I'm a general dentist considering taking the ADAT next cycle and trying to be realistic about how much prep time I actually need. I graduated 3 years ago and have been in private practice since then. My plan is to study for 10 weeks at about 1.5 hours on weekdays and 3 hours on Saturdays, which works out to roughly 125 hours total. Some people on here say 8 weeks is enough and others took 16 — I can't tell what's realistic.
My main concern is that I've been out of dental school long enough that some didactic material is rusty. Oral medicine and pathology feel the shakiest because I deal with maybe 5% of those cases in general practice. Dental materials science is another weak area — I know the clinical applications but composition and properties questions trip me up. The diagnosis and treatment planning sections feel more natural since that's basically what I do every day.
I've heard the ADAT is weighted more heavily toward advanced clinical scenarios than the NBDE was, which makes sense given its purpose. If anyone who's taken it recently can weigh in on what actually shows up versus what the prep books focus on, that would be really helpful. Also curious how people handle the time pressure — are most people finishing with time to spare or is it tight?
Timing is tight but manageable. I finished with about 8 minutes left on my first pass and used that to revisit flagged questions. The questions are longer than NBDE questions though so don't underestimate the reading load — read carefully and don't rush through scenarios.
Took it 8 months ago and 10 weeks was comfortable for me at 3 years out. The oral medicine and pathology sections are heavy — probably 20-25% of what I saw. Neville's oral pathology textbook is overkill but the summary tables in the back were genuinely useful for review.
The dental materials questions were harder than I expected — not just composition but failure modes and clinical indications for one material over another. Worth reviewing your dental school notes rather than relying only on ADAT prep books for that section.
I'm 5 years out from dental school and passed on my first attempt with 11 weeks of prep at similar hours. Your clinical experience genuinely helps with treatment planning — that section felt straightforward compared to the basic science content. The key is doing as many practice questions as possible in the last 3 weeks.
