Time: 8:00 am - 11:30 am Code: F07 Cost: $30/$45 after Sept. 28 Date: Friday

CE Credits: 3 hour lecture  |  Subject: Local Anesthesia |  Recommended for: Dentists, Hygienists

This lecture is for those who wish to expand their understanding of the pharmacologic mechanisms of local anesthesia and to solve some of the difficulties that arise in obtaining profound anesthesia in the oral cavity. How do local anesthetic agents work for dentistry, and why don’t they always work? Simple calculations for maximum safe dosage levels and possible contraindications and interactions of local anesthetic solutions with patient medical conditions and medications are presented. The controversy surrounding the use of articaine (Septocaine) and prilocaine (Citanest) for block anesthesia injections will be addressed, and management of possible complications and injuries related to the delivery of oral local anesthesia agents, such as hematoma, paresthesia, and trismus, will be discussed. A wide range of techniques will also be presented, including the Gow-Gates mandibular block and methods for addressing hot tooth/hot gums situations. Alternative anesthesia modalities, including topical anesthetic formulations, buffering and reversal agents, and more! This course combines the latest innovations in local anesthesia with the best of newer techniques for delivery.

Learning Objectives:

  • Discuss the mechanisms and clinical importance of local anesthetic uptake and binding.
  • Discuss advantages and disadvantages for use of the available local anesthetic agents with and without vasoconstrictor additives.
  • Discuss potential adverse reactions to local anesthetics, such as syncope, allergy, and toxicity, and how to minimize the risk of adverse reactions.
  • Have a thorough understanding of the pharmacology of available local anesthetic agents, including their advantages, disadvantages, and safety profiles.
  • Be better able to assess and manage complications that may occur in the delivery of local anesthesia, and be better able to avoid them when possible.
  • Discuss the science and effectiveness of anesthetic delivery techniques and a rational approach to selecting the best technique(s) for different patient care situations.
  • Apply the latest anesthetic agent technology to their daily practice and describe the latest trends in achieving profound patient comfort.
