CDT Questions and Answers

What is the Certified Dental Technician (CDT) exam?

The CDT exam is a professional certification administered by the National Board for Certification in Dental Laboratory Technology (NBC). It validates the knowledge and skills of dental laboratory technicians in areas such as crown and bridge, complete dentures, partial dentures, ceramics, orthodontics, and implants. Earning the CDT credential demonstrates competency recognized across the U.S. dental laboratory industry.

What is the format of the CDT certification exam?

The CDT certification process includes three separate exams: a Written Comprehensive Exam covering general dental laboratory knowledge, a Written Specialty Exam in your chosen discipline, and a hands-on Practical Exam. The written portions are multiple-choice and computer-based, while the practical tests your ability to complete real laboratory tasks within a timed setting.

What is the passing score for the CDT exam?

Candidates must achieve a scaled score of at least 75 on each of the three CDT exam components to pass. Each section is scored independently, so you must pass the Written Comprehensive, Written Specialty, and Practical exams separately. If you fail one section, you only need to retake that specific portion rather than the entire exam.

What topics are covered on the CDT Written Comprehensive Exam?

The Written Comprehensive Exam covers dental anatomy, dental terminology, infection control, occlusion, materials science, safety regulations, and basic laboratory procedures. It also tests knowledge of OSHA standards, equipment operation, and ethics. This section is required for all candidates regardless of which of the six specialty areas they choose to pursue.

Who is eligible to take the CDT exam?

Eligibility requires a combination of education and hands-on experience in dental laboratory technology. Candidates typically need either graduation from an accredited dental technology program plus two years of experience, or five years of full-time laboratory work experience. Graduates of non-accredited programs and self-taught technicians may also qualify through the experience pathway.

How do I register for the CDT exam?

Registration is completed through the National Board for Certification in Dental Laboratory Technology website at nbccert.org. Candidates submit an application, documentation of eligibility, and exam fees. Once approved, the NBC provides authorization to schedule the written exams at Prometric testing centers and to arrange the practical exam at an approved site.

What are the six CDT specialty areas?

The CDT credential offers six specialty disciplines: Complete Dentures, Partial Dentures, Crown and Bridge, Ceramics, Orthodontics, and Implants. Candidates choose one specialty for their Written Specialty Exam and Practical Exam. Technicians may pursue additional specialties later by passing the corresponding specialty written and practical exams without retaking the Comprehensive Exam.

What are the best preparation tips for the CDT exam?

Review the NBC Candidate Handbook and official content outlines to focus your study on tested topics. Use recommended textbooks on dental materials, anatomy, and laboratory procedures, and take timed practice tests to build speed and accuracy. For the practical exam, rehearse the specific procedures in your specialty under realistic time constraints using proper materials and equipment.
