The Short-Staffed Day: Delegation to an Uncredentialed Assistant
Kim is one of two hygienists in a four-chair practice owned by Dr. Patel. The other hygienist calls in sick and the schedule is packed: eight patients, four of them booked for scaling and root planing. The office manager, acting on Dr. Patel's instruction, tells Brittany, a dental assistant with six months of on-the-job training and no formal credential or expanded-function course, to 'start the SRP in operatory 3 with the ultrasonic and place sealants on the two kids in operatory 1, since Dr. Patel signed their charts last week.' She then tells Kim to 'keep an eye on Brittany between your own patients and sign her notes as the provider so it's clean.' Dr. Patel is in operatory 4 preparing a crown and says through the wall, 'You're the licensed one out there, Kim, it's fine, we always do this when we're slammed.' Kim's first patient is already seated and the ultrasonic is already running in operatory 3.
1. May Brittany legally perform the scaling and root planing with the ultrasonic? Identify the violations and Kim's personal exposure.
Read the worked answer
No. Scaling and root planing, including ultrasonic instrumentation, is limited to licensed dentists and licensed dental hygienists. It is not an expanded function that can be delegated to unlicensed assistive personnel under any supervision level, and a dentist's signature on last week's chart does not create authority for an unlicensed person to treat.
Violations in play:
- Unlicensed practice of dental hygiene by Brittany.
- Aiding and abetting unlicensed practice by anyone who directs, permits, or assists it, including Kim if she participates or stands by as the 'supervisor.'
- Falsification of the clinical record if Kim signs notes as the provider for treatment she did not render. Records must identify who actually performed each service; a false attribution is a record-keeping violation independent of the delegation problem.
- Failure of supervision by the owner-dentist, who cannot satisfy his supervisory duties from another operatory while unlicensed personnel treat patients.
Kim's exposure is personal. 'The doctor told me to' and 'we always do this' are not defenses; her license is on the line for every patient in that chair. The practical step is an immediate, clear refusal, in writing, with the reason stated: Brittany is not licensed to scale, and Kim will not supervise or sign for it. The schedule should be reworked, not the license.
2. Does the analysis change for the sealants on the two children? Explain how delegation of expanded functions actually works in North Carolina.
Read the worked answer
It changes, but not enough to make the current plan lawful.
North Carolina does permit certain expanded functions to be delegated to dental assistants who have completed the required Board-recognized training or certification, and sealant placement is one of the functions that may fall in that category. The delegation is lawful only when all of the following line up: the assistant holds the required credential or completed the required course; the function is one the rules allow to be delegated; the patient has been examined and the treatment authorized by the dentist; and the correct level of supervision is in place.
Brittany meets none of the credentialing elements. Six months of on-the-job training with no formal course does not create expanded-function authority, and no amount of clinical aptitude substitutes for it.
The second error is structural: delegation runs from the dentist to the assistant. A hygienist is not a substitute supervising licensee who can launder an assistant's expanded-function work into compliance, and Kim cannot convert an uncredentialed assistant into a credentialed one by watching. The children's sealants should wait for a qualified provider or be done by Dr. Patel or Kim herself, which is squarely within hygienist scope.
3. Kim refuses. What should she document, and what should she do if Dr. Patel overrides her and proceeds anyway?
Read the worked answer
Documentation first, because the record is what a Board investigator will read.
- Note in writing, contemporaneously, what she was asked to do and what she declined, with the date and time. A brief email to herself or a dated memo is enough; it does not belong in the patient's clinical note.
- State the specific reason: Brittany is not licensed to scale, and I will not supervise unlicensed scaling or sign another provider's notes.
- Do not sign anything she did not do. If a note appears under her name later, correct it immediately in writing and keep a copy.
If Dr. Patel proceeds anyway and unlicensed scaling occurs, Kim is a licensee with knowledge of conduct that endangers patients. Most boards expect a licensee who cannot stop the conduct internally to report it. Before that step she should escalate inside the practice: state the problem directly to the owner-dentist rather than through the office manager, and put the concern in writing so there is a record that she objected.
She should also protect her own position: confirm the patients were treated by a qualified provider, and if they were not, ensure the treating dentist is told so a clinical assessment can be made. Participation, silence in the chart, or a signature on a false note turns a bad day for the practice into a disciplinary case for her.
