We have previously shown that injection of mustard oil or glutamate into rat temporomandibular joint (TMJ) tissues, an experimental model of acute TMJ injury, can reflexly induce a prolonged increase in the activity of both digastric (jaw-opener) and masseter (jaw-closer) muscles. In this study, GABA was applied to the TMJ region by itself or in combination with glutamate, and the magnitude of ...

AIM A study was performed on the articular disk and periarticular tissues of the temporo-mandibular joint (TMJ) with immunohistochemical techniques to give evidence to the presence of neuroreceptors (NRec) in these sites. METHODS The study was carried out on tissue samples obtained from 10 subjects without TMJ disease and from 7 patients with severe TMJ arthritis and arthrosis. We use antibod...

PURPOSE We review published research on temporomandibular joint (TMJ) total replacement that compares costochondral graft and customized total joint reconstruction (especially TMJ concepts), focusing on effectiveness. METHODS We searched PubMed databases, including prospective, retrospective, case-control or longitudinal studies and significant statistical analysis. In data analysis, we divid...

Compressive stress may be involved in temporomandibular joint (TMJ) synovitis, but its mechanism has not been fully elucidated. We hypothesized that mechanical stress to the synovial cells of the TMJ potentially causes degenerative changes in temporomandibular joint disease. We examined the effect of cyclic compressive loading on three-dimensionally engineered constructs using human TMJ synoviu...

A case of a patient with a fracture of the temporomandibular joint (TMJ) disk is reported. The patient presented with posterior bilateral open-bite and difficulty to chew due to lack of contact between the posterior teeth. Diagnosis of disk fracture of the right TMJ was made based on magnetic resonance imaging (MRI), with posterior displacement of the posterior fragment of the disk, causing the...

Background: Palpation is a crucial component of the temporomandibular joint (TMJ) examination in identifying tenderness. One-finger one-point palpation has high tendency for inappropriate application and misinterpretation.
 Objective: To evaluate three-point vs determination TMJ tenderness.
 Patients Methods: The study included fourth fifth-year students College Dentistry/Hawler Medic...

Temporo Mandibular Joint (TMJ) and its normal function are of great importance for the development of the mandible and craniomandibular region [1]. In growing individuals, trauma and pathology of the TMJ has a chronic impact on both the condylar development and the total morphology of the mandible [2]. Over time, the growth under influence of the pathogenesis of the TMJ will be reflected in the...

clinical treatments for patients with TMJ-OA focused only on the relief from orofacial pain caused by progressive de-generation of the articular cartilage. Therefore, as a strategy for maintaining the homeostasis of the synovial joints, recent studies on preventive medicine for OA attempted to shift the metabolic status of the joints from the catabolic to the ana-bolic state using anabolic mate...

Extended postoperative mandibular reconstructions due to orofacial disease involving the temporomandibular joint (TMJ) in immature patients remain a challenge as result of ongoing growth, which is usually affected by and treatment. Current reconstructive techniques based fully on alloplastic total replacement fail meet anatomical functional requirements for masticatory system speech development...

Total joint replacement (TJR) with a prosthesis can be indicated for patients severe temporomandibular (TMJ) dysfunction. Surgical accuracy is necessary correct translation of the preoperatively predicted functional outcome, wear, and biomechanical behaviour patient-specific TMJ-TJR prosthesis. This study describes first clinical applications according to Groningen principles (G-TMJ-TJR), which...
