Nevada Dental Practice Act: Statutory Structure, Definitions, and Scope
Where the rules live
The Nevada Dental Practice Act is NRS Chapter 631, with implementing regulations in NAC Chapter 631. It creates the Nevada Board of Dental Examiners, defines dentistry and dental hygiene, sets licensure, and authorizes discipline. The Act is not a clinical textbook: exam questions test who may do what, under whose authority, and what happens when those limits are crossed.
Key definitions
- Dentistry: diagnosis and treatment of oral disease, surgery, prescribing, and other irreversible care.
- Dental hygiene: preventive and therapeutic services such as prophylaxis, scaling, root planing, polishing, fluoride, sealants, and radiographs when authorized and supervised.
- Supervision: the dentist's authorization and availability; the level (direct, indirect, general) depends on the task and setting.
- Unlicensed practice: performing licensable acts without a Nevada license or outside an exemption.
Scope is task-based. A hygienist may perform hygiene services and additional duties allowed by Board regulation, but may not diagnose, prescribe, or perform irreversible procedures reserved to dentists. Exemptions are narrow-students in accredited programs and certain licensed professionals-and do not create general permission.
Worked example
A patient has swelling and asks the hygienist to prescribe an antibiotic because the dentist is out. The hygienist may document findings and arrange dentist contact, but prescribing is dentistry and outside hygiene scope. Doing it would be unlicensed practice and unprofessional conduct.
Traps
Do not assume 'supervised' means the dentist must always be in the room; the required level matters. Do not treat the Act and regulations as interchangeable: statutes set authority, regulations fill in details. Do not let a clinic policy expand scope.
