What primary legal documents define the scope of practice and permissible activities for dental hygienists in Louisiana?

• A. The Federal Dental Practice Act
• B. The Louisiana Public Health Act
• C. The Louisiana Dental Practice Act and the Louisiana Administrative Code provisions that implement it
• D. The Louisiana Dental Hygiene Guidelines

Answer: (C)

The scope of practice for Louisiana dental hygienists is defined by a combination of state law and implementing rules. The Louisiana Dental Practice Act sets the licensing framework and broad boundaries for what dental hygienists may do, while the Louisiana Administrative Code provisions that implement that Act dial in the specific procedures, supervision requirements, and professional standards that govern daily practice. Federal acts and other state health statutes don’t establish Louisiana’s practice scope for dental hygienists, and guidelines issued by agencies are useful for interpretation but are not the binding instruments that define permissible activities. Together, the Act and the Administrative Code provide the authoritative framework and concrete rules for what dental hygienists can perform, such as prophylaxis, radiographs, topical fluoride applications, sealants, and related duties outlined in the code.
