Purpose Arthritis of the temporomandibular joint (TMJ) is a well recognized entity in patients with juvenile idiopathic arthritis (JIA). Recently, magnetic resonance imaging (MRI) evaluations have proven to have much greater sensitivity to detect arthritis compared to ultrasound and place the prevalence of TMJ arthritis in this population between 63% and 75%. There are a number of other rheumat...

Temporomandibular joint (TMJ) ankylosis is characterized by the formation of bony or fibrous mass, which replaces the normal articulation and limitation of mouth opening. This study aims to determine the efficacy of arthroplasty and interpositional fascia flap in the treatment of unilateral and bilateral TMJ ankylosis in three young adult men. Our operative protocol for unilateral and bilateral...

The temporomandibular joint (TMJ) connects the mandible to the skull. TMJ disorders induce degenerative tissue changes in TMJ disc that are largely the result of maladaption to abnormal joint loading. Histopathological studies have documented an association between TMJ arthropathy and loss of tissue cellularity, via apoptosis-related processes, that result in diminished extracellular matrix gen...

Temporomandibular joint (TMJ) dislocation has not previously been reported as a complication of beta-blocker toxicity. We are reporting two cases of TMJ dislocation resulted from acute severe intoxication with pure propranolol (PPL) for the first time. Bilateral TMJ dislocation happened in two patients who were admitted to intensive care unit with diagnosis of severe acute PPL toxicity. Clinica...

BACKGROUND The purpose of this study is to evaluate the outcomes of four patients receiving stock Biomet TMJ prosthesis for reconstruction of the TMJs. METHODS TMJ reconstruction with stock Biomet TMJ prosthesis was performed in four patients who had joint damages by trauma, tumor, resorption, and ankylosis, which represent the indications of alloplastic prosthesis. RESULTS Loss of condyle ...

The aims of this study were to investigate the influence of serotonin (5-HT) on the effects of intra-articular injections of glucocorticoid on pain of the temporomandibular joint (TMJ) in patients with inflammatory disorders of the TMJ. The pretreatment synovial fluid 5-HT was negatively, and plasma 5-HT positively, correlated to change in TMJ pain after treatment. The pretreatment plasma 5-HT ...

PURPOSE Neuropeptide-containing nerves can serve as a mechanism for nervous system regulation of host defense responses. Because bacteria associated with reactive arthritis have been identified in the temporomandibular joint (TMJ), this study investigates whether the presence of substance P (SP) neuropeptide-containing nerves and mast cells can be identified in the TMJ. MATERIAL AND METHODS P...
