Temporomandibular Disorders and Headache: A Retrospective Analysis of 1198 Patients

Table 5

Absolute frequency and percentage [ (%) values] of DC/TMD diseases in Group with Headache (GwH) and Group without Headache (GwoH); difference in prevalence [ (%) values]; and squared value of correlation between presence of headache and dysfunctional diseases. DD with R: Disk Displacement with Reduction, MOL: Mouth Open limitation, and DD without R: Disk Displacement without Reduction.
