What is the INBDE?

The Integrated National Board Dental Examination (INBDE) is a new written, cognitive examination for dental licensure scheduled to replace the previous National Board Dental Examination (NBDE) Part I and Part II examinations. The INBDE has the same overall purpose as the NBDE Part I and Part II: to assist state boards of dentistry in evaluating candidates for dental licensure. By integrating content covering the basic, behavioral, and clinical sciences, the INBDE is expected to be more relevant than the current NBDE Part I and Part II examinations.

The INBDE is open to both foreign and domestic dental graduates. It is common for US-based dental students to pursue the exam during their junior year of their postgraduate study, whereas international students are often required to pass in order to apply for state-side postgraduate courses or residency programs. Additionally, dental professionals who acquired their dental degree from an institution not accredited by the Commission on Dental Accreditation (CODA) will need their qualifications verified by the Educational Credential Evaluators

Test items on the INBDE will require candidates to draw from their knowledge of basic science, behavioral science, and clinical competencies to answer them correctly. For example, INBDE questions will ask about patient care, how dentists approach the practice of dentistry, and how dentists keep up with advances in the profession. The Joint Commission on National Dental Examinations (JCNDE) has issued a formal notification that the Integrated National Board Dental Examination (INBDE) has been available for administration since August 2020. The NBDE Part I was discontinued on July 2020, and the NBDE Part II was discontinued in August 2022.

Exam parameters are constantly being reviewed by the JCNDE. For updates, check out the ADA website Recent and Forthcoming Updates.

EXAM STRUCTURE

The INBDE is a 500-item examination (compared with a total of 900 questions on the NBDE Part I and Part II)  which will be administered via computer at test centers throughout the United States and US territories. It will take one and a half days to complete. Essentially, the content of the exam is the same, but the packaging is different.

  • All the topics and content of the NBDE Part 1 and 2, but restructured.
  • Computer based, 500 multiple choice questions over a day and a half vs 900 questions over two and half days.
  • A new user interface with an emphasis on case based questions.

Topics are compartmentalized based on the “Domains of Dentistry.” and integrates undergraduate content in order to achieve a more comprehensive evaluation of a candidate’s dental understanding. The exam extends over two days.

  • Day 1 –  3 sets of 100 questions and 1 set of 60 case-based questions (360)
  • Day 2 –  2 sets of 70 case-based questions (140)

The total exam time is 12.5 hours, which includes exam orientation and breaks.

NEW QUESTION STRUCTURE

The new INBDE is a restructured condensation of NBDE part I and II, reorganized into 3 main categories:

  • Practice and profession.
  • Diagnosis and treatment planning.
  • Oral Health Management.

The following drop down contains a comprehensive breakdown of the content of each section.

These percentages may be subject to change and should be verified with the most recent official documentation. The distribution of exam topics can be combined in the following table.

NEW EXAM LOOK

The INBDE is still a computer based multiple choice exam, now 500 questions over a day and a half. But the layout is slightly different, packed with more patient focused information. It will contain the following:

    • Description of the patients.
    • Description of the chief complaint.
    • Some background about the patient including dental and medical history, current medications etc.
    • Current findings which include any additional information regarding the pretreatment or diagnosis obtained.

Some questions in this examination involve a patient box. The patient box presents information available to the practitioner at the time of the visit. If no information is presented in a given area of the patient box, assume the information is either unknown or is not available. For example, if no allergies are listed, assume the patient has no known allergies at the time of visit. Always consider information presented in the patient box when answering questions and pay close attention to all provided patient information.

Some cases in this test involve dental charts. Below are samples of the types of dental charts used within the examination.

For further information about the INBDE exam format and developments, please review the JCNDE INBDE guide document.

NEW SCORING SYSTEM

The Joint Commission on National Dental Examinations (JCNDE) conducts criterion-referenced examinations, where the minimum passing score is established by subject matter experts through rigorous standard-setting activities. These standards are periodically reviewed to ensure they reflect current knowledge and skills necessary for safe practice. Examination results are reported as “pass” or “fail,” with detailed performance information provided to candidates who do not pass, including insights into specific clinical and foundational knowledge areas. The scoring system uses a scale from 49 to 99, with 75 as the minimum passing score, and adjustments are made to maintain this standard as necessary. Various examination forms are utilized to enhance security and ensure comparability of scores across different test versions. The scoring process incorporates psychometric analyses to accurately assess candidate skills, and some questions are experimental and not scored, contributing to future test development.
