INBDE Pro Lab is built for any candidate preparing for the Integrated National Board Dental Examination (INBDE) — whether you are a D3 or D4 student at a US dental school, a recent US dental graduate, or an international dentist seeking relicensation. The question bank, AI tools, Prometric simulation, and performance analytics deliver value to every INBDE candidate regardless of background.

The Integrated National Board Dental Examination (INBDE) is the national licensing exam administered by the Joint Commission on National Dental Examinations (JCNDE). It replaced NBDE Parts I and II in 2020 and has been fully in effect since 2022. It consists of 500 questions administered over two days at Prometric Testing Centers. A passing score is required for licensure to practice dentistry in the United States. In 2024, the JCNDE increased the passing performance standard, making the exam significantly more challenging.

We recommend starting at least 2–3 months before your scheduled exam date to benefit fully from the Performance Heatmaps, Readiness Score, and spaced repetition. However, even 4–6 weeks of focused daily practice with 7,000+ questions and AI Deep Dive makes a meaningful difference. The earlier you start, the more data Pro Lab collects about your weak areas — and the more targeted your study sessions become. There is no downside to starting early.

The most important difference is one most people overlook: INBDE Pro Lab is the only platform built exclusively around questions. No video lectures. No PDFs. No slideshows. Just 7,000+ high-yield questions — because answering questions is the only thing that actually prepares you for a test. Beyond that: (1) AI Deep Dive powered by Google Gemini gives you a real-time clinical breakdown on every single question. (2) Pixel-perfect Prometric simulation — the only platform that replicates the exact interface you will see on exam day. (3) Performance Heatmaps and Readiness Score that update after every question, so you always know exactly where to focus.

Pro Lab covers all INBDE content areas as defined by the JCNDE blueprint, including: Anatomy, Biochemistry, Physiology, Microbiology, Pathology, Pharmacology, Periodontics, Prosthodontics, Operative Dentistry, Oral Surgery, Orthodontics, Pediatric Dentistry, Endodontics, Radiology, Biomedical Sciences, and Patient Management. Every question is tagged by subject, difficulty, and INBDE domain so you can filter and focus on exactly what you need.

AI Deep Dive is powered by Google Gemini and available on every question in Pro Lab. After answering any question — regardless of whether you got it right or wrong — tap the sparkle icon (✦) to receive a real-time clinical breakdown: why the correct answer is correct, why each wrong answer is wrong, and the underlying pharmacological, pathological, or clinical science that connects them. It functions like a specialist tutor available 24 hours a day, 7 days a week, for all 7,000+ questions in the platform.

The INBDE is administered at Prometric Testing Centers on a specific proprietary interface with a specific layout, timer format, navigation system, and question display. The majority of candidates have never interacted with this interface prior to exam day — which adds unnecessary cognitive load and anxiety during an already high-stakes test. Pro Lab's Simulation Mode replicates this interface pixel-by-pixel, including the exact timer display, flagging system, and question navigation. By exam day, you will have practiced in this environment dozens of times. No surprises, no wasted mental energy.

Subject Mastery Heatmaps are real-time visual breakdowns of your performance across every INBDE content area. Subjects where you score consistently high appear green. Areas with low performance appear red. Subjects in between appear yellow. This visualization — updated after every session — tells you exactly where to focus your limited study time, eliminating the common mistake of reviewing material you already know while neglecting critical weak spots. Combined with your Exam Readiness Score, heatmaps give you a data-driven study plan you can act on immediately.

Your Exam Readiness Score is a live, composite score that updates after every study session based on your performance across all subjects, difficulty levels, and question types. It gives you an objective signal of how prepared you are before you sit the real exam. Students consistently report that their Readiness Score closely predicted their actual exam result. We recommend scheduling your exam once your score reaches a sustained level you are confident in — not before.

Daily Run is a personalized daily question set generated automatically based on your weakest subjects, your recent performance trends, and the INBDE content weighting. Instead of deciding what to study each day — a decision that most students make poorly — Pro Lab makes that decision for you using your own performance data. Each Daily Run is typically 20–40 questions targeting the areas most likely to move your Readiness Score upward.

Pro Lab contains 7,000+ high-yield INBDE practice questions. Every question is peer-reviewed, subject-tagged, difficulty-rated, and updated to reflect the current JCNDE exam blueprint and 2024 performance standard. The question bank is continuously updated — new questions are added regularly and outdated content is retired. Your subscription always gives you access to the full, most current bank.

Pro Lab offers three subscription plans: 1 Month — $99, 3 Months — $249 ($83/month), and 6 Months — $349 ($58/month). Every plan includes full access to all 7,000+ questions, AI Deep Dive, Prometric Simulation, Performance Heatmaps, Readiness Score, and the full mobile app. There are no feature restrictions across plans — only the duration differs. All plans include a 7-day free trial (no credit card required). The 1-month plan renews automatically each month. The 3-month and 6-month plans are one-time purchases that do not auto-renew.

Yes — every plan includes a 7-day free trial with full access to every feature. No credit card is required to start. During your trial you have unrestricted access to all 7,000+ questions, AI Deep Dive, Simulation Mode, Performance Heatmaps, Readiness Score, and the mobile app. After 7 days, you can choose a paid plan to continue. If you do not subscribe, your access ends automatically with no charges. Your progress and data are saved for 30 days in case you return.

Your access to Pro Lab ends on the expiry date of your subscription period. You will not be charged automatically — Pro Lab subscriptions are not auto-renewing. To continue, you must manually purchase a new plan at inbdeprolab.com. Your performance history, progress data, and heatmaps are saved for 60 days after expiry, so if you renew within that window you pick up exactly where you left off.

Pro Lab accepts all major credit cards (Visa, Mastercard, American Express, Discover) and debit cards. Payments are processed securely. We do not store payment card information on our servers. All transactions are encrypted and handled through a PCI-compliant payment processor.

We built Pro Lab with the philosophy that the best INBDE preparation should be accessible to every dental student — not only those who can afford a premium price. We invest in building better technology and a larger, higher-quality question bank rather than in heavy marketing budgets. The result: more features, more questions, and a lower price. We believe students who compare the options choose Pro Lab on merit.

Pro Lab works on all modern devices: desktop computers, laptops, tablets, and smartphones. The web platform supports Chrome, Firefox, Safari, and Edge (latest two versions). The mobile app is available on iOS (iPhone and iPad, iOS 14+) and Android (Android 9+). Every feature — including AI Deep Dive, Simulation Mode, Performance Heatmaps, and Daily Run — is available on mobile. Progress syncs automatically across all your devices in real time.

Yes. The JCNDE introduced a revised, more demanding performance standard in 2024, and our question bank is continuously reviewed and updated to match the current blueprint and difficulty distribution. New questions are added regularly by our team of dental specialists, and retired content is removed. Every question is tagged with its INBDE domain, subject area, and difficulty level so your practice sessions accurately reflect what you will encounter on exam day.

Yes. All your progress, performance history, heatmaps, and session data are stored securely in the cloud and sync across every device linked to your account. If your subscription lapses, your data is retained for 60 days. If you renew within that window, everything is intact. We strongly recommend using the same login email across devices to ensure consistent sync.

The web platform requires an internet connection. The mobile app caches a limited set of questions for offline practice — you can continue answering questions without connectivity, and your results sync automatically when you reconnect. AI Deep Dive and real-time performance updates require an active connection. We recommend downloading offline question sets on the mobile app before traveling or studying in low-connectivity areas.

⚠ All sales are final. INBDE Pro Lab does not offer refunds.

Given the nature of digital subscription products with immediate access to all content, all purchases are non-refundable once access has been granted. This applies to all plan types (1-month, 3-month, and 6-month). If you have a technical issue preventing access, please contact our support team within 48 hours and we will work to resolve it. We strongly encourage every prospective subscriber to take full advantage of the 7-day free trial before purchasing a paid plan — the trial exists precisely so you can evaluate the platform at zero cost and zero risk before committing.

⚠ INBDE Pro Lab does not offer a pass guarantee of any kind.

We do not guarantee or warrant that use of Pro Lab will result in a passing score on the INBDE. Exam outcomes depend on many individual factors beyond any study tool — including prior academic preparation, study consistency, test-taking conditions, and personal performance on exam day. Our ~100% pass rate reflects the real-world outcomes of our committed student community, not a contractual promise. We provide the most comprehensive, highest-quality preparation platform available. The rest is up to you.

Pro Lab subscriptions are not automatically recurring. Each plan (1-month, 3-month, or 6-month) is a one-time purchase for a defined access period. There is nothing to cancel — your subscription simply expires at the end of the period. You will not be charged again unless you manually purchase a new plan. If you wish to stop using Pro Lab, you do not need to take any action.

No. Each Pro Lab subscription is licensed for a single user only. Account sharing is not permitted and will result in account suspension without refund. Your login credentials are personal — sharing them compromises the accuracy of your own performance data, as heatmaps and readiness scores are based on your individual session history. Each user must purchase their own subscription.

We take data privacy seriously. We collect only the data necessary to provide the service: your email address, account credentials, and in-platform performance data (questions answered, scores, session history). We do not sell, rent, or share your personal data with third parties for marketing purposes. Performance data is used solely to power your heatmaps, readiness score, and AI personalization features. All data is transmitted and stored with encryption. You may request deletion of your account and associated data at any time by contacting support. Our full privacy policy is available at inbdeprolab.com/privacy.

AI Deep Dive is powered by Google Gemini and produces high-quality, clinically informed explanations reviewed in context by our team. However, AI-generated content may contain errors, outdated information, or overgeneralizations. All AI explanations should be treated as educational study aids, not as definitive clinical guidance. When in doubt, cross-reference with authoritative dental textbooks or your program's instructional materials. INBDE Pro Lab is a test preparation tool and is not a substitute for formal dental education or clinical training.

If a technical issue interrupts a timed Simulation Mode session — such as a connectivity drop, browser crash, or app error — the session will be paused and your progress up to that point is saved. You may resume from where you left off. If the session data is lost due to a platform error on our side, contact support within 24 hours and we will restore or credit the session. We are not responsible for interruptions caused by user-side connectivity issues or device failures.

Yes. All payment transactions are processed through a PCI-DSS-compliant payment gateway using industry-standard TLS encryption. INBDE Pro Lab does not store your credit card number, CVV, or full payment details on our servers. Payment data is tokenized and handled entirely by our payment processor. You will receive an email confirmation for every transaction. If you notice an unauthorized charge, contact us and your card issuer immediately.
