Purpose To evaluate osseous changes of temporomandibular joint (TMJ) in patients with rheumatoid arthritis (RA) using cone-beam computed tomography (CBCT) and to correlate the imaging findings with the severity of TMJ dysfunction, clinical findings, and laboratory findings. Materials and Methods This study consisted of 28 subjects, including 14 RA patients and 14 controls, who were scheduled ...

INTRODUCTION This study was to investigate whether there was statistical difference between the bilateral temporomandibular joint (TMJ) in patients with unilateral TMJ pain or joint sounds, using cone beam computed tomography (CBCT). METHODS TMJ CBCT images of 123 cases were used to preliminarily determine the indicators suitable for the measuring method. TMJ CBCT image reconstruction was per...

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...

temporomandibular disorders (tmd) are clinical conditions characterized by pain and sounds of the temporomandibular joint (tmj). this study was designed to assess the effect of low-level laser therapy (lllt) on healing of osteoarthritis in rats with tmd.thirty-two male wistar rats (250-200 g) were housed in standard plastic cages. after injection of complete freund's adjuvant into the tmj, rats...

Introduction: The temporomandibular joint (TMJ) is a synovial joint that has a fibrocartilaginous articular disc located between the articular cartilage of the articular eminence of the temporal bone and the mandibular condyle. As masticatory muscles maintain the integrity of the TMJ, the components of the TMJ are constantly compressed during occlusion. During mastication, muscle contractions a...

TMJ disc related diseases are difficult to be cured due to the poor repair ability of the disc. TMJ-SDSCs were ideal cell sources for cartilage tissue engineering which have been widely used in hyaline cartilage regeneration. Fibrin gel has been demonstrated as a potential scaffold for neocartilage formation. The aim of this study was to repair the TMJ disc perforation using fibrin/chitosan hyb...

BUMC PROCEEDINGS 2000;13:135–138 Jaw joint (temporomandibular joint or TMJ) disease is estimated to affect 30 million Americans, with approximately 1 million new patients diagnosed each year (1). Although many of these patients can be managed with nonsurgical therapies, some patients require surgical intervention. The TMJ is a unique joint in that it does not function independently but works in...

BACKGROUND In massive rotator cuff tears a teres major (TMj) tendon transfer to the insertion of the supraspinatus (SSp) reverses its adduction moment arm into abduction which is supposed to be an adequate salvage procedure. Analysis of muscle function to find biomechanical ground of such success is scarce. METHODS We compared pre- and postoperative clinical outcome of TMj transfer, i.e. Rang...

Chronic recurrent temporomandibular joint (TMJ) dislocation is defined as the complete loss of articular relationships, during mouth-wide opening, between the articular fossa of the temporal bone and the condyle-disk complex. The most frequent pathogenetic factors involved in chronic recurrent dislocation of the TMJ are supposed to be trauma, abnormal chewing movements, TMJ ligaments, capsule l...

OBJECTIVE Implantation of synthetic temporomandibular joint (TMJ) disc replacements aimed to alleviate pain and restore functional losses caused by TMJ disorders. Unfortunately, these synthetic replacements have been largely unsuccessful and in some instances have incited severe immune responses. Tissue engineering, however, may provide viable TMJ disc replacements. Towards this end, we have st...
