目的探讨颞下颌关节紊乱病(TMD)患者相关疼痛和年龄、性别及骨关节病(OA)影像学改变的关系。方法1206例TMD患者根据年龄、性别、是否疼痛及影像学改变分组;计算颅下颌关节紊乱指数(CMI)并进行统计学分析。结果TMD相关疼痛女性多见,45岁以下各年龄组间CMI差异有统计学意义,女性OA影像学改变发生率高于男性(P<0·001)。结论TMD相关疼痛和OA影像学改变易发生于女性,临床病例中16~30岁女性患者最多,并存在TMD相关疼痛和OA影像学改变。
Objective To investigate the relationship between pain and age, gender and osteoarthrosis (OA) in patients with temporomandibular disorder (TMD). Methods A total of 1206 patients with TMD were divided into groups according to their age, sex, pain and imaging changes. Cranial mandibular joint disorder index (CMI) was calculated and statistically analyzed. Results Female patients with TMD-related pain were more common. There was significant difference in CMI between different age groups under 45 years of age. The incidence of OA in female patients was higher than that of male (P <0.001). Conclusion TMD-related pain and OA imaging changes occur easily in women. Most of the patients aged from 16 to 30 years in clinical cases are suffering from TMD-related pain and OA imaging changes.
