Failure to achieve anesthesia can be a significant problem in the day-to-day practice of dentistry. The usual strategy following an anesthetic failure is to reinject. Therefore, a good understanding of conventional anesthetic techniques is important. But the practitioner also needs to have a broad armamentarium of injection strategies available for the "difficult-to-anesthetize cases". These strategies include the use of 5 percent lidocaine, intrapulpal injection, periodontal ligament injection and intraosseous injection. This paper will be a brief discussion of those techniques with an emphasis on the intraosseous injection.
在牙科日常诊疗中，麻醉失败可能是一个严重问题。麻醉失败后通常的策略是再次注射。因此，深入了解传统麻醉技术很重要。但从业者还需要具备一系列广泛的注射策略，以应对“难以麻醉的病例”。这些策略包括使用5%利多卡因、牙髓内注射、牙周膜注射和骨内注射。本文将简要讨论这些技术，重点是骨内注射。
