Myofascial pain with or without mouth opening limitation was the commonest diagnosis in TMD patient population s , and disc displacement with reduction was the commonest diagnosis in community sample
Headache and Temporomandibular Disorders: Evidence for Diagnostic and Behavioural Overlap
To assess the diagnostic and behavioural overlap of headache patients with temporom and ibular disorders ( TMD ) , individuals recruited from the general population with self-described headaches were compared with non-headache controls . The examination and diagnostic procedures in the Research Diagnostic Criteria ( RDC ) for TMD were applied to both sets of subjects by a blinded examiner . Following their examination , subjects used experience sampling methods to obtain data on pain , tooth contact , masticatory muscle tension , emotional states and stress . Results showed that a significantly higher proportion of the headache patients received an RDC/TMD diagnosis of myofascial pain than non-headache controls . Headache patients also reported significantly more frequent and intense tooth contact , more masticatory muscle tension , more stress and more pain in the face/head and other parts of the body than non-headache controls . These results are similar to those reported for TMD patients and they suggest that headache patients and TMD patients overlap considerably in diagnosis and oral parafunctional behaviours
