“…Temporomandibular JE has been suggested to be a surrogate for an inflammatory process and used as an indicator for pharmacological and surgical intervention (3, 6, 24, 25). It has been proposed that JE may activate or sensitize nociceptive afferent neurons within the joint (3, 24), as well as, result in increased articular pressure, which may cause mechanical trauma.…”

“…It has been proposed that JE may activate or sensitize nociceptive afferent neurons within the joint (3, 24), as well as, result in increased articular pressure, which may cause mechanical trauma. Together this would result in induction of other inflammatory mediators and TMJ-pain (6, 25).…”

“…Magnetic resonance imaging (MRI) is a non-invasive imaging modality that has shown to have excellent reliability and validity for analyzing soft tissues and fluids within the TMJ complex. It can also be used for the assessment of hard tissues; however, the reliability has been shown to be poor (3–5). …”

“…Furthermore, it has often been used as an indication for pharmacological and surgical intervention (6–11). Radiologically, it has been associated with degenerative joint disease (3, 4, 12). In addition, it has been suggested that JE may be associated with morphological and positional soft tissue changes, such as disc deformity or disc displacement with and without reduction (11–14).…”

“…Literature on JE and its association with clinical and radiological variables is inconsistent and is characterized by multiple methodological limitations such as the absence of control group (3, 11, 15); non-standardized examination of the TMJ (11, 15); presence of confounding factors, such as inclusion of participants with degenerative joint disease (DJD) (16), or participants on anti-inflammatory medications (17, 18); or lack of information regarding examiner or radiologist reliability (7, 9–11, 15, 19). …”

Purpose Literature on joint effusion (JE) and its association with clinical and radiological variables in patients with temporomandibular disorders (TMD) is inconsistent and is characterized by multiple methodological limitations. The primary aim of this investigation was to evaluate the association between magnetic resonance imaging (MRI) identified JE and TMJ arthralgia. The secondary aim of this investigation was to determine the association between JE and other clinical and MRI identified soft tissue characteristics. Methods A retrospective cohort study was conducted. Clinical and soft-tissue imaging assessments were carried out following the Diagnostic Criteria for Temporomandibular Disorders guidelines. The dependent variable was JE and primary independent variable was arthralgia. The secondary independent variables comprised of TMJ-pain associated characteristics, and magnetic resonance identified variables. When applicable either Pearson Chi-square or T-test was used to determine the statistical associations between JE and clinical characteristics, and between JE and MR identified variables. Furthermore, generalized estimating equations (GEE) model was conducted to determine which of the independent clinical and MR identified variables were associated with JE. Results Data for 158 participants, representing 312 joints was extracted. The mean age of the female sample (59.4 %) was 31 ± 11.1 years and of the male sample (40.6 %) was 29.8 ± 9.7 years. No association was found between JE and arthralgia. However, statistically significant associations were found between JE and lateral disc rotation (p = .001) and between disc position in the coronal and sagittal planes (p = .001). The GEE model suggested that disc displacement with reduction (OR = 2.5) was statistically significant contributing factors for JE in the absence of DJD. Conclusion Results indicate that JE is associated with the position of the disc in sagittal plane. No association was found between JE and arthralgia, or TMJ-pain associated clinical characteristics in patients with TMD.
