About this exam
The DANB Certified Dental Assistant (CDA) Examination is a national certification examination for dental assistants in the United States. It assesses knowledge used in a dental office; it is not an entrance exam or a process for selecting candidates for dental school. Candidates pursue the CDA credential to demonstrate professional knowledge across the certification’s component exams: General Chairside (GC), Radiation Health and Safety (RHS), and Infection Control (ICE). Eligibility depends on DANB’s current requirements and the candidate’s qualification pathway, so review the official DANB information before applying.
CDA exam preparation should cover the content areas for all three components, including chairside procedures, dental anatomy and tooth identification, patient medical histories, and infection prevention. Review oral pathology, standard precautions, and the safe processing, sterilization, and disinfection of dental instruments as well. The exam is delivered in a computer-based format, and details such as application requirements and scheduling can change. For the 2027–2028 cycle, use DANB’s current candidate materials as the authority, then build a study plan around the published outlines and the topics you find most challenging.
How to prepare for the DANB CDA Examination
- Use DANB’s current exam outlines to organize separate review for General Chairside, Radiation Health and Safety, and Infection Control; check the official eligibility and application requirements before scheduling.
- Review dental anatomy, tooth identification, oral pathology, medical histories, and chairside assessment alongside standard precautions and instrument reprocessing. Connect each topic to safe, routine dental-office decisions.
- Use timed question practice to identify weak areas, then review why each answer is correct or incorrect. Avoid relying only on memorized answers; return to the relevant concepts and official candidate materials.
