This online course provides students with an awareness of the indications and contraindications for nitrous oxide use, a working knowledge of the equipment, an understanding of the procedure for administering nitrous oxide analgesia, and preparation to monitor nitrous oxide analgesia inhalation in a dental office. Coursework is completed online through directed text readings along with evaluation measures and completion of clinical skills within the student’s dental office under the supervision of a dentist. The applicant must be currently employed in a dental office where this function is conducted. This course may be taken independently or with the full EFDA course. Upon acceptance into this course, the student will be emailed information on scheduling a required orientation meeting with an instructor. Once the orientation is complete, the student will be approved to begin the coursework and they will have 6-months to complete the readings, evaluation measures, and clinical documentation sheets. There will be on-line quizzes and a final test to complete the course. Iowa Dental Board-approved Continuing Education Hours (CEHs) will be awarded along with a certificate of completion.
