重庆地区正常人头影测量Coben及Wits分析与颅面结构特征的研究

Cephalometric norms of Coben and Wits analysis of adults and adolescents with normal occlusion in Chongqing and the study of the characterastics of craniofacial structure

目的 :建立重庆地区正常人群Coben、Wits分析法的正常值 ,探讨颅颌面结构的地区、性别特征。方法 :选择 182例重庆籍正常样本 ,成人 42例 (男 19例 ,女 2 3例 ) ,年龄 18-2 1岁 ;儿童 14 0例 (男 62例 ,女 78例 ) ,年龄 12— 16岁。所有样本拍摄X线头颅定位侧位片 ,进行头影测量及男女间、儿童与成人间的比较。并与上海地区成人Coben分析法的正常值作比较。结果 :得到重庆地区正常人群Coben、Wits分析法的正常值。儿童与成人间差别体现在线距方面。男女间在线距、比例指数上均存在差别 ,经成组t检验 ,多变量方差分析有统计学意义。线距项目正常值重庆地区与上海地区调查结果存在差别 ,比例指数项目基本无差别。结论 :Coben分析法正常值男女间颅面部大小、比例关系上存在差别 ,不同地区人群头影测量值存在差别。

Objective:To obtain cephalometric norms of Coben and Wits analysis with normal occlusion in Chongqing.To analyze the different feature of cranio-maxilla-facial structures between male and female, between different area. Method: Lateral cephalogram of adolescents (male 62, female 78) and adults(male 19, female 23) with normal occlusion in Chongqing were taken. Coben and Wits analysis were conducted. Data were compared with those obtained in adult in Shanghai ,and value of male and female were compared by one sample t-Test and MANOVA (multivariate analysis of variance). Result: There were significant difference in normal value between male and female, between different area.Conclusion: There were different feature of cranio-maxilla-facial structures between male and female. Cephalometric norms were different between Chongqing and Shanghai .
