目的建立本地区正常青少年X线头影测量值标准。方法选择120例常州籍汉族正常青少年拍摄头颅定位侧位X线片,用Steiner及Tweed分析方法做角度测量及线距测量。男、女青少年间进行比较,观察不同性别正常值间的差异;分别和长春、西安男、女青少年进行比较,观察不同地区同一性别青少年正常值间的差异。对所有测量结果进行统计分析。结果建立了常州地区汉族正常青少年硬组织的X线头影测量正常值标准,并比较性别差异及地区差异。结论同一地区不同性别正常青少年Steiner及Tweed分析法测量值间差异无统计学意义;不同地区正常青少年X头影测量值间有一定的差异。
Objective To establish the standard of X-cephalometry for normal young adults in this area. Methods One hundred and twenty cases of normal Han children from Changzhou were enrolled in this study. X-ray films of craniofacial location were taken. Angle measurement and line distance measurement were performed by Steiner and Tweed analysis. Male and female adolescents were compared to observe the gender differences between the normal; respectively, and Changchun, Xi’an male and female adolescents were compared to observe the difference between the normal gender adolescents in different regions. Statistical analysis of all measurements. Results The normal standard of X-cephalometry of normal hard-haired adolescents in Changzhou was established, and the gender differences and regional differences were compared. Conclusion There was no significant difference between the Steiner and Tweed values of the adolescents with different genders in the same area. There was a certain difference between the X cephalometric values of the adolescents in different areas.
