摘要目的比较2%利多卡因与0.5%布比卡因对下颌磨牙不可复性牙髓炎下牙槽阻滞麻醉效果。方法120例患者以随机双盲的方式接受2%利多卡因或0.5%布比卡因下牙槽神经阻滞麻醉。60例接受利多卡因和60例接受布比卡因。牙髓麻醉成功与否是注射之后用牙髓活力电测试仪来评估。测试仪最大读数为80,同时患者无主观感觉,此时定性为麻醉成功。患者在治疗期间对疼痛的主观评价通过视觉模拟评分标尺记录。结果注射后15min之内,120例患者中58例麻醉成功,利多卡因注射后麻醉成功32例,布比卡因注射后麻醉成功26例(P=0.273);89例接受了无痛治疗,利多卡因注射后无痛治疗40例,布比卡因注射后无痛治疗49例(P=0.061)。结论在下颌磨牙不可复性牙髓炎治疗中,利多卡因和布比卡因的下牙槽神经阻滞麻醉效果无明显性差异。 Objective The purpose of this study is to compare the anesthetic effects of 2% Lidocaine and 0.5% Bupivacaine for inferior alveolar nerve block anesthesia for the treatment of irreversible pulpitis at the mandibular molar. Methods A total of 120 patients were randomly grouped to be given 2% Lidocaine or 0.5% Bupivacaine respectively in a double blinded manner for inferior alveolar nerve block anesthesia. The success of dental pulp anesthesia was assessed by an electric dental pulp activity tester. The anesthesia is considered as successful if there is no reaction from the patient when the tester is used to stimulate the teeth of the patient to the maximum value of 80 after the anesthesia. Painless treatment is based on the fact that the treatment can be completed while there is no feeling of pain or only a slight feeling of pain from the patient. Once the patient experiences any feeling of medium or high level of pain during the operation, the painless treatment is considered to be failed. The subjective assessment of the pain from a patient during the treatment was recorded following the Visual Analogue Scale （VAS）. Results Successful anesthesia was achieved in 58 out of the 120 cases 15 minutes after injecting the anesthetic agent. There were 32 successful anesthesia cases after injecting Lidocaine and 26 successful anesthesia cases after injecting Bupivacaine （P=0.273）. And 89 out of the 120 cases received successful painless treatment, 40 cases after injecting Lidocaine and 49 cases after injecting Bupivacaine （P= 0.061 ）. Conclusion There are no significant differences between the anesthetic effects of Lidocaine and Bupivacaine inferior alveolar nerve block anesthesia for the treatment of irreversible pulpitis at the mandibular molar.
