2 credits
This course is designed to fulfill the requirements of Local Anesthesia Instruction set forth by the Washington Revised Code 18.29 for Dental Hygienists. In this course, the student is instructed in the techniques and usage of local anesthesia administration and nitrous oxide sedation. Additionally, the pharmacology of the drugs administered, their interactions with other medications, emergency procedures, and the review of anatomy and physiology of the head and neck will be covered.

Prerequisites: Graduate from an accredited Dental Hygiene School, successful completion of the National Board for Dental Hygienists.
