Important notice and disclaimer concerning these practice items

The following items are offered to help candidates understand the types of questions that will be asked on the Integrated National Board Dental Examination (INBDE). It should be noted that practice test questions are not subjected to the same intense scrutiny, and do not undergo the same level of review, as items appearing on the actual examination. When developing examination content, the best questions are always reserved for placement on the actual examination (as opposed to placement on distributed lists of practice questions). The Joint Commission on National Dental Examinations (JCNDE) recommends that you use textbooks and lecture notes as primary sources for study. The current questions are provided to familiarize you with INBDE item formats. The box in the lower right corner of each question indicates the primary Foundation Knowledge (FK) area(s) and Clinical Content (CC) area(s) associated with that question (see final slides for a detailed list of FK’s and CC’s). The answer key appears as the last slide. These items may not be used for commercial purposes.

The JCNDE is an agency established by the American Dental Association (ADA). The JCNDE communicates and emphasizes the following cautions to candidates and others. All practice items are the copyrighted property of the ADA. These practice items are intended for the use of educators and students within the educational environment or for individual study and may not be reproduced in any format, whether paper or electronic, without expressed written permission of the JCNDE. The JCNDE will consider and may grant, on a case-by-case basis, specific requests by dental education programs for reproduction and use of these materials within the educational environment in either print or electronic format. Dental education programs interested in reproducing practice test questions should email [email protected]. The request should include an explanation of the intended use and an estimate of the number of copies that will be made.
