This study was undertaken to investigate whether plain lidocaine, 3% plain mepivacaine and 3% prilocaine with felypressin were suitable epinephrine-free local anesthetic solutions for use in periodontal ligament anesthesia as alternatives to lidocaine with 1:80,000 epinephrine. Two hundred and seven patients received one of the four test solutions via a periodontal ligament injection and the success rate of anesthesia was confirmed using an electric pulp stimulator. Although neither mepivacaine nor prilocaine were as effective as lidocaine with epinephrine, the success rates of these three solutions were not statistically different. A single periodontal ligament injection of any of the solutions tested resulted in a low incidence of anesthesia. The success rate of lidocaine without epinephrine was consistently poor.
本研究旨在调查单纯利多卡因、3%单纯甲哌卡因和含肾上腺素的3%丙胺卡因是否适合作为不含肾上腺素的局部麻醉溶液用于牙周膜麻醉，以替代含1:80,000肾上腺素的利多卡因。207例患者通过牙周膜注射接受四种测试溶液中的一种，并使用牙髓电刺激器确认麻醉成功率。虽然甲哌卡因和丙胺卡因都不如含肾上腺素的利多卡因有效，但这三种溶液的成功率在统计学上没有差异。对任何一种测试溶液进行单次牙周膜注射导致麻醉发生率较低。不含肾上腺素的利多卡因成功率一直很低。
