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).
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.
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).
Based on the present study, there is no apparent relationship between the articular eminence inclination and the clinical Di in patients with TMD.
本研究旨在通过锥形束 CT（CBCT）研究颞下颌关节功能紊乱（TMD）患者关节结节陡峭度与临床功能障碍指数（Di）的相关性。
本研究共评估了 30 例 TMD 患者的 60 个颞下颌关节的 CBCT 图像。在 CBCT 图像上测量了关节结节倾斜值。根据 Helkimo 的临床 Di 将患者分为 3 组。使用 Spearman's rho 相关系数检验对数据进行分析。
本研究结果未证实 3 组之间关节结节倾斜值存在显著差异（P 值>.05）。
根据本研究，TMD 患者的关节结节倾斜度与临床 Di 之间似乎没有明显关系。
