Board exams for Oklahoma licensure

Every state requires the written National Board Dental Hygiene Examination (NBDHE). For the hands-on clinical exam, Oklahoma accepts ADEX or CRDTS.

ADEX

The American Board of Dental Examiners (ADEX) exam. It was formerly given through CDCA-WREB-CITA, which included WREB and CITA.

CRDTS

The Central Regional Dental Testing Service exam. SRTA has merged into CRDTS.

Our dental hygiene board exam guide covers how the NBDHE works, how it's scored, and how to study.

Jurisprudence exam and local anesthesia

Jurisprudence exam
Required

Oklahoma tracks local anesthesia as an advanced procedure on your license. You apply separately, and a local anesthesia exam may be required.

Moving to Oklahoma with a license from another state

Oklahoma is one of 13 states that have enacted the Dentist and Dental Hygienist Compact. Oklahoma enacted the compact on May 13, 2026, as the 13th state, and the law takes effect November 1, 2026. Once the compact commission starts issuing privileges, a hygienist licensed in one member state will be able to practice in the others. It isn't issuing them yet.

If you're already licensed in another state, ask the Oklahoma Board of Dentistry about licensure by credentials (also called endorsement or reciprocity). Our guide to getting a dental hygiene license explains how it usually works.
