The Dentist Steps Out: Sorting a Recall Afternoon by Supervision Level
Marcy, RDH, works in a two-chair general practice in Ames. On Thursday the dentist, Dr. Okafor, leaves at 1:00 p.m. for a regional dental meeting 25 minutes away and will not return until 4:30. The afternoon schedule is: 1:30 - recall prophy and bitewings for a patient Dr. Okafor examined 11 months ago; there is no written order in the chart. 2:00 - new patient, age 34, chief complaint "my back tooth aches when I drink cold water," who has never been examined by Dr. Okafor. 3:20 - scaling and root planing for a patient with 6–7 mm pockets that Dr. Okafor diagnosed last week, with a signed order in the chart; the patient has asked for "numbing" and Marcy holds the Board's local anesthesia permit. At 1:50 Dr. Okafor texts: "New patient is fine, just do the prophy and tell her to schedule a filling. Call me if anything looks weird."
1. Sort the three afternoon patients into permitted and not permitted, naming the supervision category that applies to each and the documentation that must support it.

1:30 recall, established patient. This is general supervision territory - the dentist has authorized hygiene care but is not physically present. General supervision still requires that the dentist has examined the patient and authorized the service within the lookback period the Board's rule sets, and that the authorization is in the record. The 11-month-old exam may be outside that window, and there is no order in the chart. Marcy should not simply proceed because the patient is "established." She should get a documented, contemporaneous verbal order (record the date, time, who gave it, and what was authorized) or confirm the exam date satisfies the rule; otherwise reschedule.
2:00 new patient. Not permitted. A hygienist cannot initiate care on a patient the dentist has never examined, and a text message is not an examination. "Tell her to schedule a filling" is a diagnosis and treatment plan, which belongs to the dentist.
3:20 SRP. Permitted under general supervision - the dentist diagnosed the condition and left a signed order. The local anesthesia is not. Anesthetic infiltration requires direct supervision, meaning the dentist must be physically present; a phone call or text does not convert general supervision into direct supervision.
2. What is the correct response to Dr. Okafor's 1:50 text, and what must Marcy do about the 2:00 patient, who is in pain and cannot return for two weeks?

She should reply in writing, briefly and factually, that she cannot begin care on a patient the dentist has never examined and cannot supply a diagnosis or treatment plan by text, and ask him to return, refer, or authorize a specific next step. The exchange should be saved or summarized in the chart - texts about patient care are part of the record and may be discoverable.
For the patient: pain plus a cold sensitivity complaint is a triage problem, not a hygiene problem. Marcy may take a limited history, record vital signs if appropriate, give no diagnosis, and offer concrete options - an exam slot when Dr. Okafor returns, an exam with another dentist in the practice, or referral to a dentist or urgent care clinic that can see the patient sooner. She must not tell the patient what is wrong or what treatment she needs. If the patient declines every option, document the advice given, the patient's refusal, and the recommended follow-up. Declining to treat without arranging an alternative is the beginning of an abandonment problem; a documented referral is the defense.
3. The 3:20 patient is already anesthetized from a previous visit and says "just do it, I'll sign anything." Marcy is tempted to proceed with the SRP and skip the infiltration. What should she consider?

Two separate questions are being blended. First, can the SRP legally proceed? Yes - general supervision, signed order, dentist's diagnosis on file. Second, is it clinically and ethically appropriate to begin definitive periodontal therapy on residual anesthesia from an earlier appointment? That is a clinical judgment, and the safe answer is no: anesthesia from an earlier visit is not a valid basis for a lengthy SRP appointment, and a patient cannot consent her way around a supervision requirement. If the patient needs anesthesia, the appointment moves to a time when the dentist is on site and direct supervision exists. If she proceeds without anesthesia, the informed-consent conversation must cover discomfort and the option to reschedule, and that conversation belongs in the note. "I'll sign anything" is exactly the moment to slow down: document what was explained, what the patient chose, and why. And a blanket waiver signed to get out the door is not informed consent.
