Abstract: | 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. |
