Cal. Business and Professions Code § 1647.7

(a) Prior to the issuance or renewal of a permit to administer moderate sedation, the board may, at its discretion, require an onsite inspection and evaluation of the licensee and the facility, equipment, personnel, and procedures utilized by the licensee. The permit of any dentist who has failed an onsite inspection and evaluation shall be automatically suspended 30 days after the date on which the board notifies the dentist of the failure unless, within that time period, the dentist has retaken and passed an onsite inspection and evaluation. Every dentist issued a permit under this article shall have an onsite inspection and evaluation at least once in every six years. Refusal to submit to an inspection shall result in automatic denial or revocation of the permit. (b) An applicant who has successfully completed the course required by Section 1647.3 may be granted a one-year temporary permit by the board prior to the onsite inspection and evaluation. Failure to pass the inspection and evaluation shall result in the immediate and automatic termination of the temporary permit. (c) The board may contract with public or private organizations or individuals expert in dental outpatient moderate sedation to perform onsite inspections and evaluations. The board may not, however, delegate its authority to issue permits or to determine the persons or facilities to be inspected.
