Temporomandibular joint dysfunction syndrome

This trial compares two types of knee replacement implants in people aged 75 and older: a standard metal-backed component and a cheaper all-polyethylene (plastic) one. The goal is to see if the all-polyethylene implant performs as well in terms of pain relief, movement, and how l…

This trial tests whether a custom-made plastic implant (ultra-high molecular weight polyethylene) works better than a standard titanium implant for people with chronic jaw dislocation. Participants have a jaw that repeatedly dislocates and has not improved with conservative treat…

This study tests whether adding the drug sodium valproate to a standard jaw-washing procedure can lower inflammation in people with a painful jaw joint condition. Ten female participants with jaw clicking and pain will receive the drug intravenously during the procedure. Research…

This study tests whether wearing a custom mouth splint and getting a granisetron injection into the jaw muscle reduces pain from temporomandibular disorders (TMD) better than the splint alone or with lidocaine. About 48 adults with jaw muscle pain will be followed for 6 months. T…

This study tests a computer-guided needle technique combined with a platelet-rich plasma (PRP) injection for people with a painful jaw joint condition called temporomandibular disorder (TMD). The goal is to see if the computer-guided method improves jaw function and reduces pain …

This study looks at tiny particles called exosomes, taken from a patient's own platelet-rich plasma, to see if they might help repair jaw joints. Researchers will compare these exosomes with other blood products in lab tests on cells. The goal is to understand their content and p…

This study is tracking 120 people who received a HYPE SCS hip stem during total hip replacement. Researchers will monitor how long the implant lasts, how satisfied patients are, and any complications over 5 years. The goal is to confirm the device is safe and works as intended in…

This study is investigating whether bruxism (teeth grinding or clenching) is associated with pelvic pain, erectile dysfunction, and anxiety in young men aged 18-30. Researchers will use questionnaires and physical exams to assess 100 participants. The goal is to better understand…

This study explores whether bruxism (teeth grinding or clenching) is related to pelvic floor dysfunction in young women aged 18-30. Researchers will use questionnaires and physical exams to assess jaw function, pelvic floor symptoms, and anxiety in 100 participants. The goal is t…

This study looks back at the medical records of about 4 million people who had physical or occupational therapy for muscle and joint problems. Researchers want to see if different ways of giving therapy lead to different results. No new treatments are tested—the goal is to learn …
