DANB CDA Exam Study Guide 2026-2027, Certified Dental Assistant GC RHS ICE, 200 Practice Questions, Dental Assisting Test Prep PDF

Prepare for all three DANB® Certified Dental Assistant (CDA®) component exams with one complete study guide: General Chairside Assisting (GC), Radiation Health and Safety (RHS), and Infection Control (ICE). The content review follows DANB's official exam outlines domain by domain, and the radiography review is fully digital, matching the current RHS exam.

The two 100-question practice tests are weighted like the real exams (GC, RHS, and ICE in the same 95/75/75 proportion). They use chairside, imaging, and infection-control scenarios, image-error corrections, sterilization logs, and OSHA situations, with four answer choices like the real exams. Every answer comes with an explanation.
