UNLABELLED In our study, we investigated the predictive value of illness beliefs as measured by the revised illness perception questionnaire (IPQ-R) in the context of other clinical predictors in patients with chronic orofacial pain over a 6-month follow-up period. Consecutive patients (152) referred to the interdisciplinary orofacial pain service at the Centre for Dental and Oral Medicine and ...

Forty-six patients presenting with chronic orofacial muscle pain and eight age- and sex-matched control subjects were investigated for the carriage prevalence of, and exotoxin production by, coagulase-negative staphylococci (CNS). The eight control subjects were selected from an initial group of 41 subjects on the basis of the absence of musculoskeletal symptoms. There was a significantly highe...

OBJECTIVES This study aimed to clarify the roles of Acid-sensing ion channel 3 (ASIC3) in orofacial pain following experimental tooth movement. MATERIALS AND METHODS Sixty male Sprague-Dawley rats were divided into the experimental group (40g, n = 30) and the sham group (0g, n = 30). Closed coil springs were ligated between maxillary incisor and molars to achieve experimental tooth movement. ...

BACKGROUND Most people are initially infected with varicella zoster virus (VZV) at a young age and this infection results in chickenpox. VZV then becomes latent and reactivates later in life resulting in herpes zoster (HZ) or "shingles". Often VZV infects neurons of the trigeminal ganglia to cause ocular problems, orofacial disease and occasionally a chronic pain condition termed post-herpetic ...

Conditions involving chronic orofacial pain represent a major health problem, and patients with persistent pain are difficult to manage successfully. These conditions are often comorbid with additional health issues such as sleep disturbances, cardiovascular, gastrointestinal and reproductive system complaints, weight loss or weight gain, swelling, numbness, sweating and flushing, and concerns ...

BACKGROUND Temporomandibular disorder (TMD) is described as a subgroup of orofacial pain with a set of signs and symptoms that involve the temporomandibular joint, masticatory muscles, ears, and neck. TMD can occur unilaterally or bilaterally and approximately 70% of the population is affected with at least one sign. The disorder progresses with orofacial pain, muscle pain involving the mastica...

Patient. The patient was a 68-year-old man who suffered from inveterate pain with trophic changes of the right face and tongue and vasomotor dysfunction on the right side of the face after ...

currently, localized pulpalgia is listed as a rare manifestation of chemotherapy treatments in patients with malignant tumors.  the neuropathy originated from neurotoxicity of anticancer drugs is usually described as a diffuse jaw pain or numbness in orofacial structures. this article reports localized tooth pain as a possible outcome of administrating high dosage chemotherapy drugs particularl...

PURPOSE Although mechanical overloading of the temporomandibular joint (TMJ) is implicated in TMJ osteoarthritis (OA) and orofacial pain, most experimental models of TMJ-OA induce only acute and resolving pain, which do not meaningfully simulate the pathomechanisms of TMJ-OA in patients with chronic pain. The aim of this study was to adapt an existing rat model of mechanically induced TMJ-OA, t...
