目的

分析我国颞下颌关节紊乱病（TMD）患者的诊断分类情况。

方法

使用本课题组前期建立的颞下颌关节紊乱病研究诊断标准（RDC/TMD）中文版对TMD 患者进行调查，根据调查结果对TMD 患者进行诊断分类，包括第一组肌病类；第二组关节盘移位类；第三组关节痛、关节炎、关节病类。

结果

共有142 例TMD 患者完成调查，有效量表133 份，量表的完成率为93.7%，其中男38 例，女95 例，男女比例1 ∶2.5。 患者年龄高发于18 ～44 岁，67.7%的研究对象接受过大学文化教育，84.2%研究对象月收入在5000 元以下。 133 份有效量表中121 例符合RDC/TMD 轴Ⅰ分类，第一组患病率为16.5%；第二组左、右侧颞下颌关节患病率分别为37.2%和27.3%，以可复性盘前移位最常见；第三组左、右侧颞下颌关节患病率分别为43.0%和38.9%，以关节痛最常见。

结论

我国TMD 患者中以可复性盘前移位和关节痛最常见。

Objective

The study aimed to assess the distribution of temporomandibular disorders （TMD） sub-types in Chinese people seeking treatment for TMD.

Methods

Clinical data of the TMD patients were collected and analyzed by using the Research Diagnostic Criteria for TMD（RDC/TMD）. Three sub-types of TMD （Group 1， muscle disorders； Group 2， disc displacements and Group 3， arthralgia， arthritis， arthrosis） were measured.

Results

A total of 142 TMD patients were surveyed and examined clinically. There were 133 valid scales and 9 missed. In this study 38 men and 95 women with the ratio of 1 ∶2.5 were involved. Patients suffered from TMD were commonly found in the age between 18 and 44. 67.7% of TMD patients received college education， and 84.2% TMD patients' monthly income were below 5000 yuan. The results of the axis I diagnosis indicated that the prevalence of Group 1 was 16.5%. In Group 2， the incidence of disc displacement in the left temporomandibular joint was 37.2% and in the right 27.3%. The disc displacement with reduction was particularly common. The prevalence of Group 3 was 43.0% in the left temporomandibular joint and 38.9% in the right. The arthralgia was common in patients of this group.

Conclusions

Disc displacement with reduction and arthralgia were more common in these TMD patients.
