调查患有或不患有颞下颌疾病 (TMD) 的韩国儿童和青少年骨关节炎变化和颞下颌关节 (TMJ) 髁突定位的患病率。该研究共纳入了101名无症状和181名有症状的10至18岁儿童和青少年。使用锥形束计算机断层扫描 (CBCT) 图像评估骨关节炎的变化，例如扁平、硬化、骨赘或侵蚀，以及髁突的矢状旁定位。有症状的青少年骨关节炎变化的总体患病率 (26.8%) 高于无症状青少年 (9.9%) (p<0.05)。在有症状组中，男性（33.3%）的频率高于女性（23.0%）（p<0.05）。糜烂是有症状组最常见的变化（15.6%），而硬化是无症状组最常见的变化（5.4%）。在有症状的组中，后髁位置更常见（p<0.05）。与没有颞下颌关节疼痛或张口受限的样本相比，糜烂在有颞下颌关节疼痛或张口受限的样本中更为常见（p<0.05）。这项研究表明，颞下颌关节骨关节炎改变在儿童和青少年中很常见，在有症状的患者中患病率要高得多。
To investigate the prevalence of osteoarthritic changes and condylar positioning of the temporomandibular joint (TMJ) in Korean children and adolescents with or without temporomandibular disorders (TMDs). A total of 101 asymptomatic and 181 symptomatic children and adolescents aged 10 to 18 years old were included in the study. Osteoarthritic changes such as flattening, sclerosis, osteophytes, or erosion, and the parasagittal positioning of the condyle were assessed using cone-beam computed tomography (CBCT) images. The overall prevalence of osteoarthritic changes was higher in symptomatic (26.8%) than in asymptomatic adolescents (9.9%) (p<0.05). In the symptomatic group, the frequency was higher in males (33.3%) than in females (23.0%) (p<0.05). Erosion was the most common change for the symptomatic group (15.6%), whereas sclerosis was the most common change for the asymptomatic group (5.4%). Posterior condylar position was more frequently observed in the symptomatic group (p<0.05). Erosion was more common in the samples with TMJ pain or mouth opening limitations as compared to those without them (p<0.05). This study showed that osteoarthritic changes in TMJ were common in children and adolescents, with a much higher prevalence in symptomatic patients.
