摘要
目的比较下颌高、中位阻生第三磨牙拔除的患者应用无痛口腔局麻仪行牙周膜注射与卡局芯式注射器行下牙槽神经阻滞麻醉注射的麻醉效果。方法随机选择50例行双侧下颌高、中位阻生第三磨牙拔除术的成人患者,同一患者左右侧随机归入试验组和对照组。试验组应用无痛口腔局麻仪行阻生牙牙周膜局部浸润麻醉,对照组应用卡局芯式注射器行下牙槽神经阻滞麻醉,患者本人对两种麻醉方式的注射疼痛程度及效果进行评价。结果两组比较,试验组麻醉注射时疼痛的视觉模拟评分法(visual analogue scale,VAS)值为2.48±0.98,对照组为6.12±0.44,差异有统计学意义(t=3.501,P<0.01)。麻醉效果试验组患者自评为"优"者44例,对照组为35例,两组差异无统计学意义(H=2.833,P=0.812)。结论应用无痛口腔局麻仪行牙周膜局部浸润麻醉更有利于下颌高、中位阻生牙拔除术中的无痛操作。
Objective To compare the effects of two local anesthetic methods （single tooth anesthesia anti conven- tional inferior alveolar nerve block anesthesia） for the extraction of mandibular impaeted third molar （ M3 ）. Methods A total of 50 patients received M3 extraction surgery were randomly divided into two groups. The experimental group （50 cases, same patient, left or right） received single tooth anesthesia （STA）, and the control group （50 cases, same pa- tient, left or right） underwent inferior alveolar nerve block anesthesia. Patients＇ blood pressure and heart rate were meas-ured at various time intervals for the two groups. The value of visual analogue scale （VAS） was recorded and evaluated. Results A higher VAS value and increased blood pressure were observed in the control group, but not in the experimen- tal one. Conclusion Periodontal ligament injection with STA system yielded a significantly low pain score than conven- tional inferior alveolar nerve block anesthesia.
