A rapidly increasing number of mandibular condylar fractures and some complications related to injuries of temporomandibular elements make this study important. Intra-articular disorders lead to secondary pathological findings such as osteoarthritis, deforming osteoarthrosis, and temporomandibular joint ankylosis that limits mouth opening, mastication, swallowing, breathing, and decreased/lost working capacity or disability. Early diagnosis of intra-articular disorders can prevent from long-lasting functional complications caused by temporomandibular joint injuries. This study was performed for the purpose of early detection and investigation of organic pathological changes in the cartilaginous and osseous tissues of the temporomandibular joint caused by traumatic fractures of the mandibular condyle. Twenty patients underwent a general clinical examination, magnetic resonance imaging (MRI), and immune-enzyme testing for biochemical markers of connective tissue injury (pyridinoline and deoxypyridinoline) in urine. Disk dislocation, deformation, adhesion, perforation or squeeze, tension or disruption of ligaments, and injury of articular surfaces are among complications of mandibular fractures that can be revealed on MRI. As regards biochemical findings, we revealed a sharp rise in the levels of pyridinoline and deoxypyridinoline before treatment and a lack of stabilization within 21 days of treatment.

Conventional and modern methods of radiological imaging are often used in the diagnosis of temporomandibular joint disorders, and the CT technique is particularly characterized by an excellent visualization of bony structures. The aim of the study was to show the importance and role of CT in the evaluation of TMJ bone structures in both patients with articular disc displacement and in a group of healthy subjects. Both study groups were assessed with the use of the transverse plane. Herein, multi-slice spiral computed tomography was performed in 47 subjects. These individuals were qualified for CT by way of magnetic resonance imaging, due to their being diagnosed with a displacement of their temporomandibular joint disc. The product of our study is presented as a set of tables. These are comparisons of radiological parameters based on the shape, size and location of the mandibular head, in the examined patients, in a control group, and with regard to sex. The results of our work indicate that CT can be successfully used in the imaging of TMJ bone structures, specifically, the condylar process of the mandibular head and the joint socket. However, statistically significant differences of the utilized parameters between patients with articular disc displacement and controls, warrant further analysis of this issue.

The prevalence of temporomandibular disorder (TMD) in the general population is difficult to identify. Depending on the source, values range from 3% to 48.9%. These large discrepancies occur because of two main reasons. The first one is connected with the evolution of the definition and diagnostic criteria of TMD, while the second one concerns the use of different diagnostic tools, protocols, etc. Temporomandibular joint (TMJ) diagnosis is both quantitative and qualitative. Quantitative measurements used in the field of scientific research are highly accurate motion capture systems used for kinematic analysis, while an electronic caliper is applied in a clinical setting. MRI seems optimal in TMJ disc and its dysfunction imaging. In more difficult cases, ultrasound imaging can be used. On the other hand, CT is the best examination for joint imaging. In recent years, qualitative measurements have been dominated by vibroarthrography (VAG), which shows good diagnostic value. Research Diagnostic Criteria for Temporomandibular Joint Disorders (RDC/TMD) is the most complex systematized diagnostic tool for TMD. The proposed procedure allows us to differentiate a real TMJ dysfunction from other systemic problems that can manifest themselves in this region of TMJ, such as depression, chronic pain or psychosomatic disorders. RDC/TMD are constantly evaluated and modified in terms of their diagnostic or clinical value by experts associated in the International RDC-TMD Consortium. Currently it is the best tool available for TMD diagnostics. The RDC/TMD questionnaire was translated into Polish, culturally adapted and officially approved by the Consortium. The aim of the study is to review selected TMD diagnostic tools and to assess their diagnostic value.
