Randomized Controlled TrialGlutamate-evoked jaw muscle pain as a model of persistent myofascial TMD pain?
Compare pain-related measures and psychosocial variables between glutamate-evoked jaw muscle pain in healthy subjects (HS) and patients with persistent myofascial temporomandibular disorder (TMD) pain. ⋯ Glutamate-evoked pain responses in HS and persistent myofascial TMD pain have similar sensory-discriminative and affective-unpleasantness components but differ in psychosocial features. This study suggests that experimental designs based on glutamate injection into muscle can provide an appropriate model for elucidating persistent myofascial pain conditions.

Fluid dynamics of gingiva in diabetic and systemically healthy periodontitis patients.
The influence of diabetes mellitus (DM) on the fluid dynamics of periodontium has not been reported in periodontal disease. The objectives of this study were (i) to investigate the alterations in the fluid dynamics of periodontium in diabetic periodontitis patients, and present the association of this phenomenon with the metabolic control of DM; (ii) to reveal any correlation between the fluid dynamics of periodontium and clinical signs of periodontal disease in DM and periodontitis. ⋯ The results suggest that (i) DM may have an additive influence on the fluid dynamics of periodontium in the presence of periodontal disease; (ii) this phenomenon may not be prevented by the metabolic control of DM; (iii) the clinical signs of periodontal disease may be affected by the fluid dynamics of periodontium in both DM and periodontitis.
