DANB CRFDA case studies
DANB CRFDA · Put your knowledge to work in context.
The CRFDA is a dental assisting credential administered by the Dental Assisting National Board (DANB). The acronym is variously expanded as Certified Radiologic Health and Safety Dental Assistant and Certified Restorative Functions Dental Assistant, and the two expansions point to different bodies of knowledge - radiation safety and restorative chairside procedures - so confirm the exact scope with DANB before you build a study plan. DANB's homepage describes its certification portfolio as spanning "all stages of your career, from entry level to advanced," and presents certification as a way to "show your commitment and demonstrate your knowledge." DANB's site navigation lists exam preparation resources including study guides, online proctored exams, test center exams, state exams, and Spanish-language exams, and it directs candidates to the DALE Foundation for online practice tests and review courses. DANB also publishes state requirements covering job levels, exam and education pathways, and allowable duties, which matters because permitted radiologic and restorative duties are set at the state level. The DANB CRFDA case studies are 5 cases and about 2,116 words.
