The aim of this study was to assess the soft tissue measurements of Iranians with good occlusion and to compare the Iranian norms with other ethnicities.
A total of 25 anthropometric variables were measured by a dentist in 50 Iranian Class I subjects (25 males, 25 females) with good occlusion and well-balanced faces. The differences between the two genders, as well as the differences between Iranian norms and the Holdaway and Burstone analyses, were statistically analyzed using a t-test (α=0.05).
The subjects' mean age was 21.6±4.1 years. There were significant differences between males and females regarding the mentocervical angle, the nasolabial angle, Merrifield's Z-angle, the angle of facial convexity, soft tissue chin thickness, and upper lip thickness (P<0.05). The Holdaway norms can be used for the Iranian population, except for the following measurements which might be significantly different: facial convexity angle, nasolabial angle, interlabial gap, soft tissue facial angle, skeletal profile convexity, H-angle, lower lip to H-line, lower sulcus depth, and soft tissue chin thickness (P<0.05).
There was a considerable sex dimorphism in the Iranian population. The Holdaway norms are not useful for the Iranian population regarding most measurements.
本研究旨在评估咬合良好的伊朗人的软组织测量数据，并将伊朗人的标准与其他种族进行比较。
一名牙医对50名咬合良好且面部比例协调的伊朗I类受试者（25名男性，25名女性）测量了总共25项人体测量变量。使用t检验（α=0.05）对两性之间的差异以及伊朗人的标准与霍尔德韦和伯斯通分析之间的差异进行统计学分析。
受试者的平均年龄为21.6±4.1岁。男性和女性在颏颈角、鼻唇角、梅里菲尔德Z角、面部凸度角、软组织颏厚度和上唇厚度方面存在显著差异（P<0.05）。除以下测量值可能存在显著差异外，霍尔德韦标准可用于伊朗人群：面部凸度角、鼻唇角、唇间隙、软组织面部角、骨骼轮廓凸度、H角、下唇至H线、下沟深度和软组织颏厚度（P<0.05）。
伊朗人群中存在明显的性别二态性。对于大多数测量值而言，霍尔德韦标准对伊朗人群并不适用。
