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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study looked at 200 healthy people to see if the growth stage of upper wisdom teeth (third molars) on X-rays matches the maturity of the midpalatal suture—a bone seam in the roof of the mouth that guides orthodontic treatment. Researchers used cone beam CT scans and X-rays to compare these two measures. If a strong link exists, dentists could use routine X-rays instead of extra CT scans to plan treatments like palate expansion.

What this could mean

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

What this could lead to
If a reliable link is found, dentists might use routine X-rays to decide on palate treatments without extra scans.
What could go wrong
This is a small, completed observational study—not a treatment trial. The correlation may be weak or not useful in practice.
