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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are testing whether 3D photographs can accurately measure facial asymmetry in adults aged 18 to 40 who have no craniofacial deformities. The study uses stereophotogrammetry to create a 3D image and then calculates an asymmetry index to classify faces as symmetric, slightly asymmetric, or asymmetric. The goal is to develop a tool that helps dentists and surgeons decide whether a patient can be treated with braces or needs corrective jaw surgery.

What this could mean

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

Active substance
stereophotogrammetry (3D imaging)
What this could lead to
If successful, this could provide a reliable tool to help doctors decide whether patients with facial asymmetry need orthodontics or surgery.
What could go wrong
The trial is small and observational, so the index may not apply to everyone. It only measures asymmetry, not treatment outcomes.
