Summary

This study tested two techniques for washing out the jaw joint (arthrocentesis) in 30 adults with TMJ disorders. One method used a single needle, the other a catheter. Researchers measured pain and how wide patients could open their mouths. The goal was to see which approach provides better symptom relief.

What this could mean

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

Active substance
Arthrocentesis (joint washing procedure)
What this could lead to
If one method proves better, it could offer a simpler or more effective way to ease TMJ pain and improve jaw movement.
What could go wrong
This is a small, completed study with only 30 participants, so results may not apply to everyone. The procedure itself carries minor risks like infection or discomfort.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Patients included in this study were adult individuals aged 18 years and older who were diagnosed with stage 3 or higher temporomandibular joint (TMJ) disorder according to the Wilkes classification, based on magnetic resonance imaging (MRI) in addition to clinical evaluation. Eligible patients had unilateral internal TMJ disorder and exhibited clinical symptoms such as TMJ-related pain and/or joint sounds, and limited mouth opening. Furthermore, only patients whose symptoms persisted despite at least one month of occlusal splint therapy were included. Exclusion criteria were as follows: patients diagnosed with myofascial pain or muscle-related functional limitation; those who had previously undergone intra-articular injection or other invasive procedures involving the TMJ; patients with connective tissue diseases such as rheumatoid arthritis or with neurological disorders; patients with a history of major jaw trauma; and individuals with psychiatric disorders or a history of substance abuse.
