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 Results may not be published yet.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

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.

Summary

This study tests a modified pinhole surgical technique for treating localized gum recession. It compares using a bi-layer collagen membrane versus a connective tissue graft to cover exposed tooth roots. The trial involves 18 healthy adults with gum recession and will measure changes in gum depth, width, thickness, and patient satisfaction over 6 months.

What this could mean

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

Active substance
Bi-layer collagen membrane or connective tissue graft
What this could lead to
If successful, this could offer a less invasive, equally effective option for covering exposed tooth roots, reducing pain and improving gum appearance.
What could go wrong
This is a very small, early-stage trial with only 18 patients, so results may not apply to everyone. The collagen membrane may not work as well as the standard graft, and long-term outcomes are unknown.
