Course Description

Theory and clinical application of nitrous oxide sedation for dental patients as prescribed by the State Dental Practice Acts of Oregon, Washington and California.

Addendum to Course Description

Studentswill learn the theory of sedation in a classroom setting and become familiar with the equipment and sedation process in the laboratory. When laboratory competence is achieved, students will use NO2/O2 sedation in the clinic under supervision.

Intended Outcomes for the course

Students will use nitrous oxide/oxygen sedation for dental hygiene treatment in a safe and effective manner under supervision.

Outcome Assessment Strategies

  • Provide sedation to 4 student partners during scheduled lab time.

  • Name all parts of the sedation unit.

  • Complete all assigned reading

  • Prepare complete assessment reports of each sedation session.

  • Process evaluations must be completed satisfactorily for 1 clinic patients receiving sedation.

  • Complete a comprehensive final.

  • Pass a clinical examination.
