About Course #L0758

Release Date: July 11, 2016

Expiration Date: December 31, 2019

The ability to obtain profound local anesthesia is essential for the successful completion of restorative procedures as well as for the success of oral surgery, periodontal surgery, and endodontic procedures. However, local anesthesia is not always initially successful. There is a high rate of failure with the conventional inferior alveolar nerve block, a technique in which teeth of the right or left mandible are anesthetized for dental procedures. The indirect and direct techniques that are most commonly employed to locate the inferior alveolar nerve are ineffective in achieving complete mandibular anesthesia in approximately 15% to 30% of cases.

This basic-level course describes periodontal ligament injection techniques for administering local anesthetics to provide pulpal anesthesia when conventional infiltration and regional block methods are unsatisfactory or inadequate. The indications and contraindications for periodontal ligament injections are discussed in addition to factors influencing the duration and efficacy of periodontal ligament anesthesia and potential postoperative side effects.
