This lecture is designed for dentists and dental hygienists who wish to expand their understanding of the pharmacologic mechanisms and delivery techniques of local anesthesia and to solve some of the difficulties that arise in obtaining profound anesthesia in the oral cavity.

A wide range of both maxillary and mandibular block techniques will be emphasized, as well as the efficient use of infiltration injections. Safe and efficient block techniques for complete quadrant anesthesia of the maxilla and mandible, such as the Gow-Gates mandibular division nerve block and the Greater Palatine Canal maxillary division nerve block techniques, will be emphasized in the context of recognizing and anesthetizing accessory nerve pathways. Use of alternative anesthesia modalities, including: topical anesthetic formulations, the incorporation of an anesthetic buffering system and anesthetic-reversal agent, intraosseous techniques and computerized delivery systems, to obtain either primary or secondary anesthesia will also be presented.

The controversy surrounding the use of articaine and prilocaine for mandibular block anesthesia injections will be addressed, in addition to the management of possible complications and injuries related to the delivery of oral local anesthesia agents, such as hematoma, paresthesia and trismus.

You Will Learn

  • An overview of local anesthesia pharmacology
  • Contraindications and toxic reaction concerns with local anesthetics
  • The potential interactions of patient medical conditions with local anesthetics
  • Review of oral anesthesia nerve pathways, accessory innervation pathways, and their management
  • Review of all conventional local anesthesia injections, infiltration versus block injections: what to use when
  • Alternative mandibular anesthesia injection techniques, including the Gow-Gates and Vazirani-Akinosi quadrant blocks
  • Comparison of alternative with conventional techniques
  • Reasons for failure to obtain anesthesia and problem solving these failures
  • Unexpected side effects and their management, hematomas and nerve injuries
  • Anesthetic reversal and buffering agents

Who Should Attend

Dentists and dental hygienists will return to their practices with greater confidence in their ability to deliver comfortable and efficient local anesthetic injections.
