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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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 tested two types of tooth-colored fillings for cavities in back teeth: a self-hardening composite that sets without a special light, and a light-activated bioactive composite. Fifty adults received one of the two fillings, and their performance was tracked for two years. The goal was to see if the self-hardening material works as well as the standard light-cured option.

What this could mean

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

Active substance
Self-cured resin composite (Stela, SDI) and light-cured bioactive nano-hybrid resin composite (Beautifill II, Shofu)
What this could lead to
If successful, self-cured composites could offer a simpler, more reliable option for filling cavities in hard-to-reach areas without needing a curing light.
What could go wrong
This is a small, completed trial with only 50 participants. Results may not apply to all patients or tooth types, and long-term durability beyond 2 years is unknown.
