Abstract


 

Background: Incomplete understanding of the anatomy of the temporomandibular joint (TMJ), its function and physiological changes, has led to diagnostic mistakes. Aim: We aimed to evaluate the position and bone changes of condyle using cone beam computed tomography (CBCT). Conclusion: Twenty-eight patients who had CBCT images of TMJ joints of both sides and had referred with signs of temporomandibular disorder to a private radiology center in Mashhad were enrolled. The location of condyle in the joint socket in closed mouth position in maximum intercuspation based on measurements of the superior, posterior, and anterior spaces of the joint, and bone changes of the condyle were studied. Of the 28 patients, most (89.3%) were female. The horizontal dimension of the CBCT images of 2.3% of patients was in the normal range and 97.7% were abnormal. The condyle’s position in the vertical dimension was normal in 40.9% of patients and abnormal in 59.1%. The most prevalent position of the condyle in horizontal dimension was the posterior position (79.5%). Increased superior joint space was the most prevalent position of the condyle in vertical dimension (54.5%). At least one type of bone changes was seen in 67.9% of patients. In evaluating condylar bone changes the frequency of flattening, erosion, osteophyte, sclerosis, absorption, and Ely cyst was 46.6%, 25%, 14.3%, 7.1%, 5.3%, and 3.6%, respectively. Clinical Significance: The most prevalent condyle position in horizontal dimension was posterior. In evaluation of bone changes of condyle, the highest frequency was related to flattening and the lowest was Ely cyst.
