Controlled Clinical Trial
A mandibular advancement appliance reduces pain and rhythmic masticatory muscle activity in patients with morning headache.
To evaluate the influence of an oral appliance on morning headache and orofacial pain in subjects without reported sleep-disordered breathing (SDB). ⋯ Short-term use of an MAA is associated with a significant reduction in morning headache and orofacial pain intensity. Part of this reduction may be linked to the concomitant reduction in RMMA.

To use magnetic resonance imaging (MRI) and voxel-based morphometry (VBM) to search for evidence of altered brain morphology in patients with temporomandibular disorders (TMD). ⋯ These data support previous findings by showing that TMD, like other chronic pain states, is associated with changes in brain morphology in brain regions known to be part of the central pain system.

To determine in a representative sample of the Australian adult population the relationship between age, gender, and two components of perceived stress (distress and control) and to investigate whether the relationship of perceived stress and temporomandibular disorder (TMD)-related orofacial pain symptoms was modified by gender or age. ⋯ The higher prevalence of TMD-related orofacial pain symptoms in females was better explained by their lower perception of control than from a greater perception of distress.
-
To establish a quantitative sensory testing (QST) profile in the trigeminal (V) area and test for site and gender differences in healthy humans. ⋯ Application of this standardized QST protocol may allow for a better understanding of the underlying mechanisms from somatosensory phenotypes and provide basic information for the study of sensory dysfunctions in the V area.

Multicenter Study
Influence of cross-sectional temporomandibular joint tomography on diagnosis and management decisions of patients with temporomandibular joint disorders.
To assess whether changes in diagnoses and management of temporomandibular joint disorder (TMJD) patients are influenced by radiographic findings and if there is an association between specific radiologic alterations and management strategy changes. ⋯ Radiographic degenerative findings increased the chance of changes in management strategy. However, 73% of the TMJD patients had no changes in management after radiographic examination. In cases with changes, these were mainly adjustments within management categories.
