Abstract:
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.
