Craniomandibular disorders in patients with different types of headache

One hundred recurrent headache patients, referred for neurologic examination, were randomly invited for a functional examination of their stomatognathic system. The patients were grouped on the basis of headache localization, neurologic diagnosis of the headache, and stomatognathic diagnosis. The relationship between groups was analyzed. Several significant correlations were found between the clinical findings and the localization of headache (P less than 0.05 to P less than 0.001). Patients with or without a definite craniomandibular disorder pain displayed differences in mouth opening capacity (P less than 0.001). The results indicate a close relationship between recurrent headache and craniomandibular disorders, independent of the neurologic diagnosis of the headache.
