Public Health Supervision Status in a Private Practice
Dr. Alvarez owns a private general dental practice in Bangor. His hygienist, Kelsey, RDH, holds a Maine public health supervision designation; she is not an independent practice dental hygienist (IPDH). Dr. Alvarez is leaving for a 12-day trip, and no other dentist has agreed to cover the practice. Kelsey has scheduled a 68-year-old patient with type 2 diabetes, probing depths of 6 to 8 mm with bleeding on probing, and a mobile maxillary lateral incisor. Kelsey plans to perform full-mouth scaling and root planing and to place a locally delivered minocycline microsphere. She asks whether her public health supervision status permits her to treat the patient in the private office while Dr. Alvarez is away. The office manager confirms the practice has no written supervision agreement with another dentist and that Kelsey's certificate lists only school and nursing-home settings. The patient is not in acute pain and has no swelling or fever.
1. May Kelsey perform the planned scaling and root planing in the private office while Dr. Alvarez is away? Explain the supervision analysis.

No. The key is that public health supervision is setting-limited, not a general authorization to practice without a dentist. Maine's public health supervision pathway lets a hygienist deliver specified hygiene services in identified public health settings-typically schools, nursing homes, and similar sites-under a written protocol with a dentist. A private dental office is not one of those settings, and Kelsey's certificate itself lists only school and nursing-home sites.
Private-practice hygiene in Maine requires dentist supervision under the Board's supervision rules. Because Dr. Alvarez will be absent and no covering dentist has a written supervision arrangement, Kelsey lacks the required supervision. Her status as a public health hygienist does not convert into an IPDH license; those are separate credentials with separate requirements. The correct step is to reschedule non-urgent care until a supervising dentist is available or to refer the patient.
2. Does the planned placement of a locally delivered minocycline microsphere change the answer? Why or why not?

It reinforces the answer. Even if the scaling and root planing might fall within hygiene scope under proper supervision, placing a locally delivered antimicrobial is a dental procedure, not a hygiene service. It requires a dentist's diagnosis, order, and supervision, and in many settings the dentist performs or directly supervises it.
A hygienist cannot expand her scope by combining an in-scope service with an out-of-scope one. The Board looks at each component of treatment. Because the microsphere placement is outside Kelsey's authorization in this setting, the entire planned appointment cannot proceed as designed while Dr. Alvarez is away. The patient should be scheduled when a dentist is present, or the dentist should arrange a covering dentist with a written supervision agreement.
3. The patient calls back the next day with facial swelling and a temperature of 101.8°F. What should Kelsey do, and what should she document?
Read the worked answer
This is now an urgent situation, but urgency does not create independent practice authority. Kelsey should not initiate treatment on her own. She should arrange immediate evaluation by a dentist-Dr. Alvarez's covering arrangement, an urgent care dental practice, or the patient's physician if dental access is not immediate-and advise the patient to seek emergency care for swelling with fever.
Documentation should include the time of the call, the reported temperature and swelling, the advice given, the referral destination, and that the patient was told to seek urgent care. The record should also show that Kelsey did not provide treatment outside her supervision status. If the patient cannot reach a dentist, direction to a hospital emergency department is appropriate because facial swelling with fever can indicate a spreading infection.
