Comparative Study
The influence of experimentally induced osteoarthrosis on articular nerve fibers of the sheep temporomandibular joint.
To study the effect of experimentally induced osteoarthrosis, or non-inflammatory degenerative changes, on the innervation of the sheep temporomandibular joint (TMJ) through the use of indirect immunohistochemistry and image analysis quantification. ⋯ This study suggests that while inflammatory arthritis has a marked influence on the density of sensory and autonomic nerve fibers in synovium in a variety of joints in different species, experimentally induced non-inflammatory osteoarthrosis in the sheep TMJ also leads to a depletion of the density of nerve fibers in the capsule, especially in the lateral part of the joint. Further work is required to determine whether other parts of the joint, such as synovium and marrow, respond differently to experimentally induced osteoarthrosis.

Randomized Controlled Trial Comparative Study Clinical Trial
Diffusion model of pain language and quality of life in orofacial pain patients.
To address the following questions: (1) Which words are preferred by different groups of orofacial pain patients to describe their pain experience? (2) Is it possible, based on such descriptions, to obtain a clinical differential diagnosis in these patients? (3) Is there any relationship between the verbal description of pain and self-rated quality of life (QOL)? (4) Can a pattern of modulation of pain language by affective variables (diffusion model) be recognized in orofacial pain patients, as it has in other chronic pain patients? and (5) If so, what might be the clinical usefulness of assessing pain language in these patients? ⋯ Although trends in patients' choice of descriptors were evident, differential diagnosis based on only a pain questionnaire was not possible in the different groups of orofacial pain patients examined in this study. The present study suggests the presence of a phenomenon of diffusion in the language of those patients who were experiencing a worsening of their QOL as a result of pain and consequent psychologic distress. This observation can be of clinical usefulness by enhancing the sensitivity of the clinician to the suffering and affective distress experienced by the patient, and it also can be helpful in refining the therapeutic approach for each individual patient.

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.
