Abstract
BackgroundThis study was to evaluate the diagnostic significance of Magnetic Resonance Imaging (MRI) in distinguishing temporomandibular disorders (TMD).MethodsA total of 684 patients with TMD were included in the study. Diagnosis for TMD was conducted according to the international criteria. Two professional radiologists were selected for professional training, and the Kappa values were compared for the diagnosis results to determine the consistency of the diagnosis. Then MRI images of these 684 patients were analyzed and the diagnosis results were obtained.ResultsMRI can be used for the diagnosis of TMD. There were significantly more females (518 cases) than males (166 cases) with TMD; Disc displacement with/without reduction is more common in the youth group, with the majority aged 20–30 years. The highest incidence of temporomandibular joint osteoarthrosis is in the 60-year-old age group, followed by the 70-year-old age group.ConclusionsBilateral temporomandibular joint MRI can clearly show their changes; there are significantly more female with TMD than male; osteoarthritis has a significant correlation with age.
Highlights
This study was to evaluate the diagnostic significance of Magnetic Resonance Imaging (MRI) in distinguishing temporomandibular disorders (TMD)
Temporomandibular joint (TMJ) is a bilateral linkage joint consisting of the upper temporal fossa and joint nodule, the lower mandibular condyle, the articular disc between the two, and the joint capsule and the ligaments inside and outside the capsule
Bilateral temporomandibular joint MRI has been gradually applied in clinical practice and showed high clinical application value
Summary
This study was to evaluate the diagnostic significance of Magnetic Resonance Imaging (MRI) in distinguishing temporomandibular disorders (TMD). Cong et al BMC Oral Health (2021) 21:481 assistance of imaging examination. X-ray and CT scan are commonly used auxiliary imaging examinations for the diagnosis of TMD. With the development of imaging technology, the application of magnetic resonance imaging (MRI) in the diagnosis of temporomandibular disorders (TMD) has become more and more mature. MRI can show the condition of TMJ well, and is an important means of examination and evaluation of TMD [3, 4]. We retrospectively analyzed the MRI results of 684 patients with TMDs in our hospital, and evaluated its value in assisting the diagnosis of TMD
