The Six-Month Recall That Wasn't
Dr. Alana Reyes, DDS, holds an active Arkansas dental license and practices in Little Rock. Her hygienist, Brandi, RDH, has been licensed for four years. On a busy Tuesday, Dr. Reyes is simultaneously running two operatories and finishing a crown prep when Brandi asks whether she can place a subgingival local anesthetic for a scaling and root planing appointment on a 34-year-old patient with no medical contraindications. Dr. Reyes, hands occupied, says 'sure, go ahead' without leaving the room. Later that week, a patient of record calls complaining of pain after a filling and asks the front desk to have 'the assistant' call in a five-day supply of hydrocodone/acetaminophen. The front desk also mentions that a new patient scheduled next week wants a cleaning only and refuses an exam, stating she 'just needs the tartar off.'
1. Evaluate whether Brandi may administer local anesthesia in this scenario under Arkansas dental law. What supervision level is required, and what did Dr. Reyes do wrong?
Read the worked answer
Arkansas law permits a licensed dental hygienist to administer local anesthesia only under direct supervision of a licensed dentist, meaning the dentist must be physically present in the office and evaluate the patient before the procedure. A general 'go ahead' issued while the dentist is occupied in another operatory does not satisfy the pre-procedure evaluation requirement. The correct practice is for Dr. Reyes to examine the patient, confirm the anesthesia plan, and remain on-site and available during administration. Dr. Reyes's failure to evaluate the patient before authorizing the injection is a supervision deficiency and exposes her to disciplinary action for aiding unlicensed or improperly supervised practice. Brandi is also responsible for confirming she is practicing within the authorized scope and supervision level before proceeding.
2. Can the dental assistant call in the hydrocodone prescription? Explain the prescribing rules implicated.
Read the worked answer
No. Prescribing authority rests with the licensed dentist. A dental assistant cannot transmit an oral prescription for a controlled substance, and a dentist cannot delegate the decision to prescribe. The dentist must personally evaluate the patient, determine that the prescription is within the scope of dental practice, and either issue or authorize the prescription. Hydrocodone is a Schedule II opioid, and Arkansas imposes additional requirements: the prescriber must be registered with the Arkansas Prescription Drug Monitoring Program, query the PDMP before prescribing an opioid, and comply with limits on the quantity and duration of opioid prescriptions for acute dental pain. The front desk's request to have the assistant 'call in' the prescription reflects a delegation that is not permitted under the Dental Practice Act.
3. How should the office respond to the new patient who wants a cleaning without an exam?
Read the worked answer
The office should decline to provide hygiene services without a dentist's examination. In Arkansas, a dental hygienist may provide services only as part of a dentist's treatment plan and under the required supervision. A prophylaxis or scaling without an examination and diagnosis by the dentist would exceed the hygienist's authorized role in a traditional private practice setting and would violate the standard of care. The appropriate response is to explain that an examination is required to establish a diagnosis, identify contraindications, and develop a treatment plan before any hygiene treatment. If the patient refuses, the office may decline treatment, but should document the refusal and offer the exam.
