摘要: 目的 获得畲族青少年正常Downs头影测量结果,比较其与汉族青少年正常头影测量结果的差异。方法 选择浙江丽水地区正常畲族青少年男女共200名,汉族青少年男女共200名,拍摄X线头影侧位定位片,应用Downs分析法进行测量分析,采用SPSS 12.0软件包对各组间数据进行配对t检验。结果 通过畲族青少年正常Downs头影测量分析,获得了畲族青少年正常头影测量的正常值,对各性别及种族测量结果进行比较,发现畲族青少年、汉族青少年男性与女性间各项指标均无显著差异;与汉族青少年相比,畲族青少年男性及女性下颌平面角,上、下中切牙角均显著增加(P<0.05),颌凸角显著减小(P<0.05)。此外,畲族青少年女性下切牙唇倾度较汉族青少年女性显著减小(P<0.05),而两族其他指标均无显著差异。结论 畲族青少年较汉族青少年面型更偏直面型,呈现出垂直生长趋势,而畲族与汉族青少年面型均无显著性别差异。

Abstract: PURPOSE: To investigate the clinical normal values of juveniles with normal occlusions of She and Han nationality in Lishui area of Zhejiang province, and compare the craniofacial characteristics between She and Han nationality. METHODS: Two hundred juveniles of She nationality and 200 juveniles of Han nationality with normal occlusion were recruited. Lateral cephalometric radiographs were taken, and Downs cephalometric analysis was performed. The data were compared using paired samples t test with SPSS 12.0 software package. RESULTS: There was no significant difference between males and females in the values of juveniles of both She and Han nationality. Compared to the male and female juveniles of Han nationality, MP-FH and U1-L1 of the She juveniles increased (P<0.05), while convexity decreased significantly (P<0.05). In addition, L1-MP of She female juveniles decreased significantly in comparison to that of Han female juveniles (P<0.05). There was no significant difference in other values between She and Han nationality. CONCLUSIONS: Compared to Han juveniles, She juveniles present an orthognathous and long face with vertical growth pattern. Sex differences are not apparent in juveniles of both She and Han nationality.
