Abstract

The aim of this study was to assess on videographs the intra- and inter-rater reproducibility of the Smile Esthetic Index (SEI) that has been previously validated on photographs. Smile videographs were obtained using a smartphone associated with the Smile Lite MDP mounted on a tripod. They were then randomized and evaluated twice consecutively at a 1-week interval by three periodontists according to the SEI based on 10 variables. Cohen’s Kappa and Fleiss’ Kappa tests were performed to measure intra- and inter-rater agreement. Sixty-five smile videographs of 24 men and 41 women (mean age 33 ± 11.3 years) were scored. A mean intra-rater agreement of 0.68 (0.64–0.73) was obtained, representing substantial agreement. The inter-rater agreement calculated for each variable ranged from 0.31 for the variable “absence of visible excessive gingiva” to 0.90 for the variable “absence of diastema and/or missing inter-dental papilla.” Within the limits of this study, we have demonstrated that it was possible to use videographs to reproducibly evaluate an aesthetic score (SEI) previously validated on photographs.
录像作品的微笑美学评价:评价者内部与评价者之间的一致性研究
这项研究的目的是评估在录像中,微笑审美指数(SEI)的内部和内部的再现性,这已经在照片上得到了验证。微笑视频是使用安装在三脚架上的与微笑Lite MDP相关的智能手机获得的。然后由三名牙周病医生根据基于10个变量的SEI,每隔一周对他们进行连续两次随机评估。采用Cohen’s Kappa和Fleiss’s Kappa检验来衡量评分者内部和内部的一致性。对65组微笑录像进行评分,男性24人,女性41人(平均年龄33±11.3岁)。获得了0.68(0.64-0.73)的平均评分一致性,代表了实质性的一致性。每个变量的评分间一致性从0.31(“没有可见的过度牙龈”)到0.90(“没有隔膜和/或缺失牙间乳头”)不等。在本研究的范围内,我们已经证明可以使用视频来重复评估先前在照片上验证的美学评分(SEI)。
