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 This study
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
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 Results may not be published yet.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.

When the status isn't known

Summary

This study compares a single-shade flowable composite resin to a multi-shade composite for filling cavities in back teeth. Thirty adults with at least four cavities will receive both types of fillings and be followed for five years. Researchers will check how well the fillings match tooth color and how long they last.

What this could mean

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

Active substance
dental composite resin (flowable monochromatic and polychromatic)
What this could lead to
If successful, this could simplify cavity treatment by using a single-shade material that blends naturally with teeth, reducing time and cost.
What could go wrong
This is a small, early-stage trial with only 30 participants, so results may not apply to everyone. The materials may not match color as well as expected over time.

An estimate. Start dates often move.

Expected to finish

Apr 2031

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
