This study was designed to evaluate the buccal corridor in smile esthetics and to correlate it with underlying hard tissues.
Posed smiling frontal photographs, digital posterior-anterior (PA) cephalograms, and study models of 25 males and 25 females in age range of 18-25 years were taken. Photographs were evaluated for smile esthetics by eight orthodontists, eight plastic surgeons, eight beauticians and eight lay people to group them into three groups with least attractive, average and attractive smile and buccal corridor width was measured. Digital PA cephalograms were transferred on Nemo-tech software for frontal facial analysis. Intercanine and intermolar widths were measured on upper study model with the help of a digital calliper.
The buccal corridor width was least in attractive smile group and maximum in least attractive smile group. The buccal corridor width had a negligible correlation with hard tissues and a mild to moderate inverse correlation with intercanine and intermolar widths within the groups.
As the amount of buccal corridor display was increased, smiling images were scored less attractive by the evaluators. The buccal corridor is not influenced by underlying skeletal hard tissues but have mild to moderate inverse correlation with the intercanine and intermolar width.
本研究旨在评估微笑美学中的颊间隙，并将其与下方的硬组织进行关联。
拍摄了25名年龄在18至25岁之间的男性和25名女性的正面微笑照片、数字化后前位（PA）头影测量片以及研究模型。八名正畸医生、八名整形外科医生、八名美容师和八名外行人对照片的微笑美学进行评估，将其分为三组：最不具吸引力、中等吸引力和最具吸引力的微笑，并测量颊间隙宽度。将数字化PA头影测量片传输到Nemo-tech软件上进行面部正面分析。借助数字卡尺在上颌研究模型上测量尖牙间宽度和磨牙间宽度。
颊间隙宽度在最具吸引力的微笑组中最小，在最不具吸引力的微笑组中最大。颊间隙宽度与硬组织的相关性可忽略不计，而在各组中与尖牙间宽度和磨牙间宽度呈轻度至中度负相关。
随着颊间隙显示量的增加，评估者对微笑图像的吸引力评分降低。颊间隙不受下方骨骼硬组织的影响，但与尖牙间宽度和磨牙间宽度呈轻度至中度负相关。
