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.

This topical review presents an overview of orofacial manifestations associated with the more common connective tissue diseases affecting multiple organs. The orofacial manifestations associated with these autoimmune disorders include oral mucosa alterations, salivary gland pathosis, sensory neuropathies, headaches, and temporomandibular disorders. ⋯ An understanding of the orofacial manifestations associated with these systemic diseases will enable the pain practitioner to establish an appropriate diagnosis within the context of the underlying systemic disease. This will allow the practitioner the opportunity to contribute and collaborate as a member of a multidisciplinary health-care team in the management of these systemic autoimmune diseases.

Randomized Controlled Trial
Effect of a peripheral NMDA receptor antagonist on glutamate-evoked masseter muscle pain and mechanical sensitization in women.
To test the hypothesis that local injection of the N-methyl-D-aspartate (NMDA) receptor antagonist ketamine would significantly attenuate glutamate-evoked masseter mechanical sensitization and muscle pain in healthy young women either taking oral contraceptives (W+OC) or not taking oral contraceptives (W-OC). ⋯ Peripherally administered ketamine had no effect on glutamate-evoked masseter muscle pain and sensitization in healthy young women, which contrasts with recent observations in healthy young men. Further studies will be needed to reveal the mechanisms that underlie this apparent sex-related difference in ketamine-mediated analgesia.

Comparative Study
Orofacial pain conditions and impact on quality of life in community-dwelling elderly people in Hong Kong.
To determine orofacial pain (OFP) characteristics, associated disability, and effect on quality of life in elderly community-dwelling Chinese people. ⋯ OFP had a substantial detrimental impact on daily life activities, psychological distress level, and quality of life in Chinese elders. MST and DA conditions had the greatest adverse impact on quality of life.
