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 Results may not be published yet.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.

Summary

This trial evaluates a modified surgical technique called the vertically coronally advanced flap (V-CAF) combined with a connective tissue graft and tissue regeneration materials to treat gum recession. It focuses on people with Miller Class III recession, a more severe form where the gum has pulled back significantly. Researchers will also examine whether a pre-operative difficulty score can predict how much root coverage is achieved. Participants will be followed for 12 months to assess healing and tissue stability.

What this could mean

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

Active substance
Vertically coronally advanced flap (V-CAF) surgical procedure combined with connective tissue graft and tissue regeneration materials
What this could lead to
If successful, this could offer a more effective surgical option for treating severe gum recession and help dentists predict which patients will benefit most.
What could go wrong
This is a small, early-stage study, so results may not apply to everyone. Surgery carries risks like infection, swelling, or incomplete root coverage.
