Illinois Dental Hygienist Practice Act and Rules of the Department
What the exam tests
This domain tests your ability to read and apply the statutory and regulatory framework rather than isolated facts. Questions often turn on definitions, the Department’s rulemaking authority, and the relationship between the Act and the administrative code.
Core rules
- The Dental Practice Act sets the broad statutory framework for dentistry and dental hygiene; the Department adopts detailed rules, including 68 Ill. Adm. Code 1220, covering licensure, supervision, CE, and practice standards.
- The Department administers and enforces the Act, investigates complaints, and may impose discipline. The Board of Dentistry provides advice, but the Department is the licensing authority.
- Definitions in the Act and rules control scope questions: “dental hygiene,” “direct supervision,” “general supervision,” and “public health dental hygienist” have specific meanings.
- Rules can be more detailed than the statute, but a rule cannot expand a statutory prohibition or grant authority the Act does not give.
Worked example
A hygienist argues that because a rule mentions a procedure, she may perform it without a permit. The correct analysis is to check the statute first: does the Act authorize the procedure for dental hygienists, and does it require a permit or supervision? The rule then supplies the details. If the Act requires a permit, the rule cannot be read to eliminate it.
Traps
- Relying on general memory of another state’s dental practice act.
- Assuming the Board of Dentistry, rather than the Department, issues the final license.
- Treating a definition as merely descriptive when it controls scope.
- Ignoring later amendments to the Act or rules.
