How I Actually Used First Aid for the NBDE Part 1
The NBDE Part 1 was a dense exam covering basic sciences applied to dentistry. First Aid served as my primary review vehicle, but not in the way most people approach it. I treated it like a framework, not a textbook to read cover to cover. First Aid for the NBDE Part 1 is a condensed review book published by Kaplan. It covers microbiology, biochemistry, immunology, pharmacology, pathology, and oral biology. The NBDE Part 1 itself was retired and replaced by the INBDE, but people still reference this material when studying for the older exam or using it as a foundation for current dental board prep. The book is roughly 500 pages of bullet-pointed content. It assumes you already know the material from your coursework. It does not explain things from scratch. That distinction matters because people who pick it up expecting a textbook experience get frustrated fast.
My Actual Study Process
I started with pathology and microbiology because those sections carried the most weight on the exam. I went through each chapter once, slowly, marking anything I did not immediately understand. Then I went back a second time with UWorld question banks open. That combination — reading First Aid, then immediately testing myself — locked things in faster than any passive rereading ever could. For biochemistry and immunology, I spent maybe three days total across both subjects. These sections are narrow in scope but dense. I focused heavily on glycolysis, the Krebs cycle, and the major immune pathways. The NBDE asks fewer biochemistry questions than you might expect, but the ones it does ask are precise. I learned to recognize that pattern through practice questions rather than memorizing entire metabolic pathways verbatim.
The Edge Case That Caught Me Off Guard
There is a section in First Aid about dental radiography and radiation safety that feels minor but shows up more often than the book's treatment suggests. During my actual exam preparation, I noticed questions on this topic were scattered throughout multiple subject areas — not confined to one chapter. I had originally skimmed the radiation section entirely because it looked like straightforward memorization. That was a mistake. My workaround was simple: I printed out the relevant pages and taped them to my bathroom mirror. I read them while brushing my teeth every morning for two weeks. It seems ridiculous, but spaced repetition works whether the method is elegant or not. Those pages ended up being the difference between guessing and knowing on a few specific questions about ALARA principles and shielding requirements.

What the Book Gets Wrong
The pharmacology section is outdated in places. Drug classifications and some dosing information do not reflect the most current guidelines. I cross-referenced with Lippincott's Illustrated Reviews for Pharmacology whenever I encountered something that felt off. Spending thirty minutes verifying content in one section is better than spending three hours building knowledge on incorrect information. Another limitation: the question difficulty in First Aid's practice sections does not match the actual NBDE Part 1. The real exam includes more complex clinical vignettes. First Aid's practice questions are more direct and factual. Relying on them as a benchmark for exam readiness gives you a false sense of preparation. Use UWorld or NBDE-style question banks instead for that purpose.
Time Breakdown
I spent approximately six weeks studying for the NBDE Part 1 using First Aid as my core resource. Here is how that broke down: Pathology and microbiology took about three weeks. These were the heavy sections. I read First Aid thoroughly and completed all associated practice questions. Immunology and biochemistry combined took roughly five days. They are short sections but require active recall, not passive reading. Pharmacology took about four days for a first pass, with another two days dedicated to review and updating outdated information. The remaining week was mixed practice questions and reviewing flagged topics.
Common Pitfalls to Avoid
Most students read First Aid linearly from page one to page five hundred. This is inefficient. The book is designed to be used as a reference alongside question banks, not as a novel to be consumed in order. Start with the content area you find most difficult and build forward from there. Another mistake is underestimating the oral biology section. It is small in page count but disproportionately represented on the exam. Histology of dental tissues, tooth development, and embryology of the face and jaw appear frequently. I devoted one full day to this section alone, using both First Aid and online histology resources.
When First Aid Falls Flat
If you are struggling with foundational concepts in any of these subjects, First Aid will not help you. It is a review tool, not a learning tool. Students who have never encountered pharmacology or pathology before picking up this book will find it nearly useless. In those cases, pair it with a comprehensive textbook like Guyton and Hall for physiology or Robbins Pathology for pathological processes. First Aid fills gaps. It does not create understanding from nothing.
Bottom Line
First Aid for the NBDE Part 1 is a solid review resource when used correctly. It covers the right material, identifies high-yield topics, and provides a structured overview of what you need to know. It is not complete on its own. You will need question banks, supplementary textbooks for weak areas, and a disciplined schedule to make it work. The book gets you to the finish line. It does not run the race for you.
