Dental Practice Act and Board rules governing dental hygiene
This domain tests whether you can locate the legal authority for dental hygiene practice in Louisiana and apply it to supervision and scope questions. The Dental Practice Act, La. R.S. 37:751 et seq., creates the Louisiana State Board of Dentistry and sets the statutory framework; the Board's rules in the Louisiana Administrative Code, Title 46, Part XXXIII, fill in supervision levels, delegated duties, infection control, records, and office standards. Exam items often ask which rule controls, who may perform a task, and what must be documented.
Core rules
- Dental hygiene is a licensed activity. Only a person licensed by the Board may practice dental hygiene or use the protected title.
- The hygienist works under a licensed dentist's authorization. The dentist is responsible for the overall treatment plan; the hygienist may not diagnose, prescribe, or perform irreversible procedures outside the authorized scope.
- Scope includes prophylaxis, scaling and root planing, polishing, topical fluoride, sealants, radiographs, and patient education, but each service must fall within the Board-authorized scope and the applicable supervision level.
- Supervision is not a single standard. Board rules define direct, indirect, and general supervision and may limit certain services or settings. Direct supervision generally requires the dentist to be physically present and available; general supervision generally means the dentist has authorized the service but is not on the premises. Always check the written rule for the specific service and setting.
- Board rules also govern infection control, patient records, advertising, delegation, and inspections. Violating a rule can be unprofessional conduct even if the patient was not harmed.
Worked example
A hygienist at a school-based clinic wants to apply sealants without a dentist on site. The hygienist must first identify the service (sealant), the setting (school clinic), and the Board rule's supervision level for that setting. If the rule permits general supervision with a prior dentist examination and written authorization, the hygienist may proceed and must document the authorization and findings. If the rule requires direct supervision, the hygienist may not proceed merely because a dentist gave a verbal okay. The reasoning is: service + setting + supervision level + documentation.
Traps
Do not treat supervision as one undifferentiated concept. Do not assume public health, school, or nursing-home settings create independent practice. Do not rely on an oral instruction that is not charted. Do not perform an expanded function without the required Board-approved training and permit.
