目的：通过随机对照试验，比较改良下牙槽神经阻滞麻醉与传统方法的教学疗效。方法40名参与者分组采用两种下牙槽神经阻滞麻醉方法，对比麻醉起效时间、麻醉成功率、麻醉回抽出血率。结果改良注射法麻醉起效时间为（2.5±1.2）min，传统注射方法为（4.4±3.2）min。前者麻醉成功率98.75%，后者成功率90%，差异有统计学意义（P＜0.05）。两种方法的麻醉回抽出血率差异无统计学意义（P＞0.05）。结论改良下牙槽神经阻滞麻醉教学疗效明显优于传统方法，两种方法都可应用于教学及临床，但改良下牙槽神经阻滞麻醉效果更佳，起效时间更短，更利于初学者掌握，能够显著提升初学者的麻醉成功率。

Objective Through randomized controlled trials, we evaluated the clinical effects and teaching effects of two different methods of block anesthesia of inferior alveolar nerve. Methods In order to study the anesthesia effect, successful rate and hemorrhage rate, 40 participants randomly divided into two groups. Two different kinds of block anesthesia of inferioralveolar nerve were caried out. Results Improved injection onset time of anesthesia for (2.5±1.2) min, the traditional injection method for (4.4±3.2)min. The former anesthesia success rate was 98.75%, the latter 90% success rate, success rate was statistically significant (P<0.05). Two methods of anesthesia to bleed rate had no significant difference (P>0.05). Comclusion Analyzed and compared these two methods, they both can used in teaching and clinical operation. The modiifed method was signiifcant super to the traditional method. The modiifed method could signiifcantly increase the successful rate of beginners.
