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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 study tests an artificial intelligence system that measures the width of keratinized gingiva (a type of gum tissue) from smartphone photos. Researchers will compare the AI's measurements to those made by dental experts to see how accurate the tool is. The goal is to make gum disease diagnosis more consistent and less dependent on the examiner.

What this could mean

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

Active substance
Artificial Intelligence-Based Keratinized Gingiva Width Assessment
What this could lead to
If successful, this AI tool could make gum disease diagnosis faster, more consistent, and accessible using just a smartphone photo.
What could go wrong
This is a small, early-stage study. The AI may not perform as well in real-world settings or on different populations, and it is not a treatment.
