Monitor Nitrous Oxide Inhalation


A registered dental assistant registered with the Board as an RDA may be authorized to monitor nitrous oxide/oxygen inhalation under the direct supervision of a dentist. To utilize the expanded duty an RDA must show proof of training which can be obtained through any one of the following methods:

  •  Successful completion of a Board approved dental assisting program.

  •  A Board approved continuing education course.

  •  Individual training provided by a ND licensed dentist, or

  •  The RDA provides proof of a credential issued by another state for the monitoring of nitrous oxide/oxygen inhalation and the training was substantially equivalent to ND requirements.

An RDA who submits proof of education and training will receive an endorsement on the registration card which provides verification of board approved training. If you have received and submitted proof of training/education, and the endorsement for monitoring nitrous oxide/oxygen is not seen on the registration card, please notify the Board.
