N.C. Gen. Stat. § 90-30.1
The North Carolina Board of Dental Examiners may establish by regulation reasonable education, training, and equipment standards for safe administration and monitoring of general anesthesia and enteral and parenteral sedation for outpatients in the dental setting. Regulatory standards may include a permit process for general anesthesia and enteral and parenteral sedation by dentists. The requirements of any permit process adopted under the authority of this section shall include provisions that will allow a dentist to qualify for continued use of enteral sedation, if he or she is licensed to practice dentistry in North Carolina and shows the Board that he or she has been utilizing enteral sedation in a competent manner for the five years preceding January 1, 2002, and his or her office facilities pass an on-site examination and inspection by qualified representatives of the Board. For purposes of this section, oral premedication administered for minimal sedation (anxiolysis) shall not be included in the definition of enteral sedation. In order to provide the means of regulating general anesthesia and enteral and parenteral sedation, including examination and inspection of dental offices involved, the Board may charge and collect fees established by its rules for each permit application, each annual permit renewal, and each office inspection in an amount not to exceed the maximum fee amounts set forth in G.S. 90-39.
