Frequently Asked Questions

What are the three dental hygiene licensure categories in California?

California licenses three categories: RDH (Registered Dental Hygienist), RDHAP (Registered Dental Hygienist in Alternative Practice) who can practice with direct access in community settings, and RDHEF (Registered Dental Hygienist in Extended Functions) who can perform additional restorative procedures.

How is the California dental hygiene law and ethics exam structured?

The exam consists of 60 multiple-choice questions (50 scored, 10 pilot/unscored) to be completed in 60 minutes. A passing score requires getting 38 of the 50 scored questions correct (75%). The exam is computer-based and administered at PSI testing centers.

What is an RDHAP and how does it differ from an RDH?

An RDHAP (Registered Dental Hygienist in Alternative Practice) can practice with direct access in settings like nursing homes, schools, and residences without direct dentist supervision. RDHAPs must have a bachelor's degree, 2,000 hours of clinical experience, and complete a 150-hour RDHAP program.

What are the California dental hygiene CE requirements?

California dental hygienists must complete 25 CE hours every 2 years. Of those, a minimum of 2 hours must be in infection control and 2 hours in the California Dental Practice Act. Up to 12.5 hours may be completed through home study.

Which board regulates dental hygienists in California?

The Dental Hygiene Board of California (DHBC) is the separate regulatory board for dental hygienists. Unlike most states where a single dental board regulates both dentists and hygienists, California has a dedicated board for dental hygiene at 2005 Evergreen Street, Suite 1350, Sacramento, CA 95815.
