D. In addition to performing dental hygiene as defined in Subsection B of this section, dental hygienists who have met the criteria as the committee shall establish and the board shall ratify may administer local anesthesia under indirect supervision of a dentist. E. The board may certify a dental hygienist to administer local anesthetic under the general supervision of a dentist if the dental hygienist, in addition to performing dental hygiene as defined in Subsection B of this section: (1) has administered local anesthesia under the indirect supervision of a dentist for at least two years, during which time the dental hygienist has competently administered at least twenty cases of local anesthesia and can document this with a signed affirmation by the supervising dentist; (2) administers local anesthetic under the written prescription or order of a dentist; and (3) emergency medical services are available in accordance with rules promulgated by the board. F. A dental hygienist: (1) may prescribe, administer and dispense a fluoride supplement, topically applied fluoride or topically applied antimicrobial only when the prescribing, administering or dispensing is performed: (a) under the supervision of a dentist; (b) pursuant to rules the board and the committee have adopted; (c) within the parameters of a drug formulary approved by the board in consultation with the board of pharmacy; (d) within the parameters of guidelines established pursuant to Section 61-5A- 10 NMSA 1978; and (e) in compliance with state laws concerning prescription packaging, labeling and recordkeeping requirements; and (2) shall not otherwise dispense dangerous drugs or controlled substances. G. A New Mexico licensed dental hygienist may be certified for collaborative dental hygiene practice in accordance with the educational and experience criteria established collaboratively by the committee and the board.

J. An expanded-function dental auxiliary may perform other related functions for which the expanded-function dental auxiliary meets the training and educational standards established by the board and that are not expressly prohibited by the board. K. For the purpose of this section, "collaborative dental hygiene practice" means the application of the science of the prevention and treatment of oral disease through the provision of educational, assessment, preventive, clinical and other therapeutic services as specified in Subsection B of this section in a cooperative working relationship with a consulting dentist, but without general supervision as set forth by the rules established and approved by both the board and the committee.
