Dental Hygienist Licensing Exam · Put your knowledge to work in context.
The National Board Dental Hygiene Examination is the written licensure examination that a graduate of a Commission on Dental Accreditation dental hygiene program must pass before applying for a state or regional license to practice as a registered dental hygienist.
