Background
This study aimed to evaluate the relationships between magnetic resonance imaging (MRI) findings (such as condylar degeneration, disc displacement, joint effusion and disc deformity) and clinical symptoms in patients with temporomandibular joint disorders (TMDs).
Methods
A total of 54 patients (108 temporomandibular joints (TMJs)) were included. Clinical evaluations assessed joint pain, joint sounds, mouth opening limitations, deviation/deflection and locking. MRI scans were analyzed for condylar degeneration, disc displacement (disc displacement with reduction (DDWR) or disc displacement without reduction (DDWOR)), joint effusion, and disc morphology. Statistical analyses included chi-square tests/Fisher's exact tests for categorical variables. A p value < 0.05 was considered to be statistically significant.
Results
DDWR and DDWOR were significantly associated with joint pain (p = 0.044) and sounds (p = 0.032). Joint effusion demonstrated no clear correlation with clinical symptoms. Condylar degeneration was frequently observed but had limited clinical impact, except for a reduction in joint sounds (p = 0.03). Moreover, disc deformity was significantly correlated with condylar degeneration and joint effusion (p < 0.001).
Conclusions
MRI findings provide valuable insights into the structural changes observed in TMDs. Although disc displacement is strongly linked to pain and joint sounds, condylar degeneration and effusion exhibit more complex relationships with clinical symptoms.
