Lecture & Hands-On

Oral Sedation and Nitrous Oxide Sedation

Instructors: Dr. Daniel Haas and Dr. Michelle Wong

April 5–6, 2025

Course Description

Our Oral Sedation and Nitrous Oxide Sedation course is designed to train dentists in minimal sedation and moderate sedation, achieved by oral administration of a single sedative drug, the administration of nitrous oxide-oxygen, or the combination of a single oral sedative drug with nitrous oxide-oxygen. This course meets the requirements of the RCDSO (Standards of Practice – Use of Sedation and General Anesthesia in Dental Practice) as a training program in the aforementioned modalities of sedation.

Course content includes a review of:

  • Minimal Sedation
  • Moderate Sedation
  • Oral sedative pharmacology
  • Oral sedation regimens
  • Nitrous oxide pharmacology
  • Nitrous oxide equipment and administration
  • Monitoring
  • Respiratory physiology
  • RCDSO Guidelines

Participants must pass two multiple choice exams and an airway skills assessment to be considered having successfully completed this course. Course study material will be sent to participants three weeks prior to course start date in preparation for exams. Those who pass all assessments will be considered qualified to administer minimal and moderate sedations as described in the RCDSO standards, by means of nitrous oxide-oxygen, or a single oral sedative, or the combination of these two.

For more information on obtaining authorization to administer sedation, please see RCDSO website (Authorization to Administer Sedation and General Anesthesia).

Medical Emergencies in the Dental Office by Dr. Daniel Haas is a prerequisite for this course.

The course must have been completed within two years prior to taking this Sedation course. It must have been completed in-person (not online). To ensure that the course content meets the necessary requirements, the course must have been taken through Continuing Dental Education (University of Toronto).

  • In order to fully participate in all hands-on sessions, participants must be licensed to practice dentistry in Ontario. Dentists from outside Ontario may still take this course, however they will not be permitted to administer nitrous oxide sedation on a live person. Instead, a demonstration will be provided for such dentists allowing them to become familiar with the complete procedure.

    Dentists from outside Ontario who wish to fully participate in the session involving administration of nitrous oxide sedation on a live person must obtain an Education License/Certificate for the duration of the course (see RCDSO website for further information).

  • Please arrive within 30 minutes before the course start time to sign in.

    Staff will be available at the Faculty of Dentistry’s Edward St entrance to admit participants into the building as this building is not open to the public. If you arrive too early, you may need to wait until staff arrive.
