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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Peri-implantitis is an infection around a dental implant that can damage the surrounding bone. Researchers are comparing four non-surgical cleaning methods, including mechanical debridement with titanium curettes, in 70 implants, 56 with peri-implantitis and 14 healthy controls. They will measure clinical signs of healing and use a sensitive lab technique to track titanium and other metal particles released into the fluid around the implants. The goal is to see which cleaning approach controls infection while releasing the fewest metal particles.

What this could mean

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

Active substance
Mechanical debridement with titanium curettes
What this could lead to
If one cleaning method releases fewer metal particles while still reducing infection, dentists could choose it to protect both the implant and the surrounding bone.
What could go wrong
This is a small, short study of 70 implants followed for six weeks. It can show which method releases fewer particles, but it cannot prove long-term implant survival or rule out other sources of metal in the mouth.

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 70 people

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

Expected to start

Oct 2026

An estimate. Start dates often move.

Expected to finish

Jun 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.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

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

Inclusion Criteria: * Being systemically healthy and older than 18 years of age. * Having implants diagnosed with peri-implantitis according to the 2017 World Workshop criteria (probing depth ≥ 5 mm, bleeding on probing positive, radiographic bone loss \> 2 mm). * Dental implants being in function in the oral cavity for at least 1 year. Exclusion Criteria: * Having received systemic antibiotic therapy within the past 3 months. * Having previously received peri-implantitis treatment at the relevant implant site. * Being pregnant or lactating.
