Objective:
The purpose of this study was to investigate the correlation between articular eminence steepness and clinical dysfunction index (Di) in patients with temporomandibular joint dysfunction (TMD) using cone-beam computed tomography (CBCT).
Study Design:
In this study, CBCT images of 60 temporomandibular joints in 30 patients with TMD were evaluated. The eminence inclination values were measured on CBCT images. Patients were subdivided into 3 groups based on Helkimo's clinical Di. The data were analyzed using Spearman's rho correlation coefficient test.
Results:
The results of the present study did not confirm any significant differences in the values of articular eminence inclinations among the 3 groups (P value >.05).
Conclusion:
Based on the present study, there is no apparent relationship between the articular eminence inclination and the clinical Di in patients with TMD.
