Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study will test a new injectable tooth filling material against a standard one for fixing cavities between baby molars in children aged 3 to 8. Fifty kids will get one of the two fillings, and dentists will check how well they hold up over a year. The goal is to see which filling prevents more decay and stays in place better.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Injectable bioactive composite (Giomer) and Resin-Modified Glass Ionomer (RMGI) dental filling materials
What this could lead to
If successful, this could show that the new injectable filling is more durable and effective for treating cavities in children's baby teeth, potentially improving dental care.
What could go wrong
This is a small, early-stage trial with only 50 children, so results may not apply to everyone. The materials might fail or cause sensitivity, and the study is not yet recruiting.
