ADEX Dental Hygiene Exam Price

The adex dental hygiene exam is a national licensure examination administered by the Commission on Dental Competency Assessments (CDCA). It is required for hygienists to practice in 46 states. The ADEX exam is a two-hour computer simulated clinical exam that tests 100 multiple-choice questions. It uses simulated patients, radiographs, study model images and laboratory data to test your knowledge of dental hygiene.

The NBDHE is the standard examination for licensure of dental hygienists in most states. It is an evaluation of the basic dental hygiene science, clinical practices and responsibilities, community health and research applications.

The CITA - ADEX examination consists of two components: the Computer Simulated Clinical Examination and the Patient Treatment Clinical Exam. Each component requires a passing score of 75% or greater.

Candidates for licensure in this state must pass a written and clinical examination before they can apply for a license. The written exams are offered on-line and are in two subject areas: infection control/sterilization and North Carolina jurisprudence. The ADEX or CITA clinical dental hygiene exam must also be passed.

Once you obtain your dental hygiene license, you will need to renew it on a yearly basis. The process is similar to other types of professional licenses. You will need to submit a renewal fee, a statement that you have completed the required continuing education, a CPR card and other documents as needed.
