摘要
目的探讨环境和遗传因素在混合牙列期对软组织面平面的影响,为确立牙齿的正确矫治计划提供理论依据。方法测量6~12岁183对双生子女童的头颅侧位片,利用双生子法得出生长发育过程中环境和遗传因素对颅面软组织侧貌产生的影响。结果F3鼻下点、F4上唇凹点、F5上唇突点、F6上口点、F7下口点、F8下唇突点、F9下唇凹点、F10软组织颏下点均受到环境因素的影响(P<0.05)。其中,F7下口点、F8下唇突点受环境影响的作用比较大,F3鼻下点、F4上唇凹点、F9下唇凹点同时受到环境和遗传因素的影响。结论下唇部受环境因素的影响较大,而鼻下点、上唇凹点和下唇凹点受到环境和遗传因素的共同影响。
Objective To study the relative effects of environment and genes on the soft tissue surface plane during the mixed dentitions,and to provide theoretical evidence to establish the correct teeth treatment plan.Methods The lateral cephalograms of one hundred and eighty-three female twins from six to twelve years old were studied.The environmental and genetic effects were analyzed on soft tissue profile by twin method.Results The influence of environmental factors was detected by measurement items of subnasale(F3),upper lip concave point(F4),upper lip sudden point(F5),upper stomion(F6),lower stomion(F7),lower lip sudden point(F8),lower lip concave point(F9),menton of soft tissue(F10)(P<0.05).Among them,lower stomion(F7)and lower lip sudden point(F8)were more affected by environmental impact,the influence of environmental and genetic factors was detected by measurement items of subnasale(F3),upper lip concave point(F4),and lower lip concave point(F9).Conclusion The lower lip is more be influenced by environmental factors,whereas the subnasale,upper lip concave point,and lower lip concave point are mainly by both the environmental and genetic factors.
