You may qualify if:

  • Self report of facial ache or pain in the muscles of mastication, the TMJ, or the region in front of ear or inside the ear
  • Positive clinical diagnosis of TMDs. The TMD diagnosis is classified using axis I of the research diagnostic criteria ( RDC) for TMDs. The RDC diagnosis consists of joint pain at rest ( spontaneous pain) and evoked pain (hyperalgesia) on palpation of the TMJ, TMJ reduction consists of reciprocal clicking or joint noise with mandibular movement examination.
  • For joint pain complaint, subjects will be required to have a self-report of at least 1 month of daily or nearly-daily pain.

You may not qualify if:

  • Subjects with infectious arthritis, crystal induced arthropathies, musculoskeletal disorders, subjects with a primary diagnosis of myofascial pain based on the RDC;
  • Subjects with pain attributable to confirmed migraine or head pain condition other than tension headache;
  • Subjects with acute infection or other significant disease of teeth, ears, eyes, nose or throats; subjects with untreated depressive disorder or not on stable antidepressant medication for more than 6 months;
  • Subjects with dental diseases that required ongoing treatment, which would confound the evaluation of orofacial pain;
