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 Results may not be published yet.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.

Summary

This completed trial tested a new type of CT scan (DE-CBCT) to measure jaw bone density in 26 adults needing dental X-rays. The goal was to see if this scan can give dentists better information for planning dental implants. The study compared the new scan's bone density readings with a standard CT scan.

What this could mean

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

Active substance
Dual-energy cone-beam computed tomography (DE-CBCT) scan
What this could lead to
If successful, this could provide dentists with a more accurate way to measure jaw bone density, improving dental implant success rates.
What could go wrong
This is a small, early-stage study with only 26 participants, so results may not apply to everyone. The new scan is still experimental and may not be better than current methods.

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.

Ages

21 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: 1. Patients who need x-ray imaging for dental treatment planning and/or diagnosis 2. Males or females aged older than 21 3. Can follow instructions to be positioned into the CT scanner 4. Can remain physically immobile during the CT scan acquisition 5. Voluntarily sign and date the informed consent Exclusion Criteria: 1. Pregnancy 2. Patients who are unable to comprehend the risks of the study to provide informed consent 3.
