RDH exam prep

California RDH Law & Ethics Prep

California-specific prep for the DHBC Registered Dental Hygienist (RDH) Laws and Ethics Written Examination — statute-cited, current, and built for the 2025 exam outline.

This prep is for Registered Dental Hygienist (RDH) candidates taking the Dental Hygiene Board's Law and Ethics exam — a separate exam from the dentist one. Preparing for the dentist exam instead? Use California Dental Law & Ethics Exam Prep.

Honest review status: every module cites the statute, regulation, or official document it teaches. Source-cited, and every in-scope file carries a current exact-digest sign-off by Mahtab Mansour, DDS on 2026-07-25. The recorded reviewer is a dentist, not a registered dental hygienist or hygiene educator, so role-specific pedagogy review by an RDH or RDHAP is not complete. See how Dentovio verifies content.

Untimed

Question 1 of 15

An adult patient agrees to quadrant scaling and root planing after the dentist's diagnosis. The hygienist explains the procedure, and the patient signs the office consent form — but no one mentions that root sensitivity and gingival recession commonly follow. The patient later sues, saying she would have chosen differently had she known. How would California law most likely characterize that claim?

Statute-cited, not summarized lore

Every rule in the modules cites the section it comes from — the Dental Hygiene Practice Act, 16 CCR Division 11, or the DHBC's own publications — so you can verify anything in the free official laws book.

Keyed to the 2025 outline

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.

Current where it counts

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

Everything is organized around the official 2025 outline.

Instead of piecing together the laws book, forum threads, and outdated PDFs, you move through the same blocks the DHBC tests — from informed consent (1A, 20%) through obligations within the professional role (3B, 10%).

Review status, plainly

Source-cited, and reviewed within a stated scope.

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. Source-cited, and every in-scope file carries a current exact-digest sign-off by Mahtab Mansour, DDS on 2026-07-25. The recorded reviewer is a dentist, not a registered dental hygienist or hygiene educator, and no RDH or RDHAP has reviewed the role-specific pedagogy. Review is not a pass guarantee, and there is none.

Product FAQ

California RDH Law & Ethics Prep, answered

What does California RDH Law & Ethics Prep include?

Statute-cited study modules mirroring the seven blocks of the DHBC's official 2025 examination outline, a question bank with answer rationales, a full-length practice exam, and quick-review sheets — all in one account.

How much does it cost?

A one-time $99. Finish the free practice test first and the price is $89 instead. Access to the study materials is provided for 180 days from the date of purchase.

Has a credentialed reviewer signed off on this content?

Source-cited, and every in-scope file carries a current exact-digest sign-off by Mahtab Mansour, DDS on 2026-07-25. Every rule also traces to a primary source — the DHBC 2025 Laws and Regulations book, the PSI Candidate Information Bulletin, or the statute it teaches. The recorded reviewer is a dentist rather than a hygienist, so this is professional dental and legal-context review, not role-specific hygiene pedagogy review. Review is not a pass guarantee.

Is Dentovio affiliated with the DHBC or PSI?

No. Dentovio is an independent publisher. It is not the Dental Hygiene Board of California, PSI, or an official government service, and all practice questions are original exam-style material — never recalled exam items.

Does Dentovio guarantee I will pass?

No. Dentovio makes no pass guarantee and no outcome promise. The Board's latest complete-year figure is a 70% pass rate for FY2024-25; what the prep adds is current, statute-cited material keyed to the 2025 outline so you are not studying stale rules.
