This course is designed to review the knowledge and skills necessary to effectively administer block and infiltration anesthesia, as well as nitrous oxide analgesia. The course will include classroom, laboratory, and clinical instruction. Participants will work in groups of two or three and administer local anesthesia and nitrous oxide analgesia on each other. The Kentucky Board of Dentistry has approved this course for (6) CEUs in local anesthesia (3 hours didactic and 3 hours clinical) and (2) CEUs in nitrous oxide sedation (1 hour didactic and 1 hour clinical). Upon successful completion of this course, participants will have completed the educational requirements for local anesthesia and nitrous oxide credentialing under course KBD #0089.



IMPORTANT: Attendees will be required to wear a mask when not eating or drinking. Additionally, attendees will be required to provide proof of full COVID-19 vaccination status OR proof of a negative COVID-19 diagnostic test (PCR only) administered no more than 72 hours prior. A photo or copy of documentation is acceptable.

Course Objectives

  1. Determine the medical risk of administering a local anesthetic or nitrous oxide to a patient as well as the contraindications based on the patient's medical problems.
  2. Locate hard and soft tissue landmarks associated with the various local anesthetic injections.
  3. Describe the neuro-anatomy of the trigeminal nerve.
  4. Identify and assemble the armamentarium necessary for the administration of local anesthesia.
  5. Demonstrate correct use of local anesthetic armamentarium.
  6. Identify nerve, teeth, and soft tissue structures anesthetized with specific injections.

  12. Differentiate between anesthesia and analgesia.
  13. Discuss the pharmacology of nitrous oxide/oxygen conscious sedation.
  14. List the beneficial and adverse effects of nitrous oxide/oxygen conscious sedation.
  15. Identify the contraindications for nitrous oxide/oxygen conscious sedation.
  16. Identify and demonstrate the use of equipment/armamentarium for nitrous oxide/oxygen conscious sedation.
  17. Describe the three phases in administering nitrous oxide/oxygen conscious sedation.
  18. Safely and effectively administer nitrous oxide/oxygen conscious sedation.

*Important Course Information:

Attendance for all class (online) and clinical (ULSD) sessions is required.

Each participant will be expected to be both an operator and patient, unless a medical condition precludes the safe administration of local anesthesia. If you are unable to participate as a partner during the clinical portion, you must provide a replacement.

Each participant is expected to professionally contribute to the course. This is demonstrated by attending class, being on time, being prepared (coming to class with an awareness of the subject under discussion, wearing appropriate clinical attire, appropriately disinfecting, setting up and breaking down the operatory, following required infection control guidelines, evaluating medical histories of clinical partners, recording legal progress notes, etc.) and contributing to the class discussion.

Each participant must demonstrate competent administration of nitrous oxide sedation and local anesthesia for each of the stated injections according to state regulations.


Webinar: The online portion of this course will be presented through Microsoft Teams (Teams). ULSD CE will send instructions closer to the course date on how to log into Teams to participate. Attendees are not required to have a camera on their computer. You will need to be able to hear the lecture and ask questions either through a microphone on your computer or by dialing in on your phone.
