摘要
目的 :探讨性别因素在正畸治疗中对牙根吸收的影响作用。方法 :配对测量正畸治疗前后牙根长度及牙根等级 ,分析牙根吸收及其分布的情况。结果 :男性组和女性组正畸治疗前后牙根长度改变有统计学意义 (P <0 0 1)。正畸治疗前后牙根等级分布改变有统计学意义 (P <0 0 1)。但两组之间的组间差异没有统计学意义 (P >0 0 5 )。结论
Objective:To deterrmine the relation between root resorption and root resorption distribution to sex factors Methods:Paired pretreatment and posttreatment measurements were taken of the root length of four roots in the three selected teeth on cephalograms and root degrees of all visual root shape on panoral radiographs Then analyze root resorption and its distribution Results:Root resorption occurred during orthodontic treatment in each group However there seemed no statistically significant between groups no matter root length or root degrees Conclusion:The factor of sex was not the major factor which could influence root resorption during orthodontic treatment
