目的：目的是评估骨关节病（OA）的患病率在颞下颌关节（TMJ）的样本中的老年人使用对比剂增强MRI。方法：30例患者（73-75岁）从一个代表性的样本，并进行了临床检查。使用钆增强MR图像评估髁状突的形状，由两名独立的评估者进行评估。统计学评估采用描述性统计，卡方2检验和kappa statistics.Results：评分者之间的协议是极好的关于存在/不存在OA（kappa = 0.8）。仅1例受试者报告TMJ疼痛。所有受试者均未听到细微和/或粗糙捻发音。MRI显示70%的患者至少一侧颞下颌关节有骨性关节炎的征象。结论：钆增强MRI显示颞下颌关节骨性关节炎在老年人中较常见（70%），但临床症状的发生率很低。Dentomaxillofacial Radiology（2010）39，231-234. doi：10.1259/dmfr/16270943
Objectives: The aim was to assess the prevalence of osteoarthrosis (OA) in the temporomandibular joint (TMJ) in a sample of older people by use of contrast agent-enhanced MRI.Methods: 30 patients (73-75 years old) were drawn from a representative sample and were examined clinically. The shape of the condyle was assessed using gadolinium-enhanced MR images, which were evaluated by two independent raters. Statistical assessment was performed by using descriptive statistics, the chi 2 test and kappa statistics.Results: Agreement between raters was excellent with respect to the presence/absence of OA (kappa = 0.8). Only one subject reported pain in a TMJ. Fine and/or coarse crepitus was not heard in any subject. MRI showed that 70% displayed signs of OA in at least one TMJ. There were no gender-related differences in the prevalence of OA (P > 0.05).Conclusion: Gadolinium-enhanced MRI showed that OA of the TMJ is common in older people (70%), although the prevalence of clinical signs of OA is very low.
