摘　　要：目的比较必兰浸润麻醉与利多卡因阻滞麻醉法在下颌第三磨牙阻生齿微创拔牙术中的疗效。方法选择双侧阻生齿拔除患者104名,在同一患者双侧下颌分别行必兰浸润麻醉或2%利多卡因阻滞麻醉,并行高速涡轮机微创拔牙,比较2组的麻醉显效率、麻醉显效时间、术中疼痛程度和术前后收缩压差及无痛持续时间,按配对样本t检验法行统计分析。结果实验组麻醉显效率高于对照组(P=0.024)。实验组软组织麻醉显效时间和牙槽突、牙髓麻醉显效时间分别为(1.04±0.21)、(2.44±2.60)min,较对照组均有降低(P=0.002,P=0.032)。主观疼痛评分优于对照组(P=0.041)。术前后收缩压差明显小于对照组(P=0.018)。实验组无痛持续时间为(103.6±35.5)min,明显高于对照组(P=0.04)。结论必兰浸润麻醉法操作简单,显效时间快且效果可靠,是一种可在下颌第三磨牙阻生齿微创拔牙术中替代2%利多卡因阻滞的改良麻醉方法。Objective To compare the clinical efficacy of the infiltration anesthesia with primacaine and the nerve blocking anesthesia with lidocaine for microport extraction of impacted lower third molar.Methods 104 chosen patients had both sides of impacted lower third molars extracted in this study.Patients were given local anesthesia with either primacaine or lidocaine randomly at each side,and then underwent microport extraction.Clinical factors including effective proportion（EP）,effecting time point（ETP）,visual analogue scale of pain（VASp）,alteration of systolic pressures（ASP） and analgesia duration（AD） were evaluated statistically by means of paired t-test.Results The EP of experimental group was higher than the control group（P=0.024）.The ETP of soft tissue and alveoli-dental pulp was（1.04±0.21）,（2.44±2.60） min in the experimental group,and much earlier than that of the control group（P=0.002, P=0.032）.The VASp and ASP of experimental group were lower than the control group（P=0.041,P=0.018）.AD was（103.6±35.5） min,and higher than the control group（P=0.04）.Conclusion The infiltration anesthesia with primacaine has been proven to be a easier,reliable and quick-acting method.We suggest it an alternative method replacing the 2% lidocaine blocking during microport extraction of impacted lower third molar.
