Abstract

OBJECTIVE: To assess the perception of buccal corridor width on smile esthetics by Orthodontic residents, General dentists and Laypersons. METHODOLOGY: A smile photograph was taken of an adult female. The image was modified to obtain five different buccal corridor widths and were assessed by different evaluators grouped into general dentist, orthodontic resident and laypersons who rated the attractiveness of each smile by means of a visual analog scale (VAS). Sample size was 97 participants to rate the picture. Non-probability purposive sampling was done The data was analyzed and mean and SD were calculated for the scores of rating. ANOVA and Tukey's post hoc test was applied to compare the different ratings of buccal corridors in three groups. The data of this cross sectional study was collected from general population belonging to different communities, general dentists and orthodontic residents of different dental colleges of Karachi, Pakistan from August 2019 to March 2020. RESULTS: There were 97 participants who responded to the images. Highest scores were obtained for Image 1 having buccal corridor width ratio of 16% followed by image no. 3 having buccal corridor width ratio of 10% and lowest scores were obtained for Image no. 6 having least buccal corridor widths ratio that is 34% followed by image no 5 having 26% buccal corridor widths. Among the groups of participants, the highest scores were given by laypersons for all images. Significant differences were observed between evaluation of groups of Orthodontic resident and layperson in most images. CONCLUSION: There was a remarkable influence of buccal corridor width on smile esthetics, with the 16% ratio group being rated as the most attractive by all three groups.

颊道宽度对微笑质量和美学的影响
目的:评价口腔正畸住院医师、普通牙医和门外汉对口腔走廊宽度对微笑美学的感知。方法:选取一名成年女性的微笑照片。对图像进行修改,获得五种不同的颊道宽度,并由不同的评估者进行评估,这些评估者分为普通牙医、正畸住院医生和非专业人员,他们通过视觉模拟量表(VAS)对每种微笑的吸引力进行评估。样本量为97名参与者对图片进行评分。进行非概率目的抽样,对数据进行分析,计算评分的均值和标准差。采用方差分析和Tukey事后检验比较三组患者颊道的不同评分。本横断面研究的数据收集自2019年8月至2020年3月巴基斯坦卡拉奇不同社区的普通人群、普通牙医和不同牙科学院的正畸住院医生。结果:有97名参与者对图像有反应。图像1得分最高,其颊道宽度比为16%,其次是图像1。3例口腔走廊宽度比为10%,影像号得分最低。6具有最小的颊走廊宽度比率为34%其次是图像5具有26%的颊走廊宽度。在参与者组中,外行人对所有图像的得分最高。正畸住院患者组与门外汉组在大多数图像上的评价存在显著差异。结论:颊道宽度对微笑美学有显著影响,比例为16%的组在三组中最具吸引力。关键词:颊廊,微笑,美学,吸引力
