Summary

This trial tests whether washing out the jaw joint (arthrocentesis) works as well as Botox injections for treating painful temporomandibular joint (TMJ) disorders. Adults with TMJ pain that hasn't improved with standard care will be randomly assigned to one of the two procedures. Researchers will track pain levels, jaw movement, and side effects over six months to see which approach offers better 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) or botulinum toxin (Botox) injection
What this could lead to
If one treatment proves superior, it could offer a more effective option for managing TMJ pain and improving jaw function.
What could go wrong
This is a relatively small trial, so results may not apply to everyone. Both procedures carry risks like pain, swelling, or temporary muscle weakness.
