According to the Generalized Hypervigilance Hypothesis (GHH) of McDermid et al., the unpleasantness of sensory stimuli, rather than their modality, determines whether they will be perceptually amplified in hypervigilant persons. In a test of this idea, ratings of the intensity of sensations evoked by cutaneous and auditory stimuli were obtained from(More)
OBJECTIVES The aim of this study is to examine the difference in the report of bodily pain experienced by patients who develop temporomandibular disorders (TMD) and by those who do not develop TMD over a 3-year observation period. METHODS This is a 3-year prospective study of 266 females aged 18 to 34 years initially free of TMD pain. All patients(More)
OBJECTIVES The purpose of this study was to determine whether bony changes in temporomandibular joint (TMJ) osteoarthritis (OA) is correlated with pain and other clinical signs and symptoms. METHODS Clinical data and cone beam CT (CBCT) images of 30 patients with TMJ OA were analysed. The criteria of Koyama et al (Koyama J, Nishiyama H, Hayashi T.(More)
INTRODUCTION Three common haplotypes in the gene encoding catechol-O-methyltransferase (COMT) have been associated with pain modulation and the risk of developing chronic musculoskeletal pain, namely temporomandibular disorder (TMD). Haplotypes coding for higher enzymatic activity were correlated with lower pain perception. Rodent studies showed that COMT(More)
UNLABELLED This paper describes methods used in the project "Orofacial Pain Prospective Evaluation and Risk Assessment" (OPPERA) and evaluates sociodemographic characteristics associated with temporomandibular disorders (TMD) in the OPPERA case-control study. Representativeness was investigated by comparing sociodemographic profiles of OPPERA participants(More)
OBJECTIVE This study was performed to determine the condylar morphologic variation of osteoarthritic (OA) and asymptomatic temporomandibular joints (TMJs) and to determine its correlation with pain intensity and duration. STUDY DESIGN Three-dimensional surface models of mandibular condyles were constructed from cone-beam computerized tomography images of(More)
UNLABELLED The multiple bodily pain conditions in temporomandibular disorders (TMD) have been associated with generalized alterations in pain processing. The purpose of this study was to examine the relationship between the presence of widespread body palpation tenderness (WPT) and the likelihood of multiple comorbid pain conditions in TMD patients and(More)
OBJECTIVE To assess 3D morphological variations and local and systemic biomarker profiles in subjects with a diagnosis of temporomandibular joint osteoarthritis (TMJ OA). DESIGN Twenty-eight patients with long-term TMJ OA (39.9 ± 16 years), 12 patients at initial diagnosis of OA (47.4 ± 16.1 years), and 12 healthy controls (41.8 ± 12.2 years) were(More)
SUMMARY Chronic widespread pain (CWP) represents pain involving several regions of the body. Various psychological and social risk factors such as poor general health status, sleep disturbance, fatigue and high psychological distress have been identified for the development of CWP. Numerous chronic pain conditions are comorbid, resulting in the development(More)
