Comparative Study
Effect of jaw muscle pain and soreness evoked by capsaicin before sleep on orofacial motor activity during sleep.
Sleep bruxism, which is a form of orofacial motor activity (OMA), and jaw muscle pain and soreness have for a long time been thought to be mutually linked. The aim of this study was to investigate the effect of clinical and experimental jaw muscle pain and soreness on sleep OMA. ⋯ This study suggests that an acute pre-sleep painful stimulus does not have any effect on OMA during sleep, but the study extends previous findings that clinical jaw muscle pain and soreness are associated with less EMG activity in the masticatory muscles.

To determine psychosocial predictors of patients' ratings of satisfaction with improvement and subjective pain relief. This study also examined the underlying components of patient satisfaction with improvement, as assessed at follow-up. ⋯ This study is one of the first to report that the use of certain cognitive coping strategies is associated with positive outcome for patients suffering from orofacial pain. These findings underscore the importance of individual differences on behavioral and psychosocial parameters in the prediction of patients' subjective evaluation of treatment outcome.

Randomized Controlled Trial Comparative Study Clinical Trial
Physical self-regulation training for the management of temporomandibular disorders.
To evaluate the long-term effectiveness of a brief skills training program for the management of chronic facial muscle pain. This program of physical self-regulation (PSR) involved primarily training in breathing, postural relaxation, and proprioceptive re-education. ⋯ The findings support the use of PSR for the short- and long-term management of muscle pain in the facial region. These results are discussed in terms of the potential mechanisms by which self-regulation treatment strategies are effective for the management of these pain disorders.

To determine whether sex differences exist in tissue oxygen saturation (StO2) and the hemoglobin (Hb) oxygenation state of the resting human masseter muscle. ⋯ These results provide evidence that a sex difference in the Hb oxygenation state may exist in the masseter muscle of normal healthy subjects.
