阿替卡因两种麻醉方式在下颌后牙拔除术中麻醉效果的对比

Comparation of Anesthetic Effect of Articaine in the Extraction of Mandibular Posterior Teeth under Local Anesthesia and Periodontal Membrane Anesthesia

目的比较复方阿替卡因局部浸润麻醉与牙周膜腔麻醉2种方式在下颌后牙拔除术中的麻醉效果。方法随机选择204名患者,分为局部浸润麻醉组及牙周膜腔麻醉组,采用标尺法由患者对疼痛程度进行打分;口腔医生评价麻醉效果,统计麻醉完全、良好、有效和失败的比例。结果达到麻醉完全效果的牙周膜腔麻醉与局部浸润麻醉组有显著性差异(P<0.05),两种麻醉方式成功率无显著性差异(P>0.05)。结论用牙周膜腔麻醉效果优于局部浸润麻醉方式。

Objective To compare the anesthetic effect of articaine under local anesthesia and periodontal membrane anesthesia on the extraction of mandibular posterior teeth. Methods 204 patients were randomly divided into two groups：local anesthetic group and periodontal membrane anesthetic group. Patients in each group were an- esthetized by local anesthesia or periodontal membrane anesthesia, The anesthetic effect was analyzed. Results The excellence rate of periodontal membrane anesthetic group was 84.3 %. Conclusion Periodontal membrane anesthesia for the extraction of mandibular posterior teeth using articaine is more effective than local anesthesia.
