Abstract
Temporomandibular joint disorders are characterized by many symptoms as pain, joint sounds, limited jaw opening, impaired jaw movement and less specific symptoms may happen as ear pain, neck pain and headache. Pain is the most chief complaint of patients with TMD.
Diagnostic imaging as CT or MRI play an important role to evaluate TMJ characteristics. MRI is a non-invasive diagnostic procedure that is considered to be the gold standard for TMJ imaging. Hence, MRI is recommended to evaluate TMD as internal derangement in addition to joint effusion, bone marrow edema and osteoarthritis.
Therefore, the aim of this study was to review current literature in an attempt to find correlation between TMD pain and MRI.
A systematic review was performed, by searching PubMed, Scopus and Web of Science electronic databases, following the PRISMA guidelines, for articles reporting TMJ pain and MRI imaging.
Application of the pre-set inclusion selection criteria throughout the screening process, yielded 21 articles. Raw data of articles were ejected and compared.
The mean ages of patient were 39.7±17.1 years and the gender of the patient is more incident in female predilection with percentage up to 81% and 19% in male.
Internal derangement was accounted on all 21 papers; 70% of patients have signs of ID (32% DDWR, 38% DDWOR) and 30% have normal disc position.
Osteoarthritis was reported in 9 articles as presence of osteoarthritis in 61% of joints and absent in 39% of joints.
Temporomandibular joint effusion was described in 8 articles; joint effusion was present of in 55% of joints and absent in 45% of joints.
Condylar bone changes were reported in 4 studies; 59% of the condyles were normal, 41% of the condyles had bony changes (12.5% flattening, 5% erosion, 12.4% osteophyte, 0.5% pseudocyst and 10.7% combination).
Bone marrow edema was reported in 3 articles only as presence of edema in 18.3% of joints and 81.7% of these studies are absence of edema.
