摘　　要：目的:比较电动式微动力系统和气动式手机在下颌阻生第三磨牙拔除术中的临床效果。方法:对106例患者的212颗下颌双侧第三磨牙分2次拔除,采用随机、交叉、自身对照方法,分别采用电动式微动力系统和气动式手机进行阻生牙拔除术。记录并比较患者手术时间及术中、术后并发症发生情况。采用SPSS 21.0软件包对数据进行统计学分析。结果:电动式微动力组手术时间较短,术后第1天肿胀、疼痛程度均轻于气动式手机组(P<0.05)。结论:电动式微动力系统拔除下颌阻生第三磨牙优于气动式手机,值得临床应用。PURPOSE:To investigate the value of electro-microdynamic system compared with impact air handpiece during impacted mandibular third molar removal.METDODS:The 212 mandibular bilateral third molars of 106 patients were extracted in 2 times through a randomized,split-mouth clinical trial.Electro-microdynamic system and impact air handpiece were used respectively.The extraction time,intraoperative and postoperative complications of two groups of patients were recorded and compared statistically with SPSS 21.0 software package.RESULTS:The extraction time,swelling and postoperative pain on the 1 st day were significantly lower in patients with electro-microdynamic system than in patients with impact air handpiece(P<0.05).CONCLUSIONS:Using electro-microdynamic system can reduce postoperative pain and swelling,which is worthy of clinical application.
