The Question Will Change. The Concept Will Not.
Remembered questions can point you to what the exam cares about. They cannot hand you the exam. Here is how to use RQs the smart way: find the concept, master it properly, and give the most time to what matters most in the clinic.
We are not talking about leaked questions. Sharing live exam content breaks the exam rules and can cost you your score. This page is about concepts: the ideas the exam keeps testing, year after year, in new words.
Same Concept, Brand-New Question
Say a student remembers a question on local anesthesia. That exact question will almost certainly not come back. But the concept behind it, working out the safe maximum dose for the patient in front of you, will be tested again and again, each time with a different patient, a different drug and different numbers.
So if you know a concept is being tested, do not memorise the question. Master the concept until any version of it feels easy.
- 1Work out the milligrams in one cartridge. A 2% solution is 20 mg per mL, so a 1.8 mL cartridge holds 36 mg.
- 2Find the patient’s limit from their weight and the drug’s mg per kg maximum, never going over the absolute maximum.
- 3Subtract anything already given, then divide by the milligrams per cartridge.
A 70 kg adult needs two lower molars extracted. How many cartridges of 2% lidocaine with 1:100,000 epinephrine can you safely give?
A 20 kg child is booked for two pulpotomies. What is the most local anesthetic you can give at this visit?
Your patient already received three cartridges at another office this morning. How much more can you give today?
An RQ Is a Memory, Not a Question
What students post as “RQs” are questions rebuilt from memory, after a long and stressful exam. Details drop out. Words change. By the time a question has passed through a few group chats, what you are reading can be very far from what was actually asked, and the “answer” attached to it can be plain wrong. Watch how it happens:
A 58-year-old with controlled hypertension needs a lower molar extraction. Which anesthetic plan is most appropriate?
Something about anesthesia and a patient with high blood pressure.
RQ: epinephrine in hypertension??
Never give epinephrine to BP patients.
The real concept: a patient whose blood pressure is controlled can usually receive local anesthetic with epinephrine, as long as you aspirate, inject slowly and keep the epinephrine dose low. The memorised “never” rule is wrong, and it would lose you the mark.
RQs are still worth talking about. They tell you how difficult the exam felt and which areas came up often. Just do not treat them as a question bank.
The INBDE is not trying to catch you out. It is checking that you are a dentist the American dental system can trust with a patient.
That changes how you should study. The exam is built around what a safe dentist needs to know and do. Knowing what gets tested matters. Knowing how much each thing is worth matters just as much.
Weightage: What Would a Safe Dentist Need?
Here is the example Dr. T gives every batch. Tap the one you would rather master.
Red, orange and green complex bacteria
Which species sit in which complex, and in what order they colonise.
Clinical attachment loss, periodontal diagnosis, staging and grading
Measuring what is really there, naming the disease, and staging and grading it.
Before you spend an hour on a topic, ask: would this change what I do for the patient in the chair? If yes, master it. If no, understand it and move on.
How to Use RQs the Right Way
Name the concept
Ignore the remembered answer. Ask what idea the question was really testing.
Weigh it
Is it clinically important? If it changes diagnosis or treatment, it goes to the top of your list.
Master it properly
Learn it from a trusted source until you can answer any version of it, not just the one you saw.
Test it in new cases
Practise with fresh patient scenarios. If a new version trips you up, you have found your gap.
RQs: Common Questions
No, and we will never use or share leaked exam content. By RQs, students mean questions they try to remember after sitting the exam. They can show you which concepts and topics the exam likes. They cannot show you the exact question you will get.
Enough to see which concepts keep coming back, and no more. The moment an RQ points you to a concept, stop collecting and go master that concept properly from a reliable source.
Treat them with suspicion. They are recalled from memory under stress and passed along in group chats, so details get lost and wrong answers spread fast. Check every one against your textbook or course material.
Yes. They are a fair way to discuss how hard the exam felt and which areas came up often. Use them to set priorities, not as a question bank to memorise.
Ask whether the concept would change what you do for the patient in the chair. Diagnosis, treatment planning, drug doses and medical emergencies all do, so they are worth mastering first.
Our Master Files are arranged by how often topics are tested, so the most important concepts come first. When you get stuck, the Queries & Help Section puts your question in front of our faculty, who answer you personally.
