Although a recent study suggested the involvement of RANKL and osteoprotegerin (OPG) in the pathogenesis of bone-destructive disease, no study has focused on the RANKL:OPG ratio in the synovial fluid of patients with temporomandibular joint (TMJ) disorder. This communication reports on the concentrations of RANKL and OPG in synovial fluid from TMJ patients and healthy control individuals. In co...

The treatment of the temporomandibular joint (TMJ) is still controversial. TMJ arthrocentesis represents a form of minimally invasive surgical treatment in patients suffering from internal derangement of the TMJ, especially closed lock. It consists of washing the joint with the possibility of depositing a drug or other therapeutic substance. Resolution of symptoms is due to the removal of chemi...

Introduction Gout is an illness characterized by the deposition of monosodium urate crystals in the joints or in soft tissues. The clinical manifestation results from inflammation of limb joints and pain with a rare presentation in the temporomandibular joint (TMJ). Case Report This study describes a 66-year-old white man with a chief complaint of "occasional pain in the left temporal muscle re...

The need to visualize soft-tissue components of the temporomandibular joint (TMJ) and the knowledge of the growing use of computed tomography (CT) in medical diagnostic imaging prompted one author (E. L. C.) to consider its potential for TMJ evaluation. The experience with our first patient who had an anteriorly dislocated joint disk has stimulated the use of CT for patients in the TMJ clinic. ...

effects of intra-articular administration of granisetron on temporomandibular joint (TMJ) pain was investigated in 11 patients with chronic polyarthritides. An analgesic effect superior to placebo has been shown previously. The change in TMJ movement pain intensity was negatively correlated to circulating 5-HT; that is, the higher the 5-HT before injection, the greater the reduction of pain int...

Metastases or tumour to the jaws are rare and those to the temporomandibular joint (TMJ) are even rarer. The symptoms like preauricular pain, swelling and clicking are generally associated with TMJ disease. But the same symptoms are also found in tumours of the jaws or other diseases. We report on the case of a 48-year-old woman with a 12-year history of breast cancer who was referred to our de...

The aim was to investigate whether bone tissue resorption in early RA is related to crepitus of the temporomandibular joint (TMJ) and systemic levels of inflammatory mediators and markers and sex steroid hormones. Twentynine women and 18 men with recently diagnosed RA were examined for TMJ bone erosions with computerized tomography and TMJ crepitus was assessed. Blood samples were analyzed for ...

The aim of this study was to assess the shape of the temporomandibular joint (TMJ) articular eminence and the articular disc configuration and position in patients with disc displacement. TMJ magnetic resonance images (MRI) of 14 patients with bilateral disc displacement without unilateral reduction were analyzed. Articular eminence morphology was characterized as box, sigmoid, flattened, or de...

We evaluated the soft tissue of the temporomandibular joint (TMJ) with magnetic resonance imaging (MRI) after intracapsular condylar fracture. Eighteen consecutive patients (19 TMJ) were diagnosed between 1 January 2010 and 30 October 2011. They were examined using bilateral sagittal and coronal MRI, which were obtained immediately after injury to assess the displacement of the disc, whether th...

The aim of this study was to investigate the influence of tumor necrosis factor-alpha (TNF-alpha) in temporomandibular joint (TMJ) synovial fluid and blood on the treatment effect on TMJ pain by intra-articular injection of glucocorticoid in patients with chronic inflammatory TMJ disorders. High pretreatment level of TNF-alpha in the synovial fluid was associated with a decrease of TNF-alpha an...
