摘要
目的:建立西安地区陕西籍正常牙合成人软组织X线头影测量正常值标准,并与西安地区正常牙合青少年软组织X线头影测量值进行比较。方法:选取西安市18～22岁的在校学生正常牙合120名(男、女各半)。所有研究对象均在头颅定位仪的严格定位下,摄取其正中咬合位时的X线头颅侧面定位片;用绘图铅笔在透明硫酸纸上定点、描图,然后经由图形数值化仪输入计算机内进行测量并进行统计处理。结果:获得3种头影测量软组织分析法的正常值;其中有一些角度及线距测量结果与西安地区正常牙合青少年相比有显著性差异。结论:通过上述方法获得3种头影测量软组织分析法的正常值,可以用于指导临床。
Objective:To establish the cephalometric norms of soft tissue of adults in Xi'an area with normal occlusion.Methods:120 college students with normal occlusion(60 male and 60 female), aged from 18-22 years old in Xi'an city were selected.Lateral cephalometric film was taken by cephalometer for all the subjects at intercuspal occlusion.Then the films were traced on vitriolic paper, and the points were put into computer through digitizier. Statistic analysis were made and the data were compared with norms of adolescents already obtained.Results:Studied by Holdaway analysis,in the males FH-PgG' and Li-Pg' Ls of adults were bigger than those of adolescents, while Ss-Ls,Sn-H,Ls-Si and H-N'pg' were smaller(P<0.05 or P<0.01). In the females A-Sn,Ls-Si and Li-pg' Ls of adults were bigger than those of adolesents, while Ss-L was smaller(P<0.01). The other measurments of the adults were not significantly different from those of adolescents(P>0.05).Conclusion:The 3 sets of norms of soft tissue analysis obtained through this study may be applied as the norms of adults with normal occlusion.
