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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 a small piece of connective tissue from the roof of the mouth to a standard gum-saving surgery helps repair deep bone defects caused by gum disease. Thirty adults with two or more deep gum pockets will receive the surgery on both defects, but only one defect will get the extra tissue graft. Researchers will measure changes in gum attachment, pocket depth, and bone fill after 6 and 12 months to see if the graft makes a difference.

What this could mean

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

Active substance
a surgical procedure called Entire Papilla Preservation Technique (EPPT) with or without a subepithelial connective tissue graft (SCTG)
What this could lead to
If adding a connective tissue graft improves healing, it could lead to a more effective surgical approach for treating deep gum defects and potentially saving teeth that might otherwise be lost.
What could go wrong
This is a small, early-stage trial with only 30 participants, so results may not apply to everyone. The added graft could increase surgical time, cost, or risk of complications without clear benefit.

Study facts

What this study's own registry entry says, in plain language.

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 30 people

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

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Nov 2027

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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥ 18 years, * Good compliance and good oral hygiene * Systemically healthy * Isolated two intrabony defects of more than 3 mm depth, combined with more than 6 mm probing depth and attachment loss (stage III/IV periodontitis) and an intrabony radiographic defect depth (DD) ≥ 3 mm, as evaluated on a digital periapical radiograph * The associated tooth should either maintain normal pulp vitality or should have undergone root canal therapy for at least 6 months before. Exclusion Criteria: * Full-mouth plaque score ≥ 20% (O'Leary et al 1972) * Full-mouth bleeding score ≥ 20% (Cortellini et al 1995) * Smoking * Systemic diseases that would adversely influence wound healing * Medications interfering with post-operative wound healing * Pregnant and lactating females * Previous periodontal surgery in the examined area * III-degree mobility * Furcation involvement * Pulpal pathology or inadequate endodontic treatment
