The Dentist Is Out of State: Supervision, Authorization, and Local Anesthesia
Dr. Alvarez leaves Thursday morning for a three-day conference in Chicago and will not return to the state until Sunday night. His hygienist, Renee, has been licensed for nine years and holds current certification in local anesthesia. Thursday's schedule includes a 62-year-old new patient referred for a 'deep cleaning' whom Dr. Alvarez has never examined; a recall patient with 6 mm pockets in two quadrants who has asked for anesthesia before her scaling and root planing; and three routine recare appointments. At 8:10 a.m. the office manager tells Renee to 'go ahead and do the doctor's exam on the new patient and chart what needs filling so he can approve it from Chicago.' Dr. Alvarez texts Renee: 'You're covered under my license while I'm gone. Just handle it and I'll sign everything Monday.' No other dentist is on staff or on call, and the practice has no locum agreement in place.
1. May Renee perform the scaling and root planing on the new patient Thursday? Walk through the supervision and authorization analysis and state what she should do with the appointment.

No. Two independent requirements fail.
Authorization rests on a dentist's diagnosis. Scaling and root planing is treatment of periodontal disease. A hygienist may not diagnose periodontal disease or prescribe its treatment; the dentist's order must be grounded in an examination and documented findings. Dr. Alvarez has never seen this patient, so there is no clinical basis in the record for a treatment plan of SRP. An established patient with a documented exam and written treatment authorization may be treated under indirect supervision in the dentist's absence, but a new patient with no dentist examination does not satisfy that threshold.
The text message is not a valid order. 'You're covered under my license' misstates the law: Renee practices under her own hygiene license and is personally accountable for every service she provides. Supervision is a documented relationship, not a verbal or texted assurance, and retroactive sign-off on Monday does not convert Thursday's unauthorized treatment into authorized treatment.
What she should do: convert the visit to what she is authorized to do (health history, radiographs if ordered, periodontal charting, and a prophylaxis only if the record supports it), explain to the patient that the definitive treatment visit requires the dentist's examination, and reschedule the SRP. Document the request, the refusal, and the reason in writing.
2. The recall patient has requested local anesthesia for her SRP. Renee is currently certified. May she administer it Thursday, and what alternatives exist?
Read the worked answer
No. Certification in local anesthesia expands what a hygienist may do; it does not change the supervision level attached to it. In North Carolina, a certified hygienist administers local anesthesia only under direct supervision, meaning the dentist is on the premises and immediately available to respond. Dr. Alvarez is several states away and no other dentist is on site, so the direct-supervision condition cannot be met, regardless of Renee's credentials or the patient's preference.
Alternatives, in order of preference:
- Reschedule the anesthesia visit to a day when the dentist is in the building, and treat the non-anesthesia quadrants as the treatment plan allows.
- If the plan permits, manage the appointment with non-pharmacologic comfort measures and topical anesthetic, and document what was and was not completed.
- Contact the patient in advance so she is not surprised at the chair.
Renee should also confirm that the practice's emergency kit, monitoring equipment, and reversal agents are present and current before any anesthesia appointment, and that the patient's medical history has been reviewed for contraindications. Administering anesthesia without the dentist on site would expose Renee to discipline for practicing outside the authorized supervision level, and would expose the practice as well.
3. Evaluate the office manager's instruction that Renee 'do the doctor's exam and chart what needs filling.' What is within her scope and what is not?
Read the worked answer
The instruction conflates two different activities.
Within scope: collecting and recording data. Health history, vital signs, radiographs ordered by the dentist, periodontal probing and charting, existing restoration charting, caries-risk assessment data, and intraoral findings described objectively. A hygienist is the licensee who often generates most of the record, and doing so competently is part of the job.
Outside scope: diagnosis and treatment planning. Deciding 'what needs filling' is a clinical diagnosis of caries and a decision about restorative treatment. That belongs to the dentist, and a hygienist who labels teeth as needing restoration is diagnosing. Likewise, performing the dentist's comprehensive examination and presenting it as his is a misrepresentation of who rendered the service.
The remote sign-off problem: a dentist may review radiographs and records, but a diagnosis and treatment plan must reflect the dentist's own examination of the patient. 'I'll sign everything Monday' is retroactive authorization, not supervision, and the record would misstate the sequence of events.
Renee should decline clearly, in writing if necessary, and state the reason: she cannot diagnose or perform the dentist's examination, and she cannot create a record that implies he examined a patient he never saw. She can chart objective findings and flag concerns for his in-person examination, which is exactly what the standard of care requires.
