目的：???比较牙挺冲击法和撬拔法在牙周间隙减小的牙根拔除术中的临床效果。方法??收集多个牙位的单根牙牙根140个，随机分成2组，牙挺冲击法组72个，牙挺撬拔法组68个。分别记录手术时间，比较手术时间和手术并发症的情况。结果???牙挺冲击法和撬拔法拔除牙根的手术时间分别为（2.15±0.55）min及（4.03±0.88）min （P<0.01）。术中牙龈撕裂和牙槽突骨折的发生率2组差异有统计学意义（P<0.05），术中断根的发生率2种手术方法差异无统计学意义（P>0.05）。应用牙挺冲击法术后疼痛的发生率低于牙挺撬拔法（P<0.05）且上皮覆盖拔牙创的时间较应用牙挺撬拔法短（P<0.01）。2种手术方法术后均未见出血病例，应用牙挺撬拔法发生干槽症的患者有1例。结论???采用牙挺冲击法拔除牙根的手术时间短、并发症少，有利于拔牙创的愈合。
