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 This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests whether adding injectable platelet-rich fibrin (i-PRF) or hyaluronic acid gel to standard free gingival graft surgery improves healing and reduces graft shrinkage. Adults with gum recession and insufficient keratinized tissue will be randomly assigned to one of three groups: standard surgery, surgery with i-PRF, or surgery with hyaluronic acid. Researchers will measure graft shrinkage and wound healing over a 3-month follow-up to compare the approaches.

What this could mean

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

Active substance
Injectable platelet-rich fibrin (i-PRF) and hyaluronic acid gel, each added to free gingival graft surgery
What this could lead to
If it works, adding i-PRF or hyaluronic acid to gum graft surgery could improve healing and reduce graft shrinkage, leading to better long-term outcomes for patients with gum recession.
What could go wrong
This is a small, early-stage trial with 45 participants, so results may not apply broadly. The added treatments may not significantly improve healing or shrinkage compared to standard surgery alone.

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

About 45 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start
