To document the frequency of self-care in a clinical sample of patients with myofascial temporomandibular disorder (TMD) pain; report the perceived relief and control of pain for each of the self-care behaviors; and to test for associations between the frequency and efficacy of each self-care behavior and pain, depression and sleep quality, as assessed during a clinical visit, and to determine whether the frequency was associated with changes in pain intensity, depression, and sleep quality 30 days later. ⋯ Since people with chronic myofascial TMD pain engage in a range of pain self-care strategies, clinicians need to discuss self-care with patients regularly.
-
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 evaluate the sensitivity and reproducibility of a multimodal psychophysical technique for the assessment of both spatial and temporal changes in somatosensory function after an infraorbital nerve block. ⋯ The present findings indicate that the psychophysical method is sufficiently reproducible, with no major differences between sessions in healthy subjects. All stimulus modalities demonstrated adequate sensitivity. Furthermore, measurement of points in 5 x 5 matrices allowed a spatial description of somatosensory sensitivity. This method may be valuable for studies on changes in somatosensory sensitivity following trauma or orthognathic surgery on the maxilla.

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.

To determine intra- and interrater agreement of the pressure pain threshold (PPT) values for children reporting orofacial pain related to temporomadibular disorders and symptom-free subjects when the mean of 3 consecutive measurements or the mean of the last 2 consecutive measurements was considered. ⋯ The lower levels of reproducibility for the measurements obtained on different days in the children who reported pain may have been related to instability of their clinical signs and symptoms, and a PPT assessment based on the mean of 3 consecutive measurements or the procedure of discarding the first measure should be considered for such evaluations, especially when they are conducted by different raters. Algometry was shown to be a reliable tool for the evaluation of pain threshold in the masticatory structures of children.
