The term "Practice of Dentistry" includes the practice of dentistry under a restricted faculty license. The term "Practice of Dentistry" does not include:
"Community-based Clinic" means an organized clinic offering primary health services to low-income individuals or to residents in medically underserved areas or health professional shortage areas. The term includes a State health center, nonprofit community-based clinic and a federally qualified health center.
A "Dental Hygienist" is one who is legally licensed as such by the State Board of Dentistry to perform those educational, preventive, and therapeutic services and procedures that licensed dental hygienists are educated to perform. Licensed dentists may assign to dental hygienists intra-oral procedures which the hygienists have been educated to perform and which require their professional competence and skill but which do not require the professional competence and skill of the dentist. Such assignments shall be under the supervision of a licensed dentist. Such performance of intra-oral procedures by licensed dental hygienists shall be in the private office of a dentist or public or private institution such as prescribed under section 11.9(b). Dental hygienists certified as public health dental hygiene practitioners may perform intra-oral procedures without the assignment of a dentist pursuant to section 11.9. The foregoing shall not be construed as authorizing the assignment of diagnosing, treatment planning and writing prescriptions for drugs or writing authorizations for restorative, prosthetic, or orthodontic appliances. The board shall issue rules setting forth the necessary education and defining the procedures that may be performed by dental hygienists licensed under this act including those procedures that may be performed under direct and general supervision.
The word "board," as used in this act, means the State Board of Dentistry.

An expanded function dental assistant may, under direct supervision, perform those procedures specified in section 11.10 and other reversible procedures not designated by this act to be performed by licensed dentists or dental hygienists. For purposes of this definition, "direct supervision" shall mean that a dentist is in the dental office or treatment facility, personally diagnoses the condition to be treated, personally authorizes the procedure and remains in the dental office or treatment facility while the procedure is being performed and, before dismissal of the patient, personally evaluates the work performed.
