Certified Dental Assistant (DANB CDA) Prep

Master infection control, radiation health and safety, and general chairside assisting to achieve DANB CDA credentialing.

This comprehensive preparation program aligns directly with the Dental Assisting National Board (DANB) Certified Dental Assistant (CDA) examination blueprints across the RHS, ICE, and GC component exams. Learners master infection prevention protocols, diagnostic imaging techniques, chairside four-handed dentistry, and emergency management practices through evidence-based clinical instruction. Designed for career advancement, the curriculum equips prospective dental assistants with the theoretical knowledge and practical competencies necessary to pass all three exam components on the first attempt. Every lesson includes tutor notes, a video, a hands-on lab, exercises and a 12-question quiz you must pass at 80%, followed by a pooled final exam and free and paid practice tests. Erudex is independent and not affiliated with Dental Assisting National Board.
