Temporomandibular joint (TMJ) disorders have complex and sometimes controversial etiologies. Also, under similar circumstances, one person's TMJ may appear to deteriorate, while another's does not. However, once degenerative changes start in the TMJ, this pathology can be crippling, leading to a variety of morphological and functional deformities. Primarily, TMJ disorders have a non-inflammator...

OBJECTIVE The purpose of this study was to evaluate displacement of the mandibular condyle after orthognathic surgery using a condylar-repositioning device. METHODS The patient group comprised 20 adults who underwent bimaxillary surgery between August 2008 and July 2011. The degree of condylar displacement was measured by pre- and postoperative tomographic analysis using centric relation bite...

Unilateral and bilateral involvement of the temporomandibular joint (TMJ) and subsequent growth disturbance of the mandibula is a common feature in juvenile idiopathic arthritis (JIA). The prevalence varies between 17% and 87% depending on the subtype of JIA. No conclusive measures for local disease activity are found. Arthritis of the TMJ is usually not associated with pain, and clinical signa...

Introduction: Degenerative changes in Temporomandibular Joint (TMJ) have increased in prevalence and severity over the years. Within this context, it’s necessary to obtain safe and effective therapies for control and management of the patient in cases of osteoarthritis and osteoarthrosis of the TMJ. Therapeutic options range from intra-articular infiltration protocols, occlusal splints, pharmac...

The most frequent intraarticular disorder of the temporomandibular joint (TMJ) represents the disorder of the functional relation between the articular disc and mandible condyle, i.e. dislocation of the articular disc. Magnetic resonance (MR) optimally visualizes the soft and hard articular tissues (articular disc, articular socket and condyle of the mandible) and its surroundings. The aim of t...

Temporomandibular disorders (TMDs) are a group of related disorders of the masticatory system (the masticatory musculature and the temporomandibular joint). The most frequent symptom is pain, usually localized in the muscles of mastication, the preauricular region, and the temporomandibular joint (TMJ). Patients often complain of jaw ache, earache, headache, and facial pain. In addition to pain...

This study is to investigate the changes of Temporomandibular Joint (TMJ) by experimentally induced osteoarthritis (OA) and to compare effectiveness of intraarticular injections. Intraarticular Monosodium Iodoacetate (MIA) solution was injected bilaterally to experimental groups to induce TMJ osteoarthritis. 0•9% NaCl solution was injected to TMJ of healthy control group bilaterally to investig...

We describe a rare case of osteochondroma of the coronoid process of mandible accompanied by severe trismus in a 14-year-old Japanese boy. The patient had initially been diagnosed as having internal derangement of the temporomandibular joint (TMJ), and conservative treatment had failed to improve the symptoms. Despite extremely limited TMJ movement, panoramic radiography revealed no abnormality...

Computed tomography (CT) and magnetic resonance (MR) image features of the temporomandibular joint (TMJ) and associated structures in two mature dromedary camels were obtained with a third-generation equipment CT and a superconducting magnet RM at 1.5 Tesla. Images were acquired in sagittal and transverse planes. Medical imaging processing with imaging software was applied to obtain postprocess...

PURPOSE Matrix metalloproteases (MMPs) are tissue-remodeling enzymes that function during the remodeling process, such as in immune-inflammatory diseases. Metalloprotease-2 (MMP-2) and metalloprotease-9 (MMP-9) are gelatinases that degrade several types of extracellular matrix collagen. It is hypothesized that in temporomandibular joint (TMJ) dysfunction, MMP-2 and MMP-9 expression levels may b...
