Missouri Dental Practice Act and Board Rules
What this domain tests
This domain tests how well you understand the statutory and regulatory architecture of Missouri dental practice: Chapter 332, RSMo (the Dental Practice Act), and the Missouri Dental Board rules in 20 CSR 2110. Questions often ask who has authority, what a definition controls, and whether a rule violation is independently disciplinable.
Core rules and concepts
- The Dental Practice Act creates the Missouri Dental Board and gives it authority to license, examine, adopt rules, investigate complaints, and discipline licensees. The Division of Professional Registration handles administrative functions, but the Board exercises professional judgment.
- Statutory definitions control scope. If conduct falls within the statutory definition of dentistry, only a licensed dentist may perform it or delegate it as the Act and rules allow.
- Board rules have the force of law. A licensee can be disciplined for violating a rule even if the statute does not separately name the conduct.
- The Act distinguishes dentists, dental hygienists, and dental assistants. Assistants are not licensed as dentists or hygienists, and any permitted duties depend on specific rule authorization.
Worked example
An unlicensed aide uses an ultrasonic scaler to remove calculus from a patient. The dentist is in the building and says the aide was “supervised.” The Board can proceed against the dentist for aiding unlicensed practice and for allowing a person not authorized to perform scaling to do so. Supervision does not create authority; the task must be delegable to that category of personnel, and the aide must hold any required permit. The dentist’s presence is not a defense.
Traps that cost marks
- Treating Board rules as advisory “guidelines” rather than enforceable law.
- Assuming “direct supervision” lets any employee perform any procedure.
- Confusing the Board with the Division, or assuming a state license elsewhere authorizes Missouri practice.
- Ignoring the statutory definition and relying on office custom.
