目的：探讨正畸拔牙与非拔牙病例对牙根吸收的影响。方法：随机选择经过固定正畸治疗，有清晰可辨的矫治前后全口曲面断层片患者108例，其中拔牙54例，非拔牙54例。测量两组治疗前后上、下颌前牙的牙根长度变化。结果：拔牙和非拔牙组正畸治疗前后牙根吸收差异有统计学意义(P＜0.01)。结论：拔牙矫治是正畸治疗中影响牙根吸收的一个重要因素。
目的：探討正畸拔牙與非拔牙病例對牙根吸收的影響。方法：隨機選擇經過固定正畸治療，有清晰可辨的矯治前後全口麯麵斷層片患者108例，其中拔牙54例，非拔牙54例。測量兩組治療前後上、下頜前牙的牙根長度變化。結果：拔牙和非拔牙組正畸治療前後牙根吸收差異有統計學意義(P＜0.01)。結論：拔牙矯治是正畸治療中影響牙根吸收的一箇重要因素。

Objective:To investigate the impact of orthodontic extraction and non extraction cases on root resorption.Method:108 patients with fixed orthodontic treatment and clear panoramic radiographs before and after the treatment were randomly selected. There were 54 cases with extraction,and other 54 cases with non extraction.Then we measured the changes of root length on the mandibular anterior teeth before and after treatment in the two groups.Results:The difference in root resorption before and after orthodontic treatment were statistically significant between the extraction group and non extraction of group(P<0.01).Conclusion:The extraction treatment is one of the important factors affecting root resorption during orthodontic treatment.
