Temporomandibular joint (TMJ) complex is one of the most joints, which connects mandible to skull. This kind system has ability perform and bilateral movements. Due anatomy, there a need for thorough investigation find correct etiology TMJ disorders. For investigation, starting from clinical examination imaging strategies should be performed meticulously. Radiographic an important element in di...

The objective of this paper was to study the morphology of the articular disc and analyze the immunohistochemical expression of the marker of type IV collagen in the articular disc of the temporomandibular joint (TMJ) of human fetuses of different gestational ages. Twenty TMJ from human fetuses aging from 21 to 24 weeks of intrauterine life were studied. The TMJ were supplied by the Federal Uni...

Temporomandibular joint dysfunction (TMD) is a collection of clinical symptoms that involve masticatory muscles and the temporomandibular joint (TMJ). Common symptoms include limited jaw motion and joint sound/pain, along with TMJ disc displacement. TMD is frequently associated with synovitis, a chronic inflammation of the synovium. Fibroblast‑like synovial cells have been identified to produce...

Flake, Natasha M., Tracey O. Hermanstyne, and Michael S. Gold. Testosterone and estrogen have opposing actions on inflammation-induced plasma extravasation in the rat temporomandibular joint. Am J Physiol Regul Integr Comp Physiol 291: R343–R348, 2006. First published February 9, 2006; doi:10.1152/ajpregu.00835.2005.— The present study was designed to test the hypothesis that estrogen exacerbat...

Two cases of synovial chondromatosis of the temporomandibular joint (TMJ) are presented, including correlation of CT and MR imaging characteristics with surgical and pathologic findings. The usefulness of CT and MR imaging in the diagnosis of TMJ disorders is discussed.

PURPOSE Many different surgical techniques for the treatment of chronic recurrent temporomandibular joint (TMJ) dislocation have been described. This article discusses a technique of autologous blood injection to the TMJ for treatment of chronic recurrent TMJ dislocation. MATERIALS AND METHODS Twenty-five patients diagnosed with chronic recurrent TMJ dislocation were treated by bilateral inje...

Congenital temporomandibular joint (TMJ) diseases are very rare disorders and are usually diagnosed in childhood. Developmental disorders of the TMJ such as hypoplasia, hyperplasia, and aplasia of the TMJ compartments are characterized by TMJ dysfunction. In childhood, these patients experience recurrent dislocation, pain, and malocclusion. We present the case of a 25-week fetus with unilateral...

Recent recognition of the markedly high prevalence of temporomandibular joint (TMJ) arthritis in children with juvenile idiopathic arthritis (JIA) coupled with the significant morbidity associated with TMJ damage has prompted increased interest in both the clinical and pathological aspects of TMJ arthritis. This review focuses on the prevalence of TMJ arthritis in JIA, the imaging modalities us...

In this paper we investigate the relation between lateral crossbite disorders and the sounds generated by the Temporomandibular Joint (TMJ). TMJ vibrations are recorded clinically by palpation and auscultation and also electronically by accelerometers. TMJ signals are filtered, amplified, digitized and stored on a computer. Based on joint time-frequency moments calculated from evolutionary spec...

Temporomandibular joint (TMJ) sound is one of the most commonly recognized signs in patients with temporomandibular disorders (TMD) but is also frequently seen in asymptomatic individuals. Sound recording is therefore only meaningful if the sounds from a normal healthy joint can be differentiated from those in patients. In this study, the amplitude and power spectrum of the TMJ sounds from symp...
