(A) Any person is considered to be practicing dental hygiene who engages in those clinical procedures primarily concerned with the performance of preventive dental services not constituting the practice of dentistry, including removing all hard and soft deposits and stains from the surfaces of human teeth, root planing, performing clinical examination of teeth and surrounding tissues, and charting of oral conditions for diagnosis by a dentist, and performing such other procedures as may be delegated by regulations of the board.

(B) In school settings, licensed dental hygienists may apply topical fluoride and may perform the application of sealants and oral prophylaxis under general supervision, with written permission of the student’s parent or guardian.

(C) In hospitals, nursing homes, long term care facilities, rural and community clinics, health facilities operated by federal, state, county, or local governments, hospices, education institutions accredited by the Commission on Dental Accreditation that give instruction in dental hygiene, and in bona fide charitable institutions, licensed dental hygienists may apply topical fluoride and perform the application of sealants and oral prophylaxis under general supervision. Treatment may not occur in these settings unless medical emergency care is available within the facility.

(D) Licensed dental hygienists may provide oral hygiene instruction and counseling, perform oral screenings, and provide nutrition and dietary counseling without prior authorization.

(E) Upon certification by the board and when under the direct supervision of a practicing dentist, a licensed dental hygienist may administer local infiltration anesthesia.

(F) This section is not intended to establish independent dental hygiene practice.

(G) No person other than a licensed dentist or dental hygienist may use the title "dental hygienist", present themselves as being a dental hygienist, or perform oral prophylaxis. This does not preclude an expanded duty dental assistant from polishing restorations and supra-gingival tooth structure. Dental hygienists practicing under general supervision must maintain professional liability insurance.
