Comparative Study
Women with Ehlers-Danlos syndrome experience low oral health-related quality of life.
To investigate the perceived impact of oral health-related quality of life problems in individuals with Ehlers-Danlos syndrome. ⋯ It is well-known that Ehlers-Danlos syndrome has a considerable impact on health-related quality of life, and this study is the first to reveal that women with Ehlers-Danlos syndrome report a low oral health-related quality of life as measured with the OHIP-14. Dimensions that were particularly relevant were physical pain, psychologic discomfort, and handicap.

To conduct a clinical electrophysiologic evaluation of autonomic nervous system functions in patients with burning mouth syndrome and Parkinson disease and estimate the type and intensity of the autonomic dysfunction. ⋯ In patients with burning mouth syndrome, a significant impairment of both the sympathetic and parasympathetic nervous systems was found but sympathetic/parasympathetic balance was preserved. The incidence and intensity of autonomic nervous system dysfunction was similar in patients with burning mouth syndrome and Parkinson disease, which may suggest some similarity in their pathogeneses.

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 hypothesis that estimates of time spent in tooth contact are significantly greater than estimates of time spent clenching, and to test the hypothesis that tooth contact is greater in pain patients, particularly those reporting facial or head pain, than those with pain elsewhere in the body. ⋯ Results from the logistic regressions provide convergent validity on the importance of oral parafunctions, specifically tooth contact and clenching, to facial/head pain. For assessment of oral parafunctional behaviors, inquiries that utilize clear behavioral referents (tooth contact versus clenching) are likely to result in more accurate estimates than behaviors with unclear definitions.

Randomized Controlled Trial Comparative Study
Assessment of proprioceptive allodynia after tooth-clenching exercises.
To (A) evaluate test-retest reliability of vibrotactile sensitivity in the masseter muscle and (B) test if (1) the vibration threshold is decreased after experimental tooth clenching, (2) intense vibrations exacerbate pain after tooth clenching, (3) pain and fatigue are increased after tooth clenching, and (4) pressure pain thresholds are decreased after tooth clenching. ⋯ Experimental tooth clenching appears to evoke moderate levels of pain and fatigue and short-lasting hyperalgesia to mechanical stimulation, but not proprioceptive allodynia. The absence of proprioceptive allodynia does not necessarily exclude delayed onset muscle soreness (DOMS) but warrants further studies on the clinical manifestations of DOMS in jaw muscles.
