What is the Temporomandibular Joint?The temporomandibular joint (TMJ) is a typicalsliding "ball and socket" which has a discsandwiched between it. The TMJ is used manythousands of times a day in moving the jaw,biting and chewing, talking, yawning, etc. It isone of the most frequently used of all the jointsin the body.http://www.medicinenet.com/temporomandibular_joint__disorder/page1.htm#1whatis

Prospective Study of TMJ Arthritis in JIA• Determine the point prevalence of TMJ arthritis at disease onset in children with JIA using MRI and ultrasound • Subaim: comparative study of MRI versus ultrasound for diagnosing TMJ arthritis• Development of a screening protocol to predict those children with JIA at greatest risk for developing TMJ arthritis • Using demographics, serologies, physical examination, CHAQ, and questionnaire on TMJ functionality/pain
Inclusion Criteria:• Meet the diagnostic criteria for JIA• Able to complete study within 8 weeks of diagnosis Exclusion Criteria:• Inability to undergo MRI due to metal implants, braces, pacemakers
MRI Findings• All the patients with effusion AND enhancement AND condylar flattening had polyarticular disease.• All the patients with effusion AND enhancement but NO condylar flattening had oligoarticular disease.• No other correlations with MRI pattern and age/ duration of disease/ JIA subtype/ CHAQ score/ serologies.

TMJ Arthritis Detection(Dis)agreement by MRI & US
Summary of Acute vs Chronic Findings• Acute: presence of effusion or enhancement – Seen in all but two patients (83% bilateral)• Chronic: presence of condylar flattening – Seen in 69% by MRI, most with Poly JIA, 26% by US• Concordance of MRI and US: – 0% agreement in detection of effusions – 22% agreement in detection of condylar flattening• Length of disease, CHAQ score, and erythrocyte sedimentation rate (ESR) did NOT correlate significantly with either chronicity or acuity on MRI.
TMJ Arthritis: Prevalence, Diagnosis, and Predictors of Active Disease • What we’ve learned: – Prevalence of TMJ arthritis is quite high – Unable to establish predictors of active disease at this time given the high prevalence – MRI appears much more sensitive than US in detecting early inflammatory changes in the TMJ, especially given operatorPam Weiss, MD dependence of US Weiss, et al. Arthritis Rheum. 2008;58:1189-96.

Questions that Arise:• Since bilateral enhancement is so common, could it be a normal post-contrast finding?• Could condylar flattening by itself, or with enhancement, be a normal finding?• If the above is true: 50% of the kids currently found to have abnormal TMJs by MRI could be normal.• Therefore: Important to have controls, especially to help make treatment decisions.

What do we do for TMJ arthritisnot responsive to IA-steroids?• Many have already failed repeated (2 or more) IA-steroid injections.• The vast majority are already on high dose, aggressive systemic arthritis therapy (e.g. methotrexate and anti-TNF agents at high doses).
Intra-articular anti-TNF to treat TMJ arthritis• Scand J Rheumatol. 2008 Mar-Apr;37(2):155-7. Alstergren• Successful treatment with multiple intra-articular injections of infliximab in a patient with psoriatic arthritis.• Alstergren P, Larsson PT, Kopp S.• Department of Clinical Oral Physiology, Institute of Odontology, Karolinska Institutet, Huddinge, Sweden. firstname.lastname@example.org• Abstract• This case report presents the clinical and radiographic course of temporomandibular joint (TMJ) involvement in a patient with severe TMJ symptoms from psoriatic arthritis (PsA) resistant to both systemic infliximab and intra-articular glucocorticoid and who therefore received multiple intra- articular infliximab injections for 36 weeks. TMJ symptoms improved after the first bilateral intra-articular infliximab injections but even more so after the second injections. The considerable improvement remained for the 36 weeks studied. Bilateral computerized tomography showed no progression in radiographic changes during the treatment. No adverse reaction was observed from the intra-articular injections.

Do non-JIA children with otherrheumatic diseases develop TMJ arthritis?• Many other pediatric rheumatic disorders are associated with arthritis (SLE, myositis, sarcoidosis, Sjogren, MCTD, etc.).• Some children with the above disorders have PE findings or complaints suggestive of TMJ arthritis.

Things to Consider• 50-75% of children with JIA develop TMJ arthritis.• All subtypes of JIA develop TMJ arthritis.• TMJ arthritis is frequently asymptomatic.• Inflammation of the TMJ leads to growth plate arrest (micrognathia).• MRI is the most sensitive modality for detecting TMJ arthritis.• Intraarticular corticosteroid injection is effective treatment for TMJ arthritis in JIA.• TMJ arthritis can develop while being treated with methotrexate plus a TNF inhibitor.• TMJ arthritis may be active while other joints are in remission.• Intraarticular infliximab injection treats refractory TMJ arthritis.• Children with sarcoidosis, Sjogren, JDMS, and MCTD can develop destructive TMJ arthritis.
