Montana Dental Practice Act: scope, definitions, and licensing framework
What this domain tests
This domain tests the statutory skeleton of Montana dental hygiene regulation: what counts as dentistry and dental hygiene, who must be licensed, and how the Board of Dentistry fits into the Montana Department of Labor and Industry. The exam favors definitions and jurisdiction over clinical technique.
Core framework
- The Montana Dental Practice Act is codified in Title 37, chapter 4, MCA; Board rules are in ARM Title 24, chapter 138. The Board adopts rules, approves schools, issues licenses, and disciplines licensees.
- A person may not practice dentistry or dental hygiene without a Montana license. A license is personal, nontransferable, and subject to renewal and discipline.
- “Practice of dentistry” includes diagnosis, treatment planning, surgery, prescribing, and procedures on teeth, gums, and supporting structures. “Practice of dental hygiene” is the licensed subset: prophylaxis, scaling, polishing, fluoride, sealants, radiographs, and patient education under the supervision the Board requires.
- Dental assistants may assist but cannot independently perform hygiene services. Expanded functions require the training and supervision the Board authorizes.
Worked example
An unlicensed aide polishes a patient’s teeth and applies fluoride while the hygienist is at lunch. The aide is practicing dental hygiene without a license; the hygienist may also face discipline for aiding unlicensed practice. The fact that the tasks seem “simple” does not create an exception.
Traps
Do not treat “dental assistant” as a mini-hygienist. Do not assume a license from another state authorizes Montana practice. Do not confuse the Board’s rulemaking authority with the Legislature’s authority to define scope.
