Introduction: The temporomandibular joint (TMJ) is a ginglymoarthrodial synovial joint. TMDs(tempomandibular disorders ) encompass a range of disorders affecting the muscular, soft tissue, and bony components of the TMJ, with clinical symptoms such as pain, clicking, limited mandibular movement, and muscle tenderness.
Diagnosis of TMD involves history taking, clinical examination, and imaging, with radiographic examination being crucial for planning appropriate treatment. Modalities such as panoramic radiography, conventional tomography, and computed tomography (CT) are commonly used.
Cone beam computed tomography (CBCT) is preferred for TMJ imaging due to its dose-sparing benefits, effectiveness, and shorter scanning time compared to conventional CT.Morphological changes in the TMJ, including condyle morphology, joint space, and articular eminence, are closely linked to TMD etiology.
Joint spaces are categorized as increased, normal, reduced, or absent. Reduced joint space is commonly associated with degenerative arthritis and age-related changes.
Materials and Methods: This study includes 30 CBCT scans images, images were obtained from the patients who underwent CBCT examination for complain in TMJ area were considered as ( CASE group ) and in which CBCT image was taken for any other reason in which TMJ area was covered considered as (Control group )based on RDC criteria. The joint space was measured after adjusting the axial view at maximum convexity of condyle on both sides in TMJ view present in software at three positions i.e superior,medial, lateral.
Results: shows the comparison of joint space thickness between TMD and non-TMD patients for different positions.T test is used for comparison (p value >0.05)the results retain the null hypothesis and there is no significant difference between the group
Conclusion: The joint space measurement can be used as a method for assessing the TMDs with more samples and considering other factors.
