With the shift in focus from the hard to soft tissue in orthodontic diagnosis and treatment planning, the scope of orthodontic treatment has grown beyond achieving an ideal occlusion, also to achieve ideal aesthetic facial proportions. Since time immemorial, the various horizontal and vertical proportions of an ideal face is considered to follow the golden/divine ratio.
The aim of this study is to assess the vertical and horizontal proportions of the face and their relation of phi in males and females of Dakshina Kannada population.
The study was carried out on 100 subjects, which included 50 males and 50 females, aged between 18 and 30 years. Photographs were taken under standardized condition and adjusted to a standardized image size (5″ × 4″). Adobe Photoshop CS5.1 software was used for making all the measurements. A total of 11 vertical and horizontal ratios were independently measured for males and females, and their relation to phi was assessed. The data were subjected to Shapiro-Wilk test for testing the normality. Homogeneity of variance assumption was tested by using Levene statistic homogeneity of variance. One sample t test was used for the comparison between phi and mean vertical and horizontal ratios in males and females.
In males and females of the Dakshina Kannada, a statistically significant correlation was seen between all the horizontal and vertical facial proportions and phi (p < 0.05). Between male and female groups, a significant difference was noted in the intertemporal/intercanthal ratio, interalae/nose width and Intereye-soft menton/ala-soft menton (p < 0.05).
Golden proportion can be used as a guideline in orthodontic treatment planning. However, it should not be the decisive factor in determining the facial attractiveness.
随着正畸诊断和治疗计划从关注硬组织向软组织的转变，正畸治疗的范围已从实现理想的咬合扩大到实现理想的面部美学比例。自古以来，理想面部的各种水平和垂直比例被认为遵循黄金/神圣比例。
本研究的目的是评估南卡纳塔克邦人群中男性和女性面部的垂直和水平比例及其与黄金分割比的关系。
该研究对100名受试者进行，其中包括50名男性和50名女性，年龄在18至30岁之间。在标准化条件下拍摄照片，并调整为标准化图像尺寸（5英寸×4英寸）。使用Adobe Photoshop CS5.1软件进行所有测量。分别对男性和女性独立测量了总共11个垂直和水平比例，并评估了它们与黄金分割比的关系。对数据进行Shapiro-Wilk检验以检验正态性。使用Levene统计方差齐性检验方差齐性假设。使用单样本t检验比较男性和女性的黄金分割比与平均垂直和水平比例。
在南卡纳塔克邦的男性和女性中，所有面部水平和垂直比例与黄金分割比之间均存在统计学上的显著相关性（p < 0.05）。在男性和女性组之间，颞间/内眦间比例、鼻翼间/鼻宽以及眼间-软颏点/鼻翼-软颏点之间存在显著差异（p < 0.05）。
黄金比例可作为正畸治疗计划的指导原则。然而，它不应是决定面部吸引力的决定性因素。
