This study aimed to identify and establish the facial and smile proportions in young adults and to compare the results with ideal or divine proportions, compare the proportions of males and females included in our study population and compare them with those established for Caucasian and Japanese populations.
Two hundred participants (164 females, 36 males) with Angle's class I malocclusion (M.O). and well-balanced faces were selected and photographed in the frontal repose position. Analysis was done in Adobe Photoshop software. Statistical analysis was done using the Statistical Package for the Social Sciences version 17.0. (IBM Corporation Armonk, New York, United States).
Results suggested that females are more near to ideal ratios and males are more deviated from the ideal ratios. The proportions of males and females were not considerably different from each other. In Indian population, upper 3 facial height (TR-LC) was increased and mid-face height (LC-LN) was decreased; in lower 3 of the face, LN-CH was slightly increased in comparison to CH-ME. In facial widths, outer canthal width (LC-LC) was greater in the Indian population and mouth width (CH-CH) was normal. When compared with Indian population, Japanese participants had wider noses, outer canthal distance, and bitemporal width.
It was concluded that significant difference was found between the proportions of the Indian population and ideal ratio. When Indian population was compared with Japanese and Caucasian populations, some parameters of facial proportions showed significant difference, which leads to the need for establishing standardized norms for various facial proportions in Indian population.
本研究旨在确定并建立年轻成年人的面部及微笑比例，将结果与理想或神圣比例进行比较，比较本研究人群中男性和女性的比例，并将其与为白种人和日本人群建立的比例进行比较。
选取200名安氏I类错（牙合）（M.O.）且面部比例协调的参与者（164名女性，36名男性），在正面静息位进行拍照。在Adobe Photoshop软件中进行分析。使用社会科学统计软件包第17.0版（美国纽约州阿蒙克市IBM公司）进行统计分析。
结果表明，女性更接近理想比例，男性则更偏离理想比例。男性和女性的比例彼此之间没有显著差异。在印度人群中，面部上三分之一高度（TR-LC）增加，面中高度（LC-LN）降低；在面部下三分之一，与CH-ME相比，LN-CH略有增加。在面部宽度方面，印度人群的外眦宽度（LC-LC）更大，口宽（CH-CH）正常。与印度人群相比，日本参与者的鼻子更宽、外眦距离和双颞宽度更大。
得出的结论是，印度人群的比例与理想比例之间存在显著差异。当将印度人群与日本和白种人群进行比较时，面部比例的一些参数显示出显著差异，这导致需要为印度人群建立各种面部比例的标准化规范。
