To explore the impact of trigeminal nerve injuries on quality of life, including the effect of pain on psychological and affective function. ⋯ Traumatic injury to the trigeminal nerve is associated with a substantial patient burden, particularly in patients who experience severe neuropathic pain as part of their condition. These findings highlight the need to identify, develop, and evaluate more effective treatments for neuropathic pain in trigeminal nerve injury that will not only provide clinically meaningful reductions in pain but also improve patients' quality of life.

Comparative Study
Neuromuscular interaction of jaw and neck muscles during jaw clenching.
To test the hypothesis that jaw muscles and specific neck muscles, ie, levator scapulae, trapezius, sternocleidomastoideus, and splenius capitis, co-contract at the different submaximum bite forces usually generated during jaw clenching and tooth grinding, and for different bite force directions. ⋯ The findings support the assumption of a relationship between jaw clenching and the neck muscle activity investigated. The low level of co-contraction activity, however, requires further study to elucidate possible pathophysiological interactions at the level of single motor units.

To investigate the hypothesis that the presence of transient morning masticatory muscle pain in young, healthy sleep bruxers (SBr) is associated with sex-related differences in sleep electroencephalographic (EEG) activity. ⋯ Female SBr had lower theta and alpha EEG activity irrespective of transient morning pain.

To translate the Pictorial Representation of Illness and Self Measure (PRISM) instrument from German to Portuguese (Brazilian) and adapt it to the Brazilian cultural context, and then assess its reliability and validity in orofacial pain patients. ⋯ The cross-cultural adaptation process of PRISM was successful and the adapted version offers reliable and valid psychometric properties in the Brazilian context.

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.
