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 Results may not be published yet.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.

Summary

Researchers in Oman are testing whether a structured education program that combines diabetes and oral health advice can improve blood sugar control and gum health in adults with type 2 diabetes. The trial enrolls 290 adults aged 35 and older who have had type 2 diabetes for at least a year. Half receive six face-to-face education sessions over 12 weeks alongside usual diabetes care, while the other half continue standard care. Researchers track blood sugar, gum health, self-care habits, quality of life, and healthcare costs over 12 months.

What this could mean

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

Active substance
a structured diabetes-oral health education program based on the Health Belief Model
What this could lead to
If it works, this could give diabetes clinics a low-cost way to fold gum care into routine diabetes education, potentially improving blood sugar and mouth health at the same time.
What could go wrong
Education alone may not change long-standing habits or blood sugar enough to matter, and results from Oman may not apply elsewhere. The trial also cannot prove that any mouth improvements directly cause better diabetes control.
