Migraine with aura and dental occlusion: a case report.

Migraine is defined as a primary headache; however, some reports may suggest a relationship with dental occlusion and dental parafunction (clenching or grinding of the teeth). A patient diagnosed with migraine with aura, with concomitant temporomandibular joint and masseter muscle pain, was treated by the use of a dental appliance. The treatment succeeded in eliminating headache and visual aura, and significantly reducing the other symptoms. A headache related to dental occlusion and dental parafunctions seems to be able to mimic a primary migraine headache. Therefore, dental evaluation is always advised for headache diagnosis.
