To test whether patients with temporomandibular disorder (TMD) pain differ from subjects from the general population with regard to their stress-related coping styles. ⋯ Differences in the applied stress-related coping styles of TMD patients and subjects without TMD may have implications for clinical decision making and choosing among treatment alternatives.
-
To test the reliability and validity of a novel rat-holding device designed to be used in conjunction with the plantar test apparatus for studying nocifensive behavioral responses in an established model of temporomandibular joint (TMJ) pathology. ⋯ Findings from this study provide evidence to validate the use of this holding device for studying nocifensive behaviors in the orofacial region of rats in response to heat or mechanical orofacial stimulation.
-
To determine the available evidence in the literature for whether hypoxia-reperfusion injury plays a role in the pathogenesis of joint diseases in general and of osteoarthritis (OA) of the temporomandibular joint (TMJ) in particular. ⋯ There is no evidence to support or reject the hypothesis that hypoxia reperfusion occurs in TMJ OA, and limited evidence is provided to support that hypoxia-reperfusion injury occurs in OA of the knee joint. Since the studies suggest differences between OA and other types of arthritis in relation to hypoxia-reperfusion mechanisms, further research in this field needs to distinguish OA from other types of arthritis.
-
To test the hypothesis that the effects of an experimental occlusal interference differ between individuals reporting a high or low frequency of wake-time oral parafunctions. ⋯ The application of an experimental occlusal interference has a different effect in individuals reporting a high or low frequency of oral parafunctions.

To evaluate the concordance among different pain scales for evaluation of pain in toothache patients and to assess the influence of oral health on the quality of life of those patients. ⋯ All scales were able to detect differences in the pain reported after dental treatment and may be valid and reliable for use in clinical dental practice. The NS, however, returns higher scores at baseline when assessing the pain.
