The School Sealant Program: Public Health Supervision Limits
Marcus is a hygienist with five years of clinical experience who wants to run a school-based program at a rural Title I elementary school with 400 students. Roughly 60 percent of the children have no dental home and the nearest dentist is 40 minutes away. His plan: two days of visual screenings, sealants on permanent first molars, fluoride varnish, and 'a quick scaling for the kids whose gums bleed.' No dentist will be on site. A dentist friend who lives 90 minutes away told him verbally, 'You're covered, do what you need to do.' The school sent home a letter saying 'unless you opt out, your child will receive dental services.' On day one, a second-grader presents with swelling of the right cheek and a temperature of 101.5 degrees Fahrenheit. A parent also asks Marcus to 'pull the wiggly tooth and clean her teeth while you're in there.'
1. What legal authority must be in place before Marcus treats any child? Evaluate the verbal approval and the opt-out consent letter.
Read the worked answer
School-based care without a dentist on site is possible only under the public health supervision pathway, and that pathway has conditions. Marcus needs, at minimum:
- An approved setting. The statute and rules identify the settings where public health supervision applies. A school program generally fits, but the setting must actually qualify.
- A written agreement with a supervising dentist. A verbal 'you're covered' from a friend 90 minutes away does not satisfy this. The agreement should name the services authorized, the record-keeping and periodic record-review arrangement, and the referral and follow-up process.
- Demonstrated clinical experience. The pathway requires a minimum period of clinical practice before a hygienist may work without a dentist's prior examination; Marcus should confirm he meets it.
- A referral and follow-up system. Children with findings must be connected to a dental home, with documentation that the referral was made and tracked.
On consent: a blanket opt-out letter is a weak basis for sealants and varnish. Informed consent for a clinical service should be affirmative, in writing, and describe the specific services, the risks and benefits, and what happens with the findings. An opt-out form may be acceptable for screening in some programs, but it is not a substitute for treatment consent.
He should not begin until the written agreement, the experience verification, and the affirmative consent process are in place.
2. Sort the planned services: which are within scope under public health supervision, and which are not? Include the parent's request.

Within scope, if the pathway conditions are met:
- Visual screening. Screening identifies children who need care; it is not diagnosis. Marcus records what he sees, states clearly that it is a screening and not a diagnosis, and refers.
- Sealants on permanent molars, with written consent, proper isolation, and documentation of tooth selection and retention checks.
- Fluoride varnish, with consent and documentation.
Outside scope:
- 'A quick scaling for the kids whose gums bleed.' Scaling and root planing treats periodontal disease that a dentist has diagnosed. Bleeding gums in children commonly reflect plaque, eruption, or poor technique, not periodontitis. Performing SRP on screening findings is treatment without diagnosis, and it is not authorized on a public health basis. The correct action is hygiene instruction, referral, and re-screening.
- Extracting the 'wiggly tooth.' Extractions belong to the dentist, including primary teeth that appear ready to exfoliate. A tooth that is actually loose may still have roots, and removal by a hygienist is outside scope and a real risk of injury.
His answer to the parent should be simple and non-defensive: the tooth is the dentist's to evaluate, here is the referral, and here is what can be done today.
3. The child with facial swelling and a fever: what are Marcus's obligations, and what must he avoid doing?
Read the worked answer
This is a dental emergency, not a screening finding, and the response is triage and referral.
What he must avoid:
- Do not treat it. No incision and drainage, no packing, no prescription or dispensing of antibiotics, no 'let me just clean around it.' All of that is outside hygiene scope and dangerously inadequate for a spreading infection.
- Do not send the child back to class with a note and no plan.
- Do not attempt to manage it by phone advice to the parent.
What he must do, in order:
- Recognize the red flags: facial swelling, fever, and the possibility of trismus, difficulty swallowing, or eye involvement, any of which indicate a spreading infection that needs urgent care.
- Notify the school nurse and the guardian immediately, describe the findings in plain language, and state that the child needs to be seen today.
- Arrange a same-day referral to a dentist or urgent care setting, with the practice name, address, and phone number in writing.
- Document the objective findings, the time of the conversation, who was contacted, what was recommended, and the referral given.
- Follow up within 24 to 48 hours and document the outcome.
If the guardian cannot be reached, he should escalate through school administration so the child is not released without a plan. His obligation is not to fix the infection; it is to make sure the child is seen and that the record shows he acted.
