The Saturday Hygiene Column: Delegation to an Unlicensed Assistant
Dr. R practices general dentistry in Tulsa with two hygienists and three dental assistants. On a busy Saturday, one hygienist calls in sick. Dr. R asks a dental assistant who has five years of chairside experience and a current radiography permit to “run the hygiene column.” The assistant is scheduled to see six recall patients, take bitewing radiographs, perform scaling and root planing on two adults with 5–6 mm periodontal pockets, and place sealants on a 9-year-old. Dr. R is treating patients in the adjacent operatory and looks into the hygiene room for about 30 seconds between his own procedures. The assistant has never received formal training in scaling and root planing, and no dentist is physically present in the room during that procedure. A patient later complains that the “hygienist” seemed unsure and that her gums bled for two days. The Board opens a complaint inquiry and asks Dr. R to explain the delegation.
1. Which of the scheduled tasks, if any, could lawfully be delegated to this assistant in Oklahoma, and what facts control the answer?

The controlling question is not the assistant’s years of experience; it is whether the Board’s rules assign the task to a licensed dentist or dental hygienist, or instead permit delegation to a dental assistant under a specified level of supervision. Exposing radiographs is commonly within an assistant’s scope if the assistant holds the required radiography credential and the dentist meets the supervision rule. Sealants may be delegable in some settings, but only if the assistant has the specific training or certification the rule requires and the dentist has examined the patient. Scaling and root planing is periodontal therapy and part of the practice of dental hygiene; an unlicensed assistant cannot perform it merely because a dentist is nearby. The 30-second check does not convert an unauthorized procedure into authorized treatment. Dr. R must compare each task against the current Board rule, not office custom.
2. What supervision level does Oklahoma law likely require for these tasks, and how does Dr. R’s arrangement fail that standard?
Read the worked answer
Supervision categories matter. Direct supervision generally means the dentist is on the premises, has examined the patient, and authorizes or observes the procedure; general supervision means the dentist authorized the service but need not be present. Dr. R is in the building, but he has not examined each hygiene patient for scaling and root planing, is not in the room, and is not observing the procedure. Even if radiographs or sealants could be delegated at a lower supervision level, the assistant must still hold the required credential and the dentist must satisfy the rule’s examination and authorization conditions. For scaling and root planing, no level of supervision makes the assistant’s performance lawful because the task itself is reserved to a licensed hygienist. The arrangement therefore fails both as a supervision problem and, for the two periodontal patients, as unlicensed practice by the assistant.
3. What professional-discipline exposure does Dr. R face, and what should he do when contacted by the Board?
Read the worked answer
Dr. R faces potential allegations of aiding and abetting unlicensed practice, failing to supervise, and unprofessional conduct. The Board may also examine whether records accurately identify who performed each service and whether the patient was informed. Dr. R should respond to the Board promptly and truthfully, retain all appointment, radiograph, and treatment records, and not alter the chart after the complaint. He should provide the delegation policy, the assistant’s training and credential documents, and a written corrective plan. He should not ask staff to describe the assistant as a hygienist or backdate supervision notes. Because discipline can affect licensure and malpractice coverage, he should consult counsel, but counsel does not excuse delay or record alteration. A credible response acknowledges the specific tasks that should have been rescheduled or referred and shows how future delegation will be checked against the Board’s rules.
