Development of a quality-assessment tool for experimental bruxism studies: reliability and validity.
To combine empirical evidence and expert opinion in a formal consensus method in order to develop a quality-assessment tool for experimental bruxism studies in systematic reviews. ⋯ Qu-ATEBS, the seven-item evidence-based quality assessment tool developed here for use in systematic reviews of experimental bruxism studies, exhibits face validity, excellent discriminative validity, and acceptable inter-observer reliability. Development of quality assessment tools for many other topics in the orofacial pain literature is needed and may follow the described procedure.

Comparative Study Clinical Trial
Effect of contingent electrical stimulation on masticatory muscle activity and pain in patients with a myofascial temporomandibular disorder and sleep bruxism.
To determine whether an intervention reduces oromotor activity and masticatory muscle pain in myofascial temporomandibular disorder (M/TMD) patients with high levels of masticatory muscle activity associated with sleep bruxism. ⋯ Spontaneous pain severity and nighttime oromotor activity vary independently over nights, even in M/TMD patients selected for relatively high levels of both characteristics.

To assess the influence of myofascial temporomandibular disorder (TMD) pain on the pressure pain threshold (PPT) of masticatory muscles in women during a migraine attack. ⋯ Migraine attack is associated with a significant reduction in PPT values of masticatory muscles, which appears to be influenced by the presence of myofascial TMD pain.

Cutaneous mastocytosis (CM) has been associated with urticaria, itching, and pain of the affected regions. Although the occurrence of CM in the facial skin is rare, it may be a cause of chronic facial pain, and pain characteristics may mistakenly be interpreted as trigeminal nerve pathology. However, the dermatological appearance of the different variants of cutaneous mastocytosis is distinct and should be considered as an uncommon differential diagnosis in an orofacial pain diagnostic algorithm. This article presents a case of telangiectasia macularis eruptiva perstans, a rare type of cutaneous mastocytosis, as the underlying cause of chronic facial pain, erythema, and swelling.

To assess Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis II variables in an initial psychosocial screening and as a part of biopsychosocial subtyping of Finnish referral patients with TMD pain for adjunct multidisciplinary assessment. ⋯ The Finnish RDC/TMD Axis II was found reliable in initial TMD pain patient screening and with further biopsychosocial assessment identified three main TMD subtypes, two with compromised psychosocial profiles for adjunct multidisciplinary assessment.
