The exam outline changed in 2025. The modules mirror the current seven blocks and their weights (35/35/30 by area), so nothing on the blueprint goes uncovered and no time goes to a retired outline.
The clinical-exam waiver, the BLS requirement, the $300 renewal fee, and the 2025 outline all changed since 2022. The prep flags exactly these stale-prep traps so old forum answers do not cost you points.
What's inside
Instead of piecing together the laws book, forum threads, and outdated PDFs, you move through the same blocks the DHBC tests — from informed consent (1A, 20%) through obligations within the professional role (3B, 10%).
| Block | Name | Weight |
|---|---|---|
| 1A | Informed Consent and Patient Rights | 20% |
| 1B | Patient Privacy and Protected Health Information | 9% |
| 1C | Limits to Confidentiality and Mandated Reporting | 6% |
| 2A | Scope of Practice, Professional Conduct, and License Requirements | 20% |
| 2B | Professional Practices | 15% |
| 3A | Obligation to the Patient | 20% |
| 3B | Obligations within the Professional Role | 10% |
Review status, plainly
Every material rule in this product traces to a primary source — the DHBC 2025 Laws and Regulations book, the PSI Candidate Information Bulletin, or the statute it teaches. Mahtab Mansour, DDS reviewed and signed off on this content on July 24, 2026. Her approval is recorded against each file's exact content digest, so any later edit clears it and returns that file to pending review. She is a California dentist, not a hygienist — the standing that matters here is supervising RDHs under these same statutes. Review is not a pass guarantee, and there is none.
