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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether 3D-printed crowns work better than standard stainless-steel crowns for restoring damaged first permanent molars in children. The study will compare how well each crown holds up, its effect on gum health, and how satisfied children and parents are with the result. Forty children with badly decayed or defective molars will receive either a 3D-printed or stainless-steel crown and be followed for 18 months.

What this could mean

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

Active substance
3D-printed crown or prefabricated stainless-steel crown
What this could lead to
If successful, 3D-printed crowns could offer a more comfortable and better-fitting option for children needing tooth restoration.
What could go wrong
This is a small, early-stage trial with only 40 participants, so results may not apply to all children. 3D-printed crowns may not be as durable as stainless-steel crowns.
