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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether adults with bruxism—teeth grinding or clenching—have different blood levels of vitamin D, calcium, and related hormones compared to those without the condition. Researchers will compare these biochemical markers between the two groups using existing lab results. The goal is to see if these factors might be linked to bruxism, offering clues for future research.

What this could mean

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

What this could lead to
If a link is found, it could point toward new ways to understand or manage bruxism through metabolic or nutritional approaches.
What could go wrong
This is a small observational study, so it cannot prove cause and effect. Results may not apply to everyone with bruxism.

Who is studied

The study population consisted of adults evaluated at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Ankara Yildirim Beyazit University. Eligible participants with suspected bruxism were assessed using self-reported bruxism behaviors and standardized clinical examination findings. Participants meeting the predefined criteria for bruxism constituted the bruxism group. Eligible participants without bruxism were selected as controls and matched to the bruxism group according to age and sex. Biochemical laboratory results available from the preceding 6 months were evaluated.
