“…Temporomandibular disorders refer to a group of disorders characterized by pain and tenderness in the TMJ, or the masticatory muscles, with limitation or deviated mouth opening and clicking sounds heard in the TMJ during mandibular function with pain in adjacent structures, and these do not interfere with growth or development and are not related to systemic diseases. (4) TMDs are associated with morphological and functional deformities and are the main source of orofacial pain of non-dental origin (5). Degenerative bone changes involving the bone structures of the temporomandibular joint (TMJ) such as attening, erosion, osteophytes, subchondral bone sclerosis and Ely cyst are commonly associated with TMDs.…”

Background and aim: The aim of this study is to evaluate the changes in the temporomandibular joint (TMJ) in patients with temporomandibular disorder (TMD) and the relationship between age, sex, and types of TMJ change using Cone Beam Computed Tomography (CBCT). Methods and material: CBCT records of 200 patients (123 women and 67 men) were retrieved and assessed. Right and left TMJs were evaluated separately, resulting in a total of 400 TMJs. The images were analyzed using On demand 3D Application The radiographic findings were classified as erosion, proliferative changes mainly, including flattening and osteophytes of the condyle, sclerosis, Ely cyst, hypoplasia and hyperplasia of the condyles, ankylosis, and joint cavity. Data analysis was performed using descriptive statistics, paired T-tests, and repeated measure ANOVA (Analysis of Variance) in SPSS Software. Results: The most prevalent types of condylar bony changes observed was osteophyte (63.5%) followed by flattening of the articular surface (42%), erosion (40 %), ankylosis (10%) and sclerosis (10%). 7.5% of joints showed hyperplastic condyles but only 2% showed hypoplasia. The least prevalent change observed was Ely Cyst (1%). Osteophyte was the most prevalent change observed in all age groups and both sexes except for men aged 31~50, where flattening was more frequent. A statistically significant difference was found between sex and prevalence of erosion in the age group of 10~30 (P = 0.001); as well as between sex and condylar hyperplasia in the same age group. Conclusion: Based on the findings of this research, the prevalence of bony changes of TMJ from highest to lowest is as follows: osteophyte, flattening of the articular surface, erosion, ankylosis, sclerosis, hyperplastic condyles, hypoplastic condyles and Ely Cyst. CBCT is an accurate 3 dimensional imaging modality for assessment of TMJ bony structures.
