The aim of this study is to assess the perception of female students about the type of smile arc as well as their outlook about different parameters of esthetics.
A study was conducted among female students of King Khalid University, Abha, Saudi Arabia. One section of the questionnaire contained pictures having three types of smile arc wherein the respondents had to select any response ranging from 1 to 4 (1 for beautiful, 2 for good, 3 for average, and 4 for poor); besides it included 12 questions regarding the viewpoints of respondents about their smile and dental esthetics. The collected data were analyzed using the statistical package for social services version 16.0 (SPSS Inc., Chicago, IL, USA, 2001).
The dental students accounted for least mean score of 1.807 ± 0.8174 for consonant smile arc while it was 2.692 ± 0.8053 and 2.235 ± 0.9074 for information technology (IT) and medical students, respectively. When the individuals were asked whether they had a pleasant smile or not; only 53.8% of the dental students, 76.9% of the IT students, and 66.7% of the medical students responded positively.
It was concluded that most of the female dental students were able to identify the consonant smile arc as being more beautiful than the flat and reverse smile arcs whereas lesser medical and IT students could perceive the smile arcs in the same manner. It was also observed that almost all the study participants were quite conscious about their smile attractiveness and dental esthetics.
本研究旨在评估女学生对微笑弧度类型的认知以及她们对不同美学参数的看法。
在沙特阿拉伯阿卜哈的阿卜杜勒-阿齐兹国王大学的女学生中开展了一项研究。问卷的一部分包含有三种微笑弧度类型的图片，受访者必须从1到4中选择任何一个答案（1代表美丽，2代表良好，3代表一般，4代表差）；此外，问卷还包括12个关于受访者对自己的笑容和牙齿美学观点的问题。使用社会科学统计软件包第16版（SPSS公司，美国伊利诺伊州芝加哥，2001年）对收集到的数据进行分析。
牙医学专业学生对协调型微笑弧度的平均得分最低，为1.807±0.8174，而信息技术（IT）专业学生和医学专业学生的平均得分分别为2.692±0.8053和2.235±0.9074。当被问及她们是否有令人愉悦的笑容时，只有53.8%的牙医学专业学生、76.9%的IT专业学生和66.7%的医学专业学生给出了肯定回答。
得出的结论是，大多数女牙医学专业学生能够识别出协调型微笑弧度比平坦型和反转型微笑弧度更美观，而较少的医学专业和IT专业学生能以同样的方式感知微笑弧度。还观察到，几乎所有的研究参与者都非常在意自己笑容的吸引力和牙齿美学。
