Dental Practice Act and Scope of Practice
The dental practice act is the statute that creates the dental board, defines the practice of dentistry, and authorizes discipline. This domain tests whether you can separate statute from board rule, match procedures to the correct provider and supervision level, and spot unlawful delegation in a staffing scenario.
Statutory architecture
- The legislature delegates police power to the board; board rules must remain within the statute.
- “Practicing dentistry” generally includes diagnosis, treatment planning, surgery, prescribing, and holding out as a dentist.
- Unlicensed practice and aiding unlicensed practice are separate violations; the supervising dentist can be disciplined for both.
- Corporate-practice limits prevent a non-dentist owner from controlling clinical judgment.
Supervision and delegation
Most acts define direct, indirect, general, and public-health supervision. Direct means the dentist is physically present; indirect means prior authorization plus availability; general means standing protocols without a prior exam. Expanded-function assistants may perform only reversible, board-listed procedures after approved training.
Worked example
A hygienist performs initial periodontal charting and scaling while the dentist is at a second office. The rule requires direct supervision for initial nonsurgical periodontal therapy. The hygienist is licensed and the patient consented, but the supervision element still fails. The dentist faces improper-delegation exposure, not just the hygienist.
Traps
- Treating ADA policy or CDC guidance as the legal standard; only the act and board rules bind licensure.
- Blurring supervision categories; general supervision is not the same as no supervision.
- Assuming that a licensed provider may delegate anything within their own scope.
- Missing the corporate-practice issue when a non-dentist manager directs treatment.
Exam focus
Read the fact pattern for who examined the patient, who was physically present, and what the board rule actually says.
