The purpose of this study was 1) to compare condyle - fossa relationships in the temporomandibular joint (TMJ), and 2) to score condylar resorption by using a TMJ indexing system in patients with JIA and without JIA.
The present retrospective cross-sectional study included cone-beam computed tomography (CBCT) images obtained from the sagittal, coronal, and axial slices. In the multidisciplinary Pediatric Rheumatology Outpatient Clinic at The University of Alabama at Birmingham (UAB) children with JIA are also examined by a group of orthodontists working in the same institute from October 2018 to July 2019. The predictor variable consists of patients with JIA and without JIA. The primary outcome variables are the depth of the mandibular fossa, joint spaces, axial angles, medio-lateral width, and condyle resorption. Other study variables were age and sex. In this study, the measurements obtained from 2 different groups (with JIA and without JIA) are compared using a t-test, where Tukey is utilized to adjust for multiple comparisons. The left and right joints are analyzed separately as the paired t test conducted showed a significant difference between the 2 joints (P < .05).
The study was comprised of 34 patients diagnosed with JIA and 34 healthy subjects. The depth of the mandibular fossa, the anterior joint spaces, the axial angles, and the resorption index showed statistically significant differences between the JIA and healthy groups in both left and right sides (P < .05). However, there was no statistically significant difference in the posterior joint spaces and mediolateral width between JIA and healthy groups in both sides (P > .05).
The results of our study presented the destructive potential of juvenile idiopathic arthritis by using CBCT. CBCT scanning is a helpful tool in the evaluation of the radiographic result of TMJ.
本研究的目的是：1）比较颞下颌关节（TMJ）中髁突 - 关节窝的关系；2）使用TMJ索引系统对患有幼年特发性关节炎（JIA）和未患JIA的患者的髁突吸收情况进行评分。
本回顾性横断面研究纳入了从矢状面、冠状面和轴位切片获得的锥形束计算机断层扫描（CBCT）图像。2018年10月至2019年7月，在阿拉巴马大学伯明翰分校（UAB）的多学科儿科风湿病门诊，同一机构的一组正畸医生也对患有JIA的儿童进行了检查。预测变量包括患有JIA和未患JIA的患者。主要结局变量为下颌关节窝深度、关节间隙、轴角、内外宽度和髁突吸收情况。其他研究变量为年龄和性别。在本研究中，使用t检验比较从2个不同组（患有JIA和未患JIA）获得的测量值，其中使用Tukey方法进行多重比较调整。由于进行的配对t检验显示2个关节之间存在显著差异（P < 0.05），因此对左右关节分别进行分析。
该研究包括34例诊断为JIA的患者和34名健康受试者。下颌关节窝深度、前关节间隙、轴角和吸收指数在JIA组和健康组的左右两侧均显示出统计学上的显著差异（P < 0.05）。然而，JIA组和健康组两侧的后关节间隙和内外宽度在统计学上无显著差异（P > 0.05）。
我们的研究结果通过CBCT展示了幼年特发性关节炎的破坏潜力。CBCT扫描是评估TMJ影像学结果的有用工具。
