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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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

Summary

This study tested a new high-frequency ultrasound probe to measure the depth of gum pockets, a key sign of periodontal disease. Researchers compared the ultrasound measurements to standard manual probing in 39 adults. The goal was to see if the ultrasound could accurately detect early gum disease, potentially offering a more comfortable and efficient diagnostic tool.

What this could mean

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

Active substance
High-frequency intraoral ultrasound probe
What this could lead to
If successful, this could provide a faster, less painful way to diagnose gum disease early, potentially improving treatment outcomes.
What could go wrong
This is a small, early-stage study with only 39 participants. The ultrasound method may not be as accurate as manual probing in all cases, and more research is needed.
