%X <B>BACKGROUND: </B>The aim of this study was to evaluate whether degenerative bone changes in the mandibular condyle on cone beam computed tomography images are associated with the Eichner index.<BR><B>METHODS: </B>336 cone beam computed tomography images condyle images of 168 patients were analyzed for degenerative bone changes. These changes were named as condyle flattening, osteophytes, erosions, subchondral sclerosis, generalized sclerosis and subchondral cysts. The edentulous status of the patients was classified as group A-B-C and subtypes according to the Eichner index. Categorical variables were evaluated with chi-square test and p < 0.05 was considered statistically significant.<BR><B>RESULTS: </B>According to the results of the study, the most common degenerative condyle change was flattening of the condyle. Among the Eichner index groups, the most common group was A and the least common group was C. Condyle changes on the right and left sides were most commonly observed in group A patients. The statistically significant majority of patients with right-sided condyle flattening and erosion were in group C. No significant difference was found between all other condyle changes and Eichner index groups. There was no significant relationship between Eichner index and gender.<BR><B>CONCLUSIONS: </B>Degenerative bone changes (flattening and erosion of the condyle) in the condyle region were more common in group C patients with more tooth loss. There is a significant relationship between condyle changes and posterior toothlessness.
