What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

Summary

This study compares four different dental filling materials in 20 patients with cavities in their back teeth. The fillings are evaluated over 9 months for how well they hold up, look, and affect tooth health. The goal is to see if newer bioactive materials perform better than standard ones.

What this could mean

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

Active substance
dental filling materials (Tetric N-Ceram Bulk-fill, Stela, Cention Forte, Activa BioActive Restorative)
What this could lead to
If successful, this could help dentists choose better filling materials that last longer and cause fewer problems.
What could go wrong
This is a small, early-stage study with only 20 patients and a short follow-up of 9 months. Results may not apply to everyone or predict long-term performance.
