摘　　要：目的:建立山东省正常少年儿童各骨龄分期内多项头影测量项目的正常值范围及标准差,研究其牙颌颅面生长发育规律,比较各骨龄分期间及性别间的差异。方法:选择172名山东籍汉族正常少年儿童,拍摄X线头颅定位侧位片,通过WinCeph7.0软件进行图像处理,对样本进行骨龄分期及定点测量,采用SPSS 18.0软件包对数据进行统计学处理。结果:男性面型轮廓整体较女性大;下颌平面随生长发育发生逆时针旋转,男性较女性为甚;男性上前牙较女性唇倾,下前牙较女性直立,突度均随着生长发育逐渐减小;男性下唇较女性厚。结论:建立山东省正常少年儿童各骨龄分期内多项头影测量项目的正常值范围及标准差,并得出山东省正常少年儿童生长发育过程中性别间及各骨龄组间的差异。PURPOSE： To establish the normal values of cephalometric items for children with normal occlusion in Shandong province, and study the growth tendency of them and analyze the characteristics in different skeletal stages and sexes. METHODS： Lateral cephalograph was taken in 172 children of Hart nationality with normal occlusion in Shandong province. The pictures were processed by WinCeph7.0, and statistical analysis was carried out using SPSS18.0 software Package. The results between sexes and 4 skeletal stages were compared. RESULTS-＇ Facial contour in males were larger than in females. With growth of children, counter-clockwise rotation happened in mandibular plane, and males rotated more than females. Maxillary anterior tooth tilted more forword in males than in females, while mandibular anterior tooth positioned more upright in males than in females, and the protrution of maxillary and mandibular anterior tooth in males decreased along with growth. The lower lip in males was thicker than in females. CONCLUSIONS： The normal values and standard deviations of measuring items in different gender and bone-age group were established.
