The Expanded-Function Question at a Rural Clinic
Marisol, RDH, has practiced for six years in a small southern Arizona town where the nearest dentist is 40 minutes away. Her supervising dentist, Dr. Okafor, has treated a patient, Mr. Vance, for a decade and has signed a written order for a prophy and fluoride varnish. Mr. Vance misses his dental home regularly and now presents with mild gingival inflammation but no bleeding on probing beyond two isolated sites. Dr. Okafor is out of the office for two weeks at a conference, and the patient asks whether Marisol can complete the appointment today. Marisol holds a current Arizona license and a current local anesthesia certificate. The practice has no standing delegation agreement on file, and the office manager suggests Marisol simply proceed because "the doctor always orders this."
1. Can Marisol complete the prophylaxis and fluoride varnish today under Arizona law? Identify what she must verify before proceeding and what she should do if the verification fails.

Marisol's authority is bounded by the Arizona Dental Practice Act and the Board's rules. A hygienist practices under the supervision level the statute assigns to each procedure, not under generalized office custom. Before treating, she must confirm three things: (1) that her license is active and not restricted, (2) that the specific procedures (prophy, fluoride varnish) fall within the delegated scope and the supervision level actually satisfied by Dr. Okafor's written order, and (3) that the order is current, patient-specific, and documented. A vague "the doctor always orders this" is not a substitute for a valid order. If the order is stale, unsigned, or not patient-specific, she should not proceed. She should contact Dr. Okafor (or the covering dentist) to obtain a compliant order, or reschedule. Proceeding without a valid order risks discipline for practicing outside supervision requirements, and the office manager's suggestion does not insulate her.
2. The office manager argues that because the patient is a long-standing patient, the doctor's prior orders create an ongoing authorization. Evaluate that argument and explain what documentation Marisol should create either way.

The argument fails. Prior orders do not create open-ended authority; each order must be current and tied to the treatment being rendered. A long-standing relationship does not expand the statutory supervision level or substitute for a valid order. Even if Dr. Okafor had given a broad standing instruction, the Board expects patient-specific documentation and compliance with the applicable supervision category. Marisol should document: the date and content of the order she relied on, the dentist who issued it, the procedures performed, the supervision level she believed applied and why, and any communication with the dentist. If she declines to treat, she should document the reason for deferral and the rescheduling plan. This record protects the patient and demonstrates good-faith compliance if the Board later reviews the encounter.
3. Suppose Marisol proceeds and the Board later opens an investigation. What categories of unprofessional conduct or grounds for discipline are most likely implicated, and what mitigating facts would matter?
Read the worked answer
The likely theories are practicing outside the scope or supervision level authorized by law and failing to comply with documentation requirements. Depending on the facts, the Board could also consider aiding unlicensed or unauthorized practice if she allowed unqualified staff to perform parts of the appointment. Mitigating facts include: a genuine, reasonable belief that a valid order existed; prompt self-reporting; cooperation with the investigation; remedial training; and absence of patient harm. Aggravating facts include ignoring a clear warning from the office manager's own words, prior discipline, or falsifying records to create a retroactive order. Marisol should retain counsel, respond truthfully, and avoid altering records after the fact, since record alteration itself is independent grounds for discipline.
