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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at how a procedure called temporomandibular joint arthrocentesis—a washout of the jaw joint—affects the masseter muscle, a key chewing muscle. Researchers will use ultrasound and strain elastography to measure the muscle's thickness and elasticity before and after the procedure in adults aged 18 to 40 with jaw joint dysfunction. The goal is to see if the procedure leads to measurable changes in the muscle, which could help refine treatments for jaw joint problems.

What this could mean

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

Active substance
Temporomandibular joint arthrocentesis (a procedure to wash out the jaw joint)
What this could lead to
If successful, this could improve understanding of how jaw joint washing affects nearby chewing muscles, potentially guiding better treatment for jaw joint disorders.
What could go wrong
This is an observational study with a small number of participants, so results may not apply broadly. The procedure itself carries standard risks like pain, swelling, or infection.
