Prediction of TMJ arthralgia according to clinical diagnosis and MRI findings.

摘要: Purpose The aim of this study was to investigate the ability clinical and magnetic resonance imaging (MRI) diagnoses predict pain in temporomandibular joint (TMJ). Materials methods One hundred forty-nine patients were examined by 2 calibrated examiners strict accordance with Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). All who presented a defined RDC/TMD diagnosis included underwent bilateral coronal sagittal MRI TMJ. Two raters blinded interpreted scans TMJ pathology. results tested against according RDC/TMD, including pain-related disability psychosocial status, associations arthralgia using logistic regression analysis (GENMOD procedure, P Results MRI-depicted anatomic changes, such as effusions, disc displacement, osteoarthrosis, not significantly correlated presence However, significant relationship between on palpation masseter muscle origin (P = .0050) factors .0452) demonstrated. Conclusions Pain caused proximity lateral pole possible existence trigger points musculature may lead false-positive or false-negative arthralgia. Additionally, clinicians must consider aspects ideal treatment planning.
