The purpose of this study is to evaluate, with the electric pulp tester, the anesthetic efficacy of the periodontal ligament injection using 2% lidocaine with 1:100,000 epinephrine and saline in human mandibular premolars. The periodontal ligament injection using 2% lidocaine with 1:100,000 epinephrine was found to be an effective technique for anesthetizing mandibular first premolars. However, the duration of profound pulpal anesthesia was approximately 10 minutes. The periodontal ligament injection using sterile saline was not an effective technique for anesthesia. Teeth mesial and distal to the injected tooth may also become anesthetized with this injection technique. The initial needle penetration and injection of the anesthetic solution in clinically healthy teeth were only mildly discomforting. No increase in tooth mobility was observed 45 minutes after the periodontal ligament injection. No clinically observable pulpal or periodontal damage was seen at 3 weeks after the injection.
本研究的目的是使用牙髓电活力测试仪，评估在人类下颌前磨牙中，使用含1:100,000肾上腺素的2%利多卡因和生理盐水进行牙周膜注射的麻醉效果。结果发现，使用含1:100,000肾上腺素的2%利多卡因进行牙周膜注射是麻醉下颌第一前磨牙的有效技术。然而，深度牙髓麻醉的持续时间约为10分钟。使用无菌生理盐水进行牙周膜注射不是有效的麻醉技术。采用这种注射技术，注射牙近中和远中的牙齿也可能被麻醉。在临床健康的牙齿中，最初的进针和注射麻醉溶液只会引起轻微不适。牙周膜注射45分钟后，未观察到牙齿松动增加。注射后3周，未发现临床上可观察到的牙髓或牙周损伤。
