The purpose of this study was to determine the anesthetic efficacy of inferior alveolar nerve block (IANB) using 4% articaine and 2% lidocaine supplemented with buccal infiltration.
Forty five patients, diagnosed with irreversible pulpitis of a mandibular posterior tooth were included in the study. The first group of 15 patients received 2% lidocaine with 1:200000 epinephrine, the second group 2% lidocaine with 1: 80,000 epinephrine and the third group of 15 subjects received 4% articaine with 1:100000 epinephrine. During the access cavity preparation those patients who complained of pain received an additional buccal infiltration. The percentage of subjects who got profound anesthesia and failure to achieve anesthesia were calculated and tabulated using a visual analog scale.
The results revealed that 87% of subjects who received 4% Articaine with 1:100,000 epinephrine got satisfactory anesthesia with inferior alveolar nerve block alone. Only 2 (13%) subjects received an additional buccal infiltration and none of the patients failed to obtain complete anesthesia with articaine. In comparison only 40% of subjects got complete anesthesia with 2% lidocaine with 1:200000 and 60% with 2% lidocaine with 1:80,000.
It can be concluded that 4% articaine can be used effectively for obtaining profound anesthesia for endodontic procedures in patients with irreversible pulpitis.
本研究旨在确定使用4%阿替卡因和2%利多卡因并辅以颊侧浸润的下牙槽神经阻滞（IANB）的麻醉效果。
本研究纳入了45例被诊断为下颌后牙不可逆性牙髓炎的患者。第一组15例患者接受2%利多卡因加1:200000肾上腺素，第二组15例接受2%利多卡因加1:80000肾上腺素，第三组15例接受4%阿替卡因加1:100000肾上腺素。在开髓预备过程中，主诉疼痛的患者接受额外的颊侧浸润。使用视觉模拟量表计算并列表记录获得深度麻醉和麻醉失败的受试者百分比。
结果显示，接受4%阿替卡因加1:100000肾上腺素的受试者中，87%仅通过下牙槽神经阻滞就获得了满意的麻醉效果。只有2例（13%）受试者接受了额外的颊侧浸润，且使用阿替卡因的患者均未出现麻醉不完全的情况。相比之下，使用2%利多卡因加1:200000的受试者中只有40%获得了完全麻醉，使用2%利多卡因加1:80000的受试者中这一比例为60%。
可以得出结论，4%阿替卡因可有效用于为不可逆性牙髓炎患者的牙髓治疗获得深度麻醉。
