We compared the anesthetic efficacy of inferior alveolar nerve blocks (IANBs) with that of buccal infiltrations (BIs) in mandibular first molars. Using a crossover design, all subjects received a standard IANB or a BI of 1.7 mL of 4% articaine with 1:100,000 adrenaline (Septanest; Septodont, Saint-Maru-des-Fosses, France) on two appointments separated by at least 1 week. Pulpal anesthesia was determined by using an electric pulp tester. Electric pulp testing was repeated at 5, 8, 11, 15, 20, 25, and 30 minutes after the injections. Anesthesia was considered successful if the subject did not respond to the maximum output of the pulp tester at two or more consecutive time points. Fifty-four percent of the BI and 43% of the IANB were successful; the difference was not significant (p = 0.34). The onset of pulpal anesthesia was significantly faster with BI (p = 0.03). In conclusion, BI with 4% articaine for mandibular first molars can be a useful alternative for clinicians because compared with IANB it has a faster onset and a similar success rate.
我们比较了下牙槽神经阻滞（IANB）与颊侧浸润（BI）在下颌第一磨牙的麻醉效果。采用交叉设计，所有受试者在至少间隔1周的两次就诊时分别接受一次标准IANB或一次1.7 mL含1:100,000肾上腺素的4%阿替卡因颊侧浸润（Septanest；Septodont公司，法国圣马尔叙德福斯）。使用牙髓电活力测试仪确定牙髓麻醉情况。在注射后5、8、11、15、20、25和30分钟重复进行牙髓电活力测试。如果受试者在两个或更多连续时间点对牙髓测试仪的最大输出无反应，则认为麻醉成功。颊侧浸润麻醉成功率为54%，下牙槽神经阻滞麻醉成功率为43%；差异无统计学意义（p = 0.34）。颊侧浸润麻醉的牙髓麻醉起效明显更快（p = 0.03）。总之，对于下颌第一磨牙，4%阿替卡因颊侧浸润麻醉对临床医生而言可能是一种有用的替代方法，因为与下牙槽神经阻滞相比，其起效更快且成功率相似。
