Frequently Asked Questions
What is the INBDE pass rate?
The INBDE has a 99%+ first-attempt pass rate for students from CODA-accredited dental programs (only 0.8-1.3% fail rate). However, international dental graduates face a more challenging 65-75% pass rate. The exam uses a scaled score of 49-99, with 75 as the minimum passing score. With comprehensive preparation, you can join the vast majority who pass on their first attempt.
How is the INBDE different from the old NBDE?
The INBDE replaced NBDE Parts I and II with a single integrated exam. Unlike the separate basic science (Part I) and clinical science (Part II) format, the INBDE integrates biomedical and clinical knowledge in every question. It uses more case-based and patient-centered questions, emphasizing clinical application rather than rote memorization of isolated facts.
How many questions are on the INBDE?
The INBDE has 500 multiple-choice questions administered over 2 days. Not all questions are scored — some are experimental pretest questions used to evaluate items for future exams. The exam includes both standalone questions and case-based question sets with dental charts and patient information. Total testing time is 12 hours and 30 minutes including breaks.
What topics are tested on the INBDE?
The INBDE covers 56 Clinical Content areas grouped into Diagnosis & Treatment Planning (30%), Oral Health Management (40%), and Practice & Profession (10%), plus 10 Foundation Knowledge areas in Biomedical Sciences (10%) and Dental Sciences (10%). The highest-yield topics include restorative, endodontics, periodontics, pharmacology, and oral pathology.
How long should I study for the INBDE?
Plan for 300-500 hours of study over 3-6 months while in dental school. Most students begin focused preparation 3-4 months before the exam. Allocate 40% of study time to clinical sciences, 30% to diagnosis/treatment planning, 20% to biomedical foundations, and 10% to practice/profession topics. Complete at least 3,000 practice questions.
Can international dental graduates take the INBDE?
Yes, international dental graduates can take the INBDE. They must have their educational credentials evaluated by ECE (Educational Credential Evaluators), pay an additional $435 processing fee (total $1,325), and obtain a Certification of Eligibility Form. Many international graduates also enroll in Advanced Standing Programs at CODA-accredited schools to strengthen their preparation.
What is the career outlook for dentists?
The BLS projects 4% employment growth for dentists from 2023-2033, with approximately 5,100 job openings per year. The median annual salary for general dentists is $170,910 (BLS 2024), with specialists earning significantly more. There are approximately 162,000 dentist jobs in the U.S., and demand continues to grow as the population ages.
