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 in Kentucky 201 KAR 8:562E, Section 11).


Upon completion of this course, participants should have an understanding of:

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.
7. Discuss the pharmacology of local anesthetic agents and vasoconstrictors commonly used in dentistry.
8. Calculate the maximum safe dose of local anesthetic agents and vasoconstrictors for individual patients.
9. Describe local and systemic complications that may occur with the administration of local anesthesia.
10. Discuss the management of local and systemic complications that may occur with the administration of local anesthesia.
11. Safely and effectively administer anterior superior alveolar, middle superior alveolar posterior superior alveolar, naso-palatine, greater palatine, inferior alveolar/lingual, long buccal, and mental nerve 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.

In addition, each participant will be required to complete a current medical history form (forms will be provided by the University of Louisville School of Dentistry). Attendance for all class, laboratory and clinical sessions is required. It is suggested that you wear scrubs. No open-toed shoes are permitted in the course.

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 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.

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