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 This study
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.

This status has not been confirmed recently, so it may be out of date.

Summary

This trial compares two surgical techniques for treating receding gums, a condition where the gum tissue pulls away from the teeth, exposing the roots. One technique is the standard coronally advanced flap, and the other is a newer vertical variation. Both are performed along with a connective tissue graft and a special enamel protein to encourage healing. The study will measure how much root coverage each technique achieves and how the gums look afterward, using 3D scans to track changes over six months.

What this could mean

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

Active substance
Two surgical procedures: Vertically Coronally Advanced Flap (VCAF) and Coronally Advanced Flap (CAF), both combined with a connective tissue graft and enamel matrix derivative.
What this could lead to
If VCAF proves superior, it could offer a more effective surgical option for covering exposed tooth roots, improving both gum health and smile aesthetics.
What could go wrong
This is a small, early-stage trial with only 16 participants, so results may not apply broadly. As with any surgery, risks include infection, swelling, and incomplete root coverage.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

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.
