必兰局部浸润麻醉与利多卡因下牙槽神经阻滞麻醉治疗下颌磨牙急性牙髓炎镇痛效果的比较

目的：探讨必兰局部浸润麻醉与利多卡因下牙槽神经阻滞麻醉治疗下颌磨牙急性牙髓炎的镇痛效果。方法将94例下颌磨牙急性牙髓炎患者随机分为两组，实验组采用必兰局部浸润麻醉，对照组采用利多卡因下牙槽神经阻滞麻醉。麻醉5-10min后，施行开髓及牙髓摘除术，记录并统计医生和患者综合评价麻醉效果。结果两组开髓和拔髓的麻醉效果均无统计学差异(P>0.05)。结论必兰局部浸润麻醉在下颌磨牙急性牙髓炎的治疗过程中，可以取得与利多卡因下牙槽神经阻滞麻醉相近的麻醉成功率；考虑到患者感受和麻醉并发症，可首选必兰局部浸润麻醉。

Anesthetic efficacy of local infiltration anesthesia with Primacaine Adrenaline and inferior alveolar nerve block anesthesia with Lidocaine Hydrochloride in patients with acute pulpitis in mandibularmolar

Objective To demonstrate the anesthetic efficacy of local Infiltration anesthesia with Primacaine Adrenaline and conduction anesthesia of inferior alveolar nerve with Lidocaine Hydrochloride in Patients with Acute Pulpitis in Mandibular Molar. Methods Ninety four patients with acute pulpitis were randomly divided into two groups, Group A： local infiltration anesthesia with Primacaine Adrenaline, Group B： conduction anesthesia of inferior alveolar nerve with Lidocaine Hydrochloride. Five to ten minutes after anesthesia, endodontic access and pulpectomy were performed and the effects of anesthesia were assessed. Results There are no significant difference between two groups statistically（P〉0.05）. Conclusion During the therapy of acute pulpitis in mandibular molar the anesthetic effect of local infiltration anesthesia with Primacaine Adrenaline has the similar effect with inferior alveolar nerve block anesthesia with Lidocaine Hydrochloride. Considering the feelings of patients and anesthetic syndrome, the pulpectomy of the acute pulpitis in mandibular molar.
