DANB CRFDA study guide
DANB CRFDA · Work through your exam, one topic at a time.
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. Topics on this exam: Restorative Functions - Unverified (source unavailable). The DANB CRFDA study guide has 1 section and about 606 words.
01Restorative Functions: Isolation, Matrix/Wedge, Amalgam and Composite Placement, Finishing
The Restorative Functions domain of the DANB CRFDA exam tests the chairside skills an expanded-function dental assistant uses during direct restorative procedures: field isolation, matrix and wedge placement, amalgam and composite handling, carving and contouring, finishing/polishing, and occlusal verification. The published outline for this domain could not be independently verified here, so the content below reflects standard, widely taught restorative-assistant practice. Your state's scope of practice and your dentist's written protocol always govern what you may perform. The rubber dam remains the reference standard for operative isolation; verify the seal with an explorer and floss ligatures, and confirm no leakage before the dentist begins.
