摘　　要：目的:使用牙美学指数评估青年人群的正畸需要,并分析牙外观自我评估值同牙美学指数分值之间的关系。方法:358名大学生参加了牙美学指数检查,同时每位被调查者使用视觉模拟量表对牙外观进行自我评估。对牙美学指数分值和牙外观自我评估进行简单线性相关分析,并基于牙美学指数分组对牙外观自我评估进行秩合检验。结果:37.7%的被调查对象牙美学指数分值≥31,属于需要正畸治疗人群。牙美学指数与牙外观自我评估间呈中度负相关(P<0.001),基于牙美学指数分组对牙外观自我评估进行秩合检验表明4组间得分差异有统计学意义(P<0.001)。结论:本样本中,37.7%的被调查对象需要正畸治疗;牙美学指数与牙外观自我评估呈反向关系。表明牙美学指数可用于青年人群口腔健康相关生活质量的相关研究。Objective： To evaluate the orthodontic treatment needs in Chinese young adults and the relationship between Dental Aesthetic Index （DAD and self-perceived dental appearance. Methods： This cross-section study included a convenience sample of 18.7 to 24. 1-year-old young adults. Traits of malocclusion were examined according to rules of Dental Aesthetic Index. Every subject was required to finish a visual analog scale to report their self--perceived dental appearance. The relationship between DAI and self-perceived dental appearance were evalua- ted through Pearson linear correlation and Kruskal-Wallis test. Results： 37.7% subjects were DAI≥ 31. Pearson r for DAI and self-perceived dental appearance was -0.61. Furthermore, the scores of self-perceived dental appearance were significantly reduced along with increasement of rank of DAI. Conclusion： 37.7% subjects were orthodontic treatment highly desirable. DAI and self-perceived dental appearance were significantly negative correlated, which meaned that DAI could be used in studies about malocclusion related quality of life.
