37-4-408. Auxiliary personnel -- employment, duties, and limitations. A dental auxiliary is a person other than a licensed dental hygienist employed by a licensed dentist. The board may, within the limitations of this chapter, adopt rules that define the qualifications and outline the tasks of any unlicensed auxiliary personnel to be employed by a licensed dentist, except that this section may not be construed to allow the board by rule to permit a licensed dentist to delegate to any auxiliary personnel prophylaxis or any of the duties prohibited to dental hygienists under 37-4-401. The performance of intraoral tasks by all dental auxiliaries, as permitted by board rules, must be under the direct supervision of a licensed dentist.
