Scope of Practice and Licensure Under the Arizona Dental Practice Act
The statutory frame
Arizona dental practice is governed by statute (the Dental Practice Act, A.R.S. Title 32, Chapter 11) and by rules adopted by the Arizona State Board of Dental Examiners. The Act defines the practice of dentistry broadly: diagnosis, treatment planning, surgery and adjunctive treatment of oral disease, and the fitting or dispensing of prostheses. Candidates should know that the definition is functional - what matters is whether an act falls within the statutory description, not the title of the person performing it.
Licensure categories and supervision
Distinguish the licensed dentist, the dental hygienist, and the dental assistant, and know that hygienists and assistants practice under levels of supervision defined in statute and rule (direct, indirect, general, and public health settings). A recurring trap is assuming an unlicensed assistant may perform an irreversible or diagnostic procedure. Irreversible procedures and final diagnosis remain with the dentist; expanded functions for assistants and hygienists require the specific statutory authorization and, where required, Board-recognized training or certification.
Traps in questions
Watch for items that mix up "may perform" with "may perform independently," or that confuse a general supervision setting with direct supervision. Also expect questions on unlicensed practice, practice on a lapsed license, advertising under a license not held, and the treatment of a patient by a licensee whose license is suspended.
Rule of thumb
When an item describes a task, ask two questions in order: (1) Is this act within the statutory definition of dentistry? (2) If yes, does this licensee have the statutory authority to perform it at this supervision level? If either answer is no, the conduct is outside scope.
Worked example
An item states that a certified dental assistant places a final restoration while the dentist is in another operatory and available. The act is restorative and irreversible; the assistant's authority is limited to the functions specifically delegated by statute and rule, and the described act exceeds that authority regardless of the dentist's availability. The correct answer rejects the conduct.
