Review Meta Analysis Comparative Study
Lavage therapy versus nonsurgical therapy for the treatment of arthralgia of the temporomandibular joint: a systematic review of randomized controlled trials.
To carry out a systematic review of randomized controlled trials (RCTs) to investigate in patients with arthralgia of the temporomandibular joint (TMJ) the effectiveness of TMJ lavage compared to nonsurgical treatment with regard to pain intensity and mandibular range of motion. ⋯ The results suggest that lavage of the TMJ may be slightly more effective than nonsurgical treatment for pain reduction. However, this difference is not likely to be clinically relevant.

To assess, by systematic review of the literature, (1) the prevalence and incidence of temporomandibular disorder (TMD) pain after whiplash trauma, and (2) whether treatment modalities commonly used for TMD are equally effective in patients with solely TMD pain and those with TMD/whiplash-associated disorders (WAD) pain. ⋯ There is some evidence that prevalence and incidence of TMD pain is increased after whiplash trauma. The poorer treatment outcome suggests that TMD pain after whiplash trauma has a different pathophysiology compared to TMD pain localized to the facial region.

To investigate thermal thresholds of selected orofacial sites, determine if there is a relationship between thermal thresholds at each site, and analyze the influence of two different baseline temperatures on thermal thresholds at the tongue tip. ⋯ Thermal thresholds varied between the orofacial test sites, and baseline temperature affected thermal sensitivity of the tongue. Subjects who were relatively sensitive to cold tended to be more sensitive to heat.
-
To examine sleep complaints in patients with burning mouth syndrome (BMS) and the relationships between these disturbances, negative mood, and pain. ⋯ BMS patients reported a greater degree of sleep disorders, anxiety, and depression as compared with controls. Sleep disorders could influence quality of life of BMS patients and could be a possible treatment target.

Randomized Controlled Trial
Effect of propranolol on hypertonic saline-evoked masseter muscle pain and autonomic response in healthy women during rest and mental arithmetic task.
To investigate in a randomized, double-blinded, placebo controlled, crossover study the effect of a single dose of the nonselective β-adrenergic receptor antagonist propranolol (40 mg) on hypertonic saline (HS)-evoked masseter muscle pain and autonomic activity during rest and during a mental arithmetic task (Paced Auditory Serial Addition Task, PASAT). ⋯ A single dose of propranolol had no effect on acute HS-evoked pain levels during rest or during mental arousal. However, it influenced the tone of the autonomic nervous system, possibly reflecting an anxiolytic effect.
