目的 观察碧兰麻在牙髓治疗中的局部麻醉效果。方法 将碧兰麻 (含 4%阿替卡因加 1/10 0 ,0 0 0肾上腺素 )用于牙髓治疗麻醉共 2 2 9例 ,均局部粘膜下浸润注射 ,采用VAS(VisualAnalogueScale)标尺法评价麻醉效果 ;将患牙分为上前牙组、上后牙组、下前牙组和下后牙组 ,并对各组麻醉效果进行评价分析。结果 2 2 9例患牙麻醉总有效率 10 0 % ,总优良率76 86% ,上前牙组、上后牙组、下前牙组、下后牙组麻醉优良率分别为 93 18%、92 3 1%、94 74%、5 1 14 %。经统计学处理 ,前三组无显著性差异 (P >0 0 5 ) ,均与下后牙组有显著性差异 (P <0 0 1)。结论 碧兰麻是安全有效的局部麻醉药物 ,且对上前牙组、上后牙组、下前牙组牙髓麻醉优良率高于下后牙组。
Objective To observe the effect of local anesthesia in the treatment of pulsating pulp. Methods A total of 2 229 patients were treated with penicillamine (containing 4% articaine plus 1/10 0, 0 0 0 epinephrine) for endodontic anesthesia. All patients were infiltrated with submucosal infiltration. VAS (Visual Analog Scale) Method to evaluate the effect of anesthesia; the teeth were divided into upper anterior teeth group, upper teeth group, lower anterior teeth group and lower posterior teeth group, and evaluated the anesthetic effect of each group. Results The total effective rate was 102%. The total excellent rate was 76.86%. The excellent and good rates of anesthesia in upper anterior teeth group, upper posterior teeth group, lower anterior teeth group and lower posterior teeth group were 93.18% 92 3 1%, 94 74%, 5 1 14%. There was no significant difference between the first three groups (P> 0.05) and the lower posterior teeth group (P <0.01) after statistical analysis. Conclusion Botanine is a safe and effective local anesthetic, and the superior rate of dental pulp anesthesia to upper anterior teeth group, upper posterior teeth group and lower anterior teeth group is higher than lower posterior teeth group.
