OBJECTIVE
To determine soft tissue cephalometric norms of a sample of Jordanian adolescents and to compare them with those of North Americans.
MATERIALS AND METHODS
Forty-one subjects aged 14 to 17 years were selected from a larger random and representative sample of 320 adolescents attending 12 schools in the capital of Jordan, Amman. Seven reference lines were identified and traced according to definitions by Holdaway and Ricketts, and 2 angular and 12 linear measurements were analyzed.
RESULTS
Significant differences were found between males and females in measurements of soft tissue facial angle, H angle, subnasale to H line, basic upper lip thickness, upper lip thickness and labrale inferius and superius to E line (P < .05). Males had a more prominent upper lip in relation to the overall soft tissue profile, while the lips of females were considerably more retrusive in relation to the nose and chin. Jordanian norms were similar to those of North Americans, with only two exceptions: the H angle and skeletal convexity which were 5.4 degrees and 3.2 mm greater in Jordanians, respectively.
CONCLUSIONS
Jordanian soft tissue norms were similar to American norms with the exception of the former having a more prominent upper lip position in relation to the overall soft tissue profile.
目的
确定约旦青少年软组织头影测量的正常值，并与北美人的正常值进行比较。
材料和方法
从 320 名在约旦首都安曼的 12 所学校就读的青少年中随机抽取的更大样本中选择了 41 名年龄在 14 至 17 岁的受试者。根据 Holdaway 和 Ricketts 的定义确定并追踪了 7 条参考线，并分析了 2 个角度和 12 个线性测量值。
结果
男性和女性在软组织面角、H 角、下鼻底至 H 线、基础上唇厚度、上唇厚度和下唇下边缘和上边缘至 E 线的测量值上存在显著差异（P <.05）。男性的上唇相对于整个软组织轮廓更为突出，而女性的嘴唇相对于鼻子和下巴明显更为退缩。约旦的正常值与北美的正常值相似，只有两个例外：H 角和骨骼凸度，约旦人分别大 5.4 度和 3.2 毫米。
结论
除了约旦人的上唇位置相对于整个软组织轮廓更为突出外，约旦的软组织正常值与美国的正常值相似。
