Dentistry: Louisiana Licensure, Scope, and Professional Responsibility
What this domain tests
The Dentistry domain tests the dentist’s legal duties under the Louisiana Dental Practice Act (La. R.S. 37:751 et seq.) and Louisiana State Board of Dentistry rules. Expect licensure, scope of practice, delegation and supervision, prescribing, records, infection control, advertising, continuing education, and discipline. The exam asks who may do what, under whose authority, and who remains responsible.
Core rules
- The Board licenses dentists, dental hygienists, and expanded-duty dental assistants, investigates complaints, and may impose discipline.
- A dentist diagnoses, treatment-plans, prescribes, and performs surgical and prosthetic procedures. Other tasks may be delegated only when Board rules authorize them and the auxiliary holds the required license or certification.
- Supervision is not a transfer of liability. The dentist remains responsible for delegated care and must ensure the supervision level required by rule.
- Prescribing requires a valid dentist-patient relationship and a documented evaluation. Staff may not prescribe or renew controlled substances.
- Keep contemporaneous records: history, findings, diagnosis, treatment, consent, medications, referrals, and delegation/supervision. Records must be accurate and retained as Board rules require.
- Advertising must not be false or misleading. Infection control must follow Board-adopted standards, generally CDC guidance.
Worked example
An established patient calls two days after an extraction with swelling and fever. The dentist is out of town. A hygienist offers to call in amoxicillin “to save time.” Correct analysis: the hygienist may not prescribe. The dentist must personally evaluate or arrange appropriate coverage; if a prescription is issued, it must rest on a valid relationship and documented assessment. The dentist cannot avoid responsibility by saying the hygienist acted independently.
Traps
Assuming one supervision definition fits every task. Treating delegation as transferring legal responsibility. Letting unlicensed staff diagnose or prescribe. Using boilerplate consent without documenting the discussion. Ignoring Board continuing-education and renewal requirements until licensure lapses.
