Randomized Controlled Trial Comparative Study
Experimental tooth clenching. A model for studying mechanisms of muscle pain.
The overall goal of this thesis was to broaden knowledge of pain mechanisms in myofascial temporomandibular disorders (M-TMD). The specific aims were to: Develop a quality assessment tool for experimental bruxism studies (study I). Investigate proprioceptive allodynia after experimental tooth clenching exercises (study II). ⋯ In healthy subjects and in patients with M-TMD, levels of 5-HT, glutamate, pyruvate, and lactate were unaltered after tooth clenching. But 5-HT levels were significantly higher and blood flows significantly lower in M-TMD patients than in healthy controls at all time points. These two factors may facilitate the release, and enhance the effects, of other algesic substances that may cause pain.

Review Randomized Controlled Trial Clinical Trial
Temporomandibular disorders in adolescents. Epidemiological and methodological studies and a randomized controlled trial.
The aim of the present thesis was to investigate different aspects of temporomandibular disorders (TMD) and pain such as prevalence, diagnostics, and treatment among adolescents. The reliability of a questionnaire and the clinical examination and diagnoses according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were assessed. Overall, we found it possible to assess and diagnose TMD in adolescents in a reliable way. ⋯ The results suggest that not only nociceptive but also cognitive processes are implicated in chronic pain states in young TMD subjects. In conclusion, TMD pain is more common in girls than in boys and affects daily life. TMD pain in adolescents can best be improved by traditional treatment with occlusal appliance combined with brief information.

Randomized Controlled Trial Comparative Study Clinical Trial
Acupuncture in the treatment of patients with craniomandibular disorders. Comparative, longitudinal and methodological studies.
The aim of the thesis was to compare the short- and long-term effects of acupuncture and occlusal splint therapy in patients with craniomandibular disorders (CMD). One hundred and ten patients, 23 males and 87 females, participated in the study. All patients exhibited moderate or severe signs and symptoms of CMD and had had pain for more than six months. ⋯ The algometer was sensitive enough to detect pre- and post-treatment changes. A statistically significant reduction in tenderness was found immediately after and at the 6-month follow-up for both treatment modes. This series of studies showed that acupuncture gave positive results similar to those of occlusal splint therapy in patients with primarily myogenic CMD symptoms over a 1-year period.
