The use of pseudo-dynamic magnetic resonance imaging for evaluating the relationship between temporomandibular joint anterior disc displacement and joint pain

TMJ imaging in JIA patients—An overview

“…In this age group, TMJ dysfunction is quite common in the general population, and the dysfunction is frequently related to disc displacement and osteoarthritis. 80,81 Similar observations are made in the pediatric age group. 82,83 In adults, adolescents, and children such TMJ dysfunction may be a differential diagnostic challenge to JIA TMJ involvement.…”

Magnetic Resonance Imaging of Temporomandibular Joint

“…The disk consists of anterior and posterior bands and a thin intermediate zone between the mandibular condyle and the articular eminence of the temporal bone to accommodate the gliding and hinging actions. 28 In this study, all morphometric measurements were carried out on the central section of the sagittal oblique images in closed mouth position. The morphometric measurement procedures used are described previously.…”

Evaluation of the relationships between contrast-enhanced magnetic resonance characteristics and joint pain in patients with temporomandibular disorders

“…In each portion, the mean peak-SI ratios in the painful TMJ group are significantly higher than those in the pain-free TMJ group. **p \ 0.01, Scheffe's F test authors have reported that TMJ pain is significantly associated with abnormal positional changes of the disk, and that the pain is frequently higher in patients with ADD WOR [38][39][40][41][42]. Excess disk displacement has been regarded as the main causal factor for the development of abnormal mechanical stress and subsequent inflammatory changes within the posterior disk attachment and articular capsule [43].…”

“…In the synovial membrane tissue of the posterior disk attachment region and the TMJ capsule, more highly innervated and inflamed tissues are sources and causes of greater pain [58]. It has been reported that ADD WOR may produce more mechanical stress and stretch on the posterior disk attachment than ADD WR during the mouthopening movement, causing more painful TMDs [42]. Loading of the posterior disk attachment is also regarded as a cause of pain when it is positioned between the articular surfaces of the mandibular fossa, articular eminence, and mandibular head.…”
