The Lapsed DA II and the Saturday Impression
Dr. Alvarez owns a two-chair general practice in Hickory. On a busy Saturday the only clinical staff are Jordan, a DA I, and Morgan, a DA II whose Board registration lapsed 47 days ago because she never submitted renewal paperwork; her CDA certification is current. The 9:00 patient, a 34-year-old with a symptomatic upper first molar, is scheduled for a final impression and fluoride varnish after a temporary crown was placed. Dr. Alvarez has a 10:15 lease signing two blocks away and tells Morgan, 'Go ahead and take the final impression, place the matrix, and apply the varnish; I'll be back by 10:40.' Morgan has performed these steps many times. The patient is not told the dentist will be out of the office. At 9:50 the patient's husband asks Jordan whether the dentist is in the building, and Jordan says he stepped out. The office has no written supervision policy, and Morgan's renewal packet is still on the front desk.
1. Was Morgan permitted to perform the assigned steps while Dr. Alvarez was off premises? Analyze the supervision category and the registration defect.
Read the worked answer
No. In North Carolina, expanded functions assigned to a DA II, including taking a final impression, placing a matrix, and applying fluoride varnish, must be performed under direct supervision. Direct supervision requires the dentist to be physically on the premises, to have personally examined the patient before treatment, and to remain available to evaluate the patient and the work; being reachable by phone is not enough. Dr. Alvarez left the building, so the arrangement was at most general supervision, which does not authorize these delegated acts. Separately, Morgan's lapsed Board registration means she could not lawfully perform DA II functions during the 47-day gap; a current CDA alone is insufficient. The dentist's instruction therefore created two violations: unauthorized expanded-function practice and use of an unregistered assistant. Morgan's experience and the dentist's plan to check the bite later do not cure either defect.
2. What should Dr. Alvarez do now, and what disciplinary exposure does he face?
Read the worked answer
He should immediately stop delegating expanded functions to Morgan, verify her registration status, and refuse to backdate or 'fix' the renewal. He should document the event, disclose the supervision lapse to the patient, notify his malpractice carrier, and consider a fee adjustment. Self-reporting to the Board before a complaint arrives is generally mitigating. Exposure includes discipline for aiding unregistered practice, failing to supervise, and possibly unprofessional conduct; sanctions can range from a reprimand and civil penalty to probation with practice monitoring. Morgan also faces discipline for practicing without current registration. The office needs a written supervision policy, a credential-expiration tracking system, and staff training. The Board will focus less on the 20-minute absence than on the complete absence of a supervision system.
3. If Dr. Alvarez had stayed in the building but remained at the front desk, would the delegation have been lawful?

Closer, but not automatically. Direct supervision has both a location element and a clinical-evaluation element. Being in the building at the front desk can satisfy physical presence and availability, but only if the dentist actually examined the patient beforehand and can promptly evaluate the impression and tissue. If the dentist never sees the patient before the procedure or cannot leave the desk to assess the result, the Board may find that supervision was nominal rather than direct. For a stable patient and a routine impression, documented pre-operative examination and prompt post-operative review might support direct supervision. The prudent course is to remain in the clinical area, define in writing when the dentist may be out of the operatory, and require a documented handoff before any expanded function begins.
