To analyze the characteristics soft tissue profile in Hunan Han adults with normal occlusion and to explore the differences of the soft tissue profile in gender, region and race.
Lateral cephalometric radiographs were performed for 323 volunteers (164 females and 159 males) from Hunan Province. The digital cephalometric radiographs were imported into the WinCeph8.0 measurement and analysis system in a same computer. According to the Holdaway analysis method, the mean and standard deviation were calculated. Then the results were compared to the data from Liaoning, Nepalese, Japanese, North American Caucasians.
The normal value of cephalometric facial soft tissue profile in Han population adults with normal occlusion in Hunan Province were obtained. There were significant differences in subnasale to H line (Sn-H), upper lip tension, lower lip sulcus depth (Si-PgsLs), and soft tissue chin thickness (Pg-Pgs) between males and females (all P<0.05). Compared with Liaoning Province, significant regional differences in soft tissue facial angle (FH-NsPgs), upper lip sulcus depth (Ss-Ls), Sn-H, lower lip thickness, upper lip thickness, H angle, lower lip to H line (Li-PgsLs), Si-PgsLs, and Pg-Pgs were found in Hunan Province (all P<0.05). Compared with the Japan, significant regional differences in FH-NsPgs, nose prominence (Sn-Pn), lower lip thickness, upper lip tensity, H angle, Li-PgsLs, Si-PgsLs, and Pg-Pgs were found in Hunan Province (all P<0.05). Compared with the Nepalese, significant regional differences in Sn-Pn, Ss-Ls, Sn-H, skeletal profile convexity (A-NPs), basic upper lip thickness, upper lip tensity, H angle, Li-PgsLs and Pg-Pgs were found in Hunan Province (all P<0.05). Compared with the North America, significant regional differences in Sn-Pn, Ss-Ls, Sn-H, A-NPs, basic upper lip thickness, upper lip tensity, H angle, Li-PgsLs, Si-PgsLs and Pg-Pgs were found in Hunan Province (all P<0.05).
There are both similarities and differences in facial soft tissue profile between males and females with normal occlusion in Hunan Province. The characteristics of facial soft tissue profile in Hunan Province are different from that in Liaoning area, Nepal, Japan and North America.
分析湖南汉族正常牙合成年人的软组织侧貌特征，探讨性别、地区及种族间软组织侧貌的差异。
对323名来自湖南省的志愿者（164名女性和159名男性）拍摄头颅侧位片。将数字化头颅侧位片导入同一台计算机中的WinCeph8.0测量分析系统。按照Holdaway分析法计算均值和标准差。然后将结果与来自辽宁、尼泊尔、日本、北美白种人的数据进行比较。
得出湖南省汉族正常牙合成年人头颅测量面部软组织侧貌的正常值。男女之间在鼻下点至H线（Sn-H）、上唇紧张度、下唇沟深度（Si-PgsLs）和软组织颏厚度（Pg-Pgs）方面存在显著差异（均P<0.05）。与辽宁省相比，湖南省在软组织面角（FH-NsPgs）、上唇沟深度（Ss-Ls）、Sn-H、下唇厚度、上唇厚度、H角、下唇至H线（Li-PgsLs）、Si-PgsLs和Pg-Pgs方面存在显著的地区差异（均P<0.05）。与日本相比，湖南省在FH-NsPgs、鼻突度（Sn-Pn）、下唇厚度、上唇紧张度、H角、Li-PgsLs、Si-PgsLs和Pg-Pgs方面存在显著的地区差异（均P<0.05）。与尼泊尔人相比，湖南省在Sn-Pn、Ss-Ls、Sn-H、骨骼侧貌凸度（A-NPs）基本的上唇厚度、上唇紧张度、H角、Li-PgsLs和Pg-Pgs方面存在显著的地区差异（均P<0.05）。与北美相比，湖南省在Sn-Pn、Ss-Ls、Sn-H、A-NPs、基本的上唇厚度、上唇紧张度、H角、Li-PgsLs、Si-PgsLs和Pg-Pgs方面存在显著的地区差异（均P<0.05）。
湖南省正常牙合男女的面部软组织侧貌既有相似之处，也有差异。湖南省面部软组织侧貌特征与辽宁地区、尼泊尔、日本和北美不同。
