ClinConnect Summary

This clinical trial is studying orofacial pain, particularly a type called trigeminal neuralgia, to understand how the way teeth come together (occlusion) may relate to this pain. Researchers want to find out if adjusting how the teeth fit together can help relieve this kind of pain, which can be very uncomfortable and difficult to treat with regular medications or surgeries.

To participate in this study, you must be experiencing orofacial pain that has not improved with treatments like medication or dental procedures. You should meet certain criteria, such as having intense, brief, electric shock-like pain focused in your face or ongoing dull pain that lasts more than two hours each day for over three months. The study is open to both men and women aged 65 and older. If you join the study, you can expect to undergo evaluations related to your pain and possibly receive an occlusal adjustment to see if it helps alleviate your symptoms. Remember, this trial is specifically looking for participants who have not found relief through other means, so it may offer new hope for managing your pain.

• • severe intensity.
• • electric shock-like, shooting, stabbing or sharp in quality.
• • precipitated by innocuous stimuli to the affected side of the face.
• • No clinically evident neurological deficit
• • Not better accounted for by another the International Classification of Headache Disorders 3rd edition diagnosis.
