Two Supervisory Worlds in One Week
Renata, RDH, has six years of clinical experience. Monday and Wednesday she works in a four-chair general practice under general supervision: her dentist examined most patients within the past eleven months, is reachable by phone, but spends two days a week at a second office 25 minutes away. On Fridays she is contracted by a nonprofit to treat residents at a 68-bed assisted living facility and second-graders at a Title I elementary school. Neither site has a dentist on site; a dentist of record signed a collaboration agreement but has never examined any resident. In one Friday she is asked to (1) apply fluoride varnish and place sealants on 19 second-graders; (2) scale a 74-year-old resident whose HbA1c is 9.4% and who has a 2 cm white patch on the buccal mucosa; and (3) give a new resident a quick look and chart 'no decay' so the family can skip a dental appointment. That evening her private-practice employer texts that he will be late Tuesday and asks her to 'just do the injections' for two patients.
1. Sort the four requests (varnish/sealants, scaling the resident, the 'quick look,' the injections) into within scope, within scope only if conditions are met, and outside scope. State the test you applied.

Test applied - three separate questions, not one. (a) Is the procedure listed in the hygienist's statutory and regulatory scope? (b) Does the setting and supervision level match what that procedure requires? (c) Does an extra Board permit or authorization attach? Confirm the current text of M.G.L. c. 112 and 234 CMR rather than relying on a remembered list.
- Varnish and sealants (19 children): core hygiene/preventive functions, and public health and school settings are where unsupervised hygiene practice is most often authorized. But authorization depends on the site qualifying and Renata holding whatever public health designation the Board requires. Sealants also normally presuppose a dentist's diagnosis or an approved screening protocol - she cannot invent the indication.
- Scaling the resident: scaling is within scope, but the setting and her supervisory status must permit it, and the 2 cm white patch plus HbA1c 9.4% generates a referral duty, not a hygiene judgement call.
- 'Quick look - no decay': diagnosing the absence of disease is the practice of dentistry. Outside scope regardless of setting.
- Injections: local anesthesia is permit-based and carries its own supervision requirement. A text from an employer creates no authority.
2. What must Renata confirm about supervision before Tuesday in the private office, and before Friday at the two public health sites?
Read the worked answer
Private office (general supervision). General supervision usually means the dentist has examined the patient and authorized hygiene treatment within a defined look-back period, and remains reachable for consultation. Renata should pull the definition from the current regulations and compare it to the eleven-month figure. If the interval has run, the patient is no longer 'under general supervision' for that purpose and she should not proceed until the dentist examines or the rules are satisfied. 'Reachable by phone, 25 minutes away' is a separate question - check whether the rule requires physical presence or only availability for the procedures she plans.
Public health sites. Do not assume that absence of a dentist equals autonomy. She needs: written confirmation the site is a qualifying setting; the scope of the dentist-of-record agreement; a documented referral pathway and emergency plan; informed consent procedures that work for a school child and for a resident with possible cognitive impairment; and a plan for transferring records. The fact that the dentist of record has never examined any resident is the weak link - find out whether the arrangement permits that, and what triggers a required dental examination. Get the answers in writing before Friday.
3. Draft the substantive content of the record entries and communications for the resident with the white patch and the child whose parent declines a referral.

White patch, 74-year-old, HbA1c 9.4%. The note should be factual and non-diagnostic: size, location, appearance, duration if known, whether it blanches or is fixed, any associated findings, and the fact that it was not present/known previously if true. Record that she advised the resident and, with consent, the responsible family member or facility nurse, that a dentist must evaluate it, and the referral made with date. Record the diabetes discussion: elevated HbA1c raises periodontal risk and healing concerns, but she is not adjusting the patient's medical management. Avoid 'lesion is benign' or any diagnostic label.
Declined referral, child. Document what was recommended, that the parent or guardian declined, who was told, and what return precautions were given. A refusal is not the end of the duty: note whether an alternate pathway (school nurse, primary care, community clinic) was offered.
Both entries should be contemporaneous, signed, and legible, because they are the evidence if the Board or a plaintiff later asks what she saw and what she did about it.
