The purpose of this study was to determine the pain associated with needle insertion (with or without topical anesthetic) and solution deposition for the long buccal nerve block injection in patients with irreversible pulpitis. Initial pain and any differences by age and gender were also studied.
One hundred twelve emergency patients with irreversible pulpitis received long buccal nerve block injections using 2% lidocaine with 1:100,000 epinephrine. The patients recorded pain of needle insertion and solution deposition on a Heft-Parker visual analog scale (VAS).
Moderate-to-severe pain occurred from 41% to 46% of the time with the long buccal nerve block. The use of topical anesthetic did not statistically decrease the pain of needle insertion.
In conclusion, 41% to 46% of patients presenting with irreversible pulpitis have the potential for moderate-to-severe pain with the long buccal nerve block.
本研究旨在确定不可逆性牙髓炎患者行长颊神经阻滞注射时，进针（使用或不使用局部麻醉剂）及注射溶液时的疼痛情况。同时研究初始疼痛以及年龄和性别造成的任何差异。
112例不可逆性牙髓炎急诊患者接受了使用含1:100,000肾上腺素的2%利多卡因进行的长颊神经阻滞注射。患者使用赫夫特-帕克视觉模拟量表（VAS）记录进针和注射溶液时的疼痛情况。
长颊神经阻滞时，41%至46%的时间会出现中度至重度疼痛。使用局部麻醉剂在统计学上并未减轻进针时的疼痛。
总之，41%至46%的不可逆性牙髓炎患者在接受长颊神经阻滞时有可能出现中度至重度疼痛。
