Iowa Code § 153.22
A dentist or dental hygienist who is serving only as a resident, intern, or graduate student and who is not licensed to practice in this state is required to obtain from the board a temporary or special license to practice as a resident, intern, or graduate student. The license shall be designated "Resident License" and shall authorize the licensee to serve as a resident, intern, or graduate student only, under the supervision of a licensed practitioner, in an institution approved for this purpose by the board. Such license shall be renewed at the discretion of the board. The fee for a resident license and the renewal fee shall be set by the board based upon the cost of issuance of the license. The board shall determine in each instance those eligible for a resident license, whether or not examinations shall be given, and the type of examination. None of the requirements for regular permanent licensure are mandatory for resident licensure except as specifically designated by the board. The issuance of a resident license shall not in any way indicate that the person so licensed is necessarily eligible for regular licensure or that the board is obligated to so license the person. The board may revoke a resident license at any time it shall determine either that the caliber of work done by a licensee or the type of supervision being given such licensee does not conform to reasonable standards established by the board.
