The materials could perform differently in real-world conditions, and long-term outcomes beyond 18 months are unknown.
