The purpose of this survey was to investigate the symptoms of temporomandibular joint disorders (TMD) in orthodontic patients and to define the relationships between symptoms and malocclusion and/or orthodontic treatment. The subjects were 532 patients, 6 to 38 year old Japanese, in the orthodontic department of Tokyo Dental College Hospital. They were examined for past or recent TMJ sounds, pain in the TMJ area, and abnormal jaw movements. The prevalence of TMJ symptoms was 33.8%. Sex differences were not statistically significant. The prevalence of TMD symptoms increased with age. TMD symptoms in young orthodontic patients (6-18 years old) were more common than in untreated subjects. Posterior crossbite and open bite patients had a high prevalence of symptoms.
本次调查的目的是研究正畸患者颞下颌关节紊乱病（TMD）的症状，并明确症状与错牙合畸形和/或正畸治疗之间的关系。研究对象为东京齿科大学医院正畸科的532例患者，年龄在6至38岁之间，均为日本人。对他们进行了既往或近期颞下颌关节弹响、颞下颌关节区域疼痛以及异常下颌运动的检查。颞下颌关节症状的患病率为33.8%。性别差异无统计学意义。TMD症状的患病率随年龄增长而增加。年轻正畸患者（6 - 18岁）的TMD症状比未经治疗的受试者更为常见。后牙反合和开牙合患者的症状患病率较高。
