2种量表在评定青少年主观(牙合)美观程度中的应用

目的:采用视觉模拟量表(visualizedanaloguescale,VAS)和正畸治疗需要指数的美学量表(aestheticcompo鄄nent,AC)分别量化评定青少年的自身牙合美观程度,比较两者的评定效能及信度。应用SPSS11.0统计软件包进行相关分析。方法:随机抽取上海地区11～13岁青少年共302例(男148例,女154例),分别采用2种量表进行牙合美观程度的主观评价,同时由正畸医生进行牙合美观程度的客观评定。结果:Spearman相关检验显示,自评AC及VAS均与性别无关(P>0.05);VAS分值与主观牙合美观满意度显著相关(r=0.80,P=0.000),且与正畸医生的专业评定一致性较高;自评AC等级与主观牙合美观满意度无显著相关性(P=0.441)。结论:应用VAS量表评定青少年主观牙合美观程度的可信度较高且简单易用,适合定量分析,为今后量化评定主观正畸治疗需求提供了一种新方法。

Evaluations of self-perceived orthodontic treatment need using 2 different scales in adolescents

PURPOSE: To evaluate the self-perceived dental aesthetics through visualized analogue scale (VAS) and aesthetic component (AC) of index of orthodontic treatment (IOTN) among adolescents in Shanghai area. METHODS: The investigation was carried out among 302 students (148 boys and 144 girls) aged 11-13 years. Self-perception of the dental aesthetic appearance was evaluated through VAS and AC. Additionally, the objective dental aesthetics were scored by orthodontists using AC and the actual dental attractiveness satisfaction was determined by a simple question. The data was analyzed using SPSS11.0 software package for Spearman correlation analysis. RESULTS: Generally, no statistically significant sex differences were found in relation to the VAS score and SAC degree (P>0.05). No correlation was found between actual dental attractiveness satisfaction and self-perceived AC grade(r=0.04, P=0.441). However, statistically significant, positive, strong correlations were found between the actual dental attractiveness satisfaction and VAS score (r=0.80, P=0.000). And meaningful relation between the AC and VAS score was found. CONCLUSIONS: VAS showed high ability to predict the self-perceived dental aesthetics and act as a simple and useful tool, which can be used in further investigations.
