“…Hypersignal in articular compartments, which indicates joint effusion, is relatively easy to detect in T2 weighted images. The reproducibility of this disorder was hereby substantial (κ = 0.63 for 0.5T images, and 0.70 for 1.5T images), similar to the value obtained by Ahmad et al 33 (2009) (κ = 0.64), but lower than that reported by Salé et al 28 (2014) (κ = 0.95) and Roh et al 10 (2012) (κ = 0.85).…”

“…Disc displacement is related to other degenerative disorders (e.g. ; disc shape change, condyle change, joint effusion, and condylar mobility), and the most severe changes are strongly linked to anterior disc displacement without reduction (DDWR) [8][9][10][11][12][13][14][15] . Even though MRI is considered appropriate to examine the TMJ, research has reported discrepancies between MRI-based and clinical diagnoses 1,[16][17][18][19][20][21][22] .…”

“…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].…”

Objectives To evaluate the correlations between temporomandibular joint (TMJ) pain and both conventional and gadolinium-enhanced magnetic resonance (MR) imaging characteristics in patients with temporomandibular disorders (TMDs). Methods T1-weighted, T2-weighted, and fat-suppressed contrast-enhanced T1-weighted MR imaging were performed in 80 TMD patients with the main complaint of TMJ pain. A kappa statistical analysis was performed to calculate the interobserver agreement between two of three radiologists. The relationships between TMJ pain and various MR findings were analyzed by multiple comparison test, Spearman's rank correlation test, Chi-square test, Student's t test, and multivariate logistic regression analysis. Results Significant correlations were observed between anterior disk displacement without reduction, joint effusion, and TMJ pain (p \ 0.01). The degree of contrast enhancement of the posterior disk attachment was correlated with the severity of TMJ pain, especially spontaneous pain (r = 0.725, p \ 0.01), while no correlation was observed in the masticatory muscle pain group. The correlation tended to be higher in the latero-central portions than in the medial portion of the mandibular condyle, although no significant difference was seen. Conclusions It has been suggested that fat-suppressed contrast-enhanced MR imaging techniques facilitate better understanding of the sources of TMJ pain, but not masticatory muscle pain, and could reflect TMJ synovial inflammation. The severity of TMJ pain was closely correlated with the degree of contrast enhancement. The above-mentioned correlation had a tendency to be higher in the latero-central portions of the mandibular condyle.

“…Wikes stages are determined by the placement and morphology of the articular disc and the bone destruction of hip process shown in TMJ MRI 7) . TMJ MRI is the gold standard in the diagnosis of TMJ [8][9][10] . The anabolism and formation of the bone were caused by the hpofunction of ovary and the decline of estrogen as for the postmenopausal women.…”

The purpose of this study was to investigate the relationship between the bone mineral density and the contents of osteocalcin calcium and phosphorus in serum with temporomandibular joint osteoarthrosis (TMJOA). The mineral densities of lumbar and neck of femur research groups, including the case group and the control group, were compared. The contents of osteocalcin calcium and phosphorus in serum were also measured and evaluated. The results showed that the mean bone mineral density of the case group (TMJOA group) was lower than that of the control group (healthy control). However, a statistical difference was not reflected. The mineral density of the neck of femur of the case group is lower than that of the controlled group obviously, suggesting that mineral density of the femur was related with TMJOA. It was presumed that the bone mineral density of the femur neck might have relationship with TMJOA. The level of osteocalcin in serum of the case group was significantly lower than that of the control group. Thus it is presumed that osteocalcin had a relationship with TMJOA. The results showed that the capability of bone transformation and formation in TMJOA were all decreased. No relationship was found between calcium phosphorus in serum and TMJOA.
