To compare the visual analogue scale (VAS) and the simplified Q-sort method used to investigate the highest level of agreement among dentists, orthodontists and laypeople when assessing smile and dental attractiveness.
An album containing 258 photos of 86 individuals with their lips at rest, a slight and broad smile, was assessed by 25 dentists (general clinicians and various specialties), 23 orthodontists and 27 laypeople with regard to smile and dental attractiveness. To this end, both VAS and simplified Q-sort method were used. Agreements were calculated by intraclass correlation coefficient (ICC).
For the single measurement between the VAS method and the simplified Q-sort method, all simplified Q-sort rates were higher in all groups. The simplified Q-sort method results ranged between 0.42 and 0.49 while those of the VAS method varied between 0.37 and 0.42. The simplified Q-sort method also presented higher mean measurement values (0.95 and 0.96) in comparison to VAS (0.94 and 0.95).
Both scales may be considered reliable for evaluating smile and dental attractiveness; however, the simplified Q-Sort method presented slightly higher values than the VAS method.
比较视觉模拟评分法（VAS）和简化Q分类法，以研究牙医、正畸医生和外行人在评估笑容和牙齿美观度时的最高一致水平。
一本包含86名个体在嘴唇放松、轻微微笑和灿烂微笑状态下的258张照片的相册，由25名牙医（普通临床医生和各个专科医生）、23名正畸医生和27名外行人对笑容和牙齿美观度进行评估。为此，使用了VAS和简化Q分类法。通过组内相关系数（ICC）计算一致性。
对于VAS法和简化Q分类法之间的单次测量，所有组中简化Q分类法的所有比率均更高。简化Q分类法的结果在0.42至0.49之间，而VAS法的结果在0.37至0.42之间变化。与VAS（0.94和0.95）相比，简化Q分类法的平均测量值也更高（0.95和0.96）。
两种量表在评估笑容和牙齿美观度方面均可视为可靠；然而，简化Q分类法的值略高于VAS法。
