Passed the DANB Infection Control Exam last week with an 87%. I've been a dental assistant for 6 years so a lot of the material was familiar from daily practice, but the exam tests specific CDC guidelines and OSHA standards in a way that requires knowing the actual documents, not just general infection control habits. My first few practice sessions I was only hitting 71-73%, which was a wake-up call.
I studied for 7 weeks at about 45-60 minutes a day. Mosby's Dental Assisting Exam Review was my main resource for ICE-specific content. I focused heavily on the CDC Guidelines for Infection Control in Dental Health-Care Settings — the 2003 document still shows up in questions — and the OSHA Bloodborne Pathogens standard. Knowing specific exposure control plan requirements and what's required vs recommended was important.
The sterilization and disinfection classification questions (critical, semi-critical, non-critical items) showed up multiple times. So did hand hygiene protocols and the specific situations where each type of handwashing is required. Don't assume you know this from work — the exam uses precise CDC language that's sometimes different from how things get communicated in an actual office.
Time wasn't an issue — I finished 20 minutes early and reviewed everything. The questions are mostly scenario-based: given this situation, what's the correct procedure? Knowing the reason behind protocols helps you reason through unfamiliar scenarios.
7 weeks at under an hour a day sounds very manageable. Did you do anything specific for the OSHA recordkeeping sections? That's where I'm weakest right now and I'm not sure how much emphasis it gets on the actual exam.
The Spaulding classification system is absolutely on the test and people trip up on the edge cases. Dental handpieces and their classification is a classic question type. Make sure you know exactly where everything falls.
The 2003 CDC guidelines PDF is free online and worth reading at least the executive summary and key recommendations sections. Some questions feel like they came directly from that document. It's dry reading but worth it.
Passed ICE a year ago and the scenario format is what makes it harder than it looks on paper. You really have to apply the standard rather than recall it. Experience in a real dental office helps but you still need to know the specific regulatory language.
Congrats on the pass! I'm in a similar boat, been assisting for four years and studying around a packed schedule with two kids at home. What worked for me was breaking it into 20-minute chunks during lunch breaks and doing a ton of practice questions at night. Honestly the sharps and exposure control stuff tripped me up at first because I thought I knew it from daily work, but the exam is really specific about OSHA protocols. I found the danb danb sharps safety exposure control practice test super helpful for getting comfortable with exactly how they phrase those questions.
Don't underestimate the CDC guidelines section. It's not enough to know the general idea, you need to know the actual categories and terminology they use. I failed a few practice sections before it clicked. Give yourself at least three weeks even if the material feels familiar.
I actually failed the first time, which was humbling after six years in the field. My mistake was assuming clinical experience would carry me through without hitting the actual source material. It didn't. I knew infection control in practice but I couldn't answer questions about specific CDC categories or the exact OSHA bloodborne pathogens standard wording, and that's what got me.
Second time I printed out the CDC Guidelines for Infection Control in Dental Health-Care Settings and read it cover to cover, then did the same with the OSHA BBP standard summary. It's tedious but that's the gap. The exam really does test whether you know the documents, not just whether you're doing things right at work. Congrats on the 87%, that's a solid score and gives me hope for my retake next month.
I actually failed my first attempt by 3 points, so seeing your 87% honestly made me a little jealous lol. What I changed the second time was stopping trying to rely on what I "knew" from working and actually sitting down with the CDC guidelines and OSHA standards line by line. That was humbling. There's so much stuff I thought I knew but had just been doing by habit, and the exam does not care about habit.
The other thing that helped me a ton was drilling specific scenarios like waterline protocols, because those questions tripped me up both times until I actually practiced them. I found this set of questions on danb/questions/dental waterline safety 3 and it's way more specific than anything I'd studied before. It's not just memorizing steps, it's understanding why each step exists, and once that clicked I wasn't second-guessing myself on the tricky ones anymore.
This is huge, congrats! The wrong-answer thing is actually what clicked it for me too. I kept failing practice questions until I stopped asking "what's the right answer" and started asking "why would someone pick the wrong one." Like the waterline questions -- people mess those up because they confuse the rationale between HLD and sterilization, not because they don't know the vocab. I actually drilled a bunch of those through danb/questions/dental waterline safety 3 and it was brutal at first, but working through why each distractor was wrong taught me the CDC logic way better than any flashcard did.
For OSHA stuff specifically, I'd say don't just memorize the rule -- know what harm it's preventing. The exam loves to give you a scenario where two answers both sound compliant but one actually addresses the exposure risk correctly. If you can explain the "why" out loud for each answer choice, you're ready. It's slower study but it's the only thing that held up under actual test pressure.
