BACKGROUND
The purpose of this study was to analyze the relationship between facial hard and soft tissues in normal Saudi individuals by studying the canonical correlation between specific hard tissue landmarks and their corresponding soft tissue landmarks.
METHODS
A retrospective, cross-sectional study was designed, with a sample size of 60 Saudi adults (30 males and 30 females) who had a class I skeletal and dental relationship and normal occlusion. Lateral cephalometric radiographs of the study sample were investigated using a series of 29 linear and angular measurements of hard and soft tissue features. The measurements were calculated electronically using Dolphin(®) software, and the data were analyzed using canonical correlation.
RESULTS
Eighty-four percent of the variation in the soft tissue was explained by the variation in hard tissue.
CONCLUSION
The position of the upper and lower incisors and inclination of the lower incisors influence upper lip length and lower lip position. The inclination of the upper incisors is associated with lower lip length.
背景
本研究的目的是通过研究特定硬组织标志点与其相应软组织标志点之间的典型相关性，分析沙特正常个体面部硬组织与软组织之间的关系。
方法
设计了一项回顾性横断面研究，样本为60名沙特成年人（30名男性和30名女性），他们具有I类骨骼和牙齿关系且咬合正常。使用一系列29项硬组织和软组织特征的线性和角度测量方法，对研究样本的头颅侧位X线片进行研究。测量值使用Dolphin（®）软件进行电子计算，并使用典型相关性分析数据。
结果
硬组织的变化解释了软组织84%的变化。
结论
上下切牙的位置和下切牙的倾斜度影响上唇长度和下唇位置。上切牙的倾斜度与下唇长度有关。
