Five Hygienists, One Absent Dentist, and a Weekend Certificate
Dr. R owns two offices and employs five hygienists at the main office. On Thursday, Dr. R is scheduled at the satellite office and no dentist will be on site at the main office. Hygienist A asks the front desk to book three patients: (1) Mr. P, a new patient with 6-mm pockets and heavy calculus, for "a deep cleaning" - he has never been examined by Dr. R; (2) Mrs. L for a final impression for a 3-unit bridge; and (3) Mr. T for "a bite adjustment" on a night guard that feels high. Hygienist A recently completed a weekend course and states she is "certified" to do all three and to inject lidocaine for Mr. P's scaling.
1. Which of the three requested services may a Florida-licensed dental hygienist legally perform here, and why?
Read the worked answer
None of the three, as framed.
- Mr. P's "deep cleaning." Scaling and root planing is within the dental hygiene scope of practice, but only when it is prescribed by a dentist based on the dentist's own examination and periodontal diagnosis. A hygienist may not diagnose periodontal disease, may not decide on her own that 6-mm pockets require SRP, and may not treat a patient the dentist has never examined. The full periodontal charting may be gathered, but the diagnosis and treatment plan are the dentist's.
- Mrs. L's final impression for a bridge. A final impression for a fixed prosthesis is an irreversible, restorative step that is part of the practice of dentistry, not dental hygiene. Out of scope.
- Mr. T's bite adjustment. Occlusal adjustment requires diagnosis of the occlusion and alteration of a restoration - practice of dentistry. Out of scope.
- Injecting lidocaine requires specific authorization and direct supervision; a weekend certificate does not expand the statutory scope of practice.
Rule of reasoning: scope of practice is set by statute and Board rule, not by a course certificate, an employer's policy, or a dentist's permission.
2. Separately from scope, what is wrong with the staffing and supervision plan for Thursday, and what are the compliant options?
Read the worked answer
Two independent problems:
Supervision numbers. Florida limits how many dental hygienists a single dentist may supervise at one time (four). Five hygienists at one location under one dentist exceeds that ceiling, regardless of how the schedule is arranged.
Absent dentist / supervision level. A hygienist practices only under the supervision of a licensed dentist, and the level of supervision required depends on the procedure. Procedures requiring direct supervision cannot be performed while the dentist is at another office. Additionally, hygiene services must be authorized by a dentist following an examination - a new patient cannot receive definitive hygiene treatment before the dentist has examined and diagnosed.
Compliant options: assign a second dentist to the main office for Thursday; reduce the main-office hygiene schedule to no more than the permitted number under one supervising dentist; reschedule the new-patient SRP until after Dr. R's exam and documented perio diagnosis; and return the bridge impression and night-guard adjustment to Dr. R's own restorative schedule.
3. If Hygienist A proceeds anyway, how should the conduct be characterized for each licensee?
Read the worked answer
- For the hygienist: providing services beyond the dental hygiene scope and without required supervision is a practice violation supporting discipline under s. 466.028, F.S. Performing acts that constitute the practice of dentistry without a dental license also implicates the unlicensed-practice provisions of s. 466.026, F.S. - a serious charge, not a paperwork error.
- For Dr. R: permitting an unlicensed or out-of-scope person to perform dental procedures, and failing to supervise adequately, are independent grounds for discipline (aiding unlicensed practice / permitting a violation of the chapter), even though Dr. R was not present.
- For the practice: the office's fee for the impression and the bite adjustment was generated by work the hygienist cannot lawfully perform - a billing and recordkeeping exposure layered onto the licensure exposure.
Judgment point: the exam tests whether you separate scope (what a hygienist may ever do) from supervision (who must be present when she does it) from count (how many she may supervise). All three failed here, and each fails independently.
