Restricted Permit II

Important Information About the Restricted Permit II

A Restricted Permit II allows you to induce conscious sedation by nitrous oxide inhalation.

If you hold a Restricted Permit II, you are not allowed to induce the following:

  • deep sedation
  • general anesthesia.

Before applying for a permit for sedation or anesthesia, it is imperative for you to thoroughly review Section 7.0 of the Rules and Regulations of the Delaware Board of Dentistry and Dental Hygiene. The Board’s rules define conscious sedation, deep sedation and general anesthesia using definitions adapted from the American Dental Association.

If you are applying for a Restricted Permit II, you must fully understand the difference between conscious sedation and deep sedation. The educational requirements for deep sedation and general anesthesia are much more stringent than for conscious sedation. This distinction is important both from the standpoint of this permit application and from the standpoint of clinical practice.

A patient who is given an intravenous drug is in a state of deep sedation if he or she loses either the ability to respond rationally to command or any protective reflexes at any time during the procedure.

    • Examples of “third-party forms” are transcripts from schools, employment verifications from a supervisor, and license verifications from another state.
  • Forms requiring a supervisor signature, seal, or notary may have to be MAILED to the Board office directly UNLESS the document specifically indicates to UPLOAD the document.
