New injection could ease jaw pain better than standard treatment
NCT ID NCT07075276
First seen Jun 27, 2026 · Last updated Aug 18, 2026 · Updated 2 times
Summary
This study compares a new injection of liquid phase concentrated growth factor (LPCGF) to standard arthrocentesis (joint washing) for people with painful jaw clicking and limited mouth opening due to a displaced disc. Thirty-two adults aged 18-45 with unilateral disc displacement will be randomly assigned to one of the two procedures. The goal is to see if LPCGF reduces pain and improves mouth opening more than the conventional treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Liquid Phase Concentrated Growth Factor (LPCGF)
- What this could lead to
- If it works, this could offer a more effective, less invasive option for treating painful jaw clicking and limited mouth opening.
- What could go wrong
- This is a small, early-stage trial with only 32 participants, so results may not apply to everyone. The treatment is compared to a standard procedure, and benefits may be modest.
