口唇部活体测量及生长发育研究

报告４３０８例幼儿至青少年期口唇部１１项指标活体测量的均数及性别差异。发现少年以前口部无显著性的性差，唇高等８项指标自１３岁开始，红唇高等３项开始，红唇高等３项指标在１８岁后开始出现明显性差。唇高等６项指标生长发育曲线随年龄增长上升平缓，无生长发育高峰。口裂宽等５项指标的曲线则随年龄增长上升较陡，有明显的发育高峰。

ANTHROPOMETRY AND DEVELOPMENT OF MOUTH, AND LIPS

In this paper the means of 11 items of oral linear measurements taken among 4308 individuals from infant to young periods were reported. The sexual differences were observed. It was seen that the difference was very significant in 8 items including the lip height after 13 years of age, and in 3 items including the vermilion height of the upper and lower lips after 18 years of age, but was not before juvenile period. The devlopment features were observed. It showed that the growth curves rise gradually in 6 items, but in the other items the curves rise obviously showing evident spurts.
