To test in vitro and in vivo the reliability and accuracy of a new algometer, the pressure algometer for palpation (PAP), for measuring pressure pain thresholds (PPTs) and to compare its features with those of a commercially available pressure algometer. ⋯ Both the PAP and the Somedic algometer showed high reliability. Concurrent validity was demonstrated by statistically significant correlations between the devices. Both showed equally high capacity for differentiating TMD cases from controls. The PAP yielded significantly higher PPTs than the Somedic algometer.

To develop and validate a questionnaire-based tool which would enable classification of idiopathic orofacial pain in the general population. ⋯ The classification criteria developed for idiopathic orofacial pain can be used as a screening tool for subjects with this condition in the general population.

To examine differences in temporal summation of mechanically evoked pain between women and men suffering from chronic pain associated with temporomandibular disorders (TMD), as well as between male TMD patients and healthy controls. ⋯ These findings suggest that central nociceptive processing upregulation is likely to contribute to TMD pain for women but is not a factor for

To evaluate temporomandibular disorder (TMD) patients for differences between masticatory muscle (MM) and temporomandibular joint (TMJ) pain patients in the prevalence of posttraumatic stress disorder (PTSD) symptoms and evaluate the level of psychological dysfunction and its relationship to PTSD symptoms in these patients. ⋯ A somewhat elevated prevalence rate for PTSD symptomatology was found in the MM group compared to the TMJ group. Significant levels of psychological dysfunction appeared to be linked to TMD patients with PTSD symptoms.
