To compare patients with combined tension-type headache and myofascial temporomandibular disorder (TMD) with control subjects on two measures of central processing-ie, temporal summation and aftersensations to heat stimulation in the trigeminal nerve and spinal nerve territories. ⋯ The results from this pilot study suggest that aftersensations to painful heat stimulation can appear without temporal summation. Furthermore, the developed test protocol has a good predictive value and may have the potential to discriminate between tension-type headache/TMD patients and control subjects.
-
To test whether patients with temporomandibular disorder (TMD) pain differ from subjects from the general population with regard to their stress-related coping styles. ⋯ Differences in the applied stress-related coping styles of TMD patients and subjects without TMD may have implications for clinical decision making and choosing among treatment alternatives.
-
To use a range of evaluation instruments to assess the content and quality of websites about temporomandibular disorders (TMD) and thereby provide guidance regarding the actual accuracy and comprehensiveness of the information of the sites. ⋯ Sites concerning TMD were poorly organized and maintained. Also, most sites contained insufficient or scientifically incorrect information that could have a negative effect on the treatment outcome and prognosis of TMD. Clinicians should guide patients to reputable sources of information that will enhance patient comprehension and better treatment outcomes.

To test the reliability and validity of a novel rat-holding device designed to be used in conjunction with the plantar test apparatus for studying nocifensive behavioral responses in an established model of temporomandibular joint (TMJ) pathology. ⋯ Findings from this study provide evidence to validate the use of this holding device for studying nocifensive behaviors in the orofacial region of rats in response to heat or mechanical orofacial stimulation.

To study the effect of estrogen deficiency and altered temporomandibular joint loading on the histomorphology of condylar cartilage and on the expression of types II and X collagen and matrix metalloproteinase-3 (MMP-3). ⋯ Condylar cartilage is sensitive to both estrogen level and dietary loading.
