Master the ADAT
Your Path to Specialty Training
Compete for top residency spots with comprehensive ADAT prep. 15,000+ questions covering Biomedical Sciences, Clinical Sciences, and the Research section that trips up most candidates.
Who Takes the ADAT?
The ADAT opens doors to advanced dental education programs across North America.
Specialty Residency Applicants
U.S. dental school graduates pursuing specialty training in orthodontics, oral surgery, periodontics, endodontics, and more.
International Dentists (ITDs)
Internationally trained dentists applying to advanced standing programs in the U.S. or Canada to complete DDS/DMD degrees.
Canadian dental schools now use ADAT instead of AFK for ITD admissions

Experience ADAT-Style Questions
The ADAT tests biostatistics and clinical reasoning. Try these questions to see what you'll face.
A clinical study evaluated a fluorescence screening device for OSCC on 1,000 high-risk patients (smokers over 50). Results were compared to histopathological biopsy.
OSCC Screening Device vs. Histopathology
| Disease +Disease Present (OSCC+) | Disease -Disease Absent (OSCC-) | Total | |
|---|---|---|---|
| Test +Test Positive | 45TP | 190FP | 235 |
| Test -Test Negative | 5FN | 760TN | 765 |
| Total | 50 | 950 | 1000 |
A patient in this high-risk population screened positive using the new fluorescence device. What is the probability that this patient actually has Oral Squamous Cell Carcinoma (OSCC)?
Why the ADAT is High-Stakes
For Canadian programs, this isn't just a test—it's 70% of your application
The Problems
Learning in Isolation
When you don't understand a concept, there's no one to ask. Traditional prep is text-heavy, but clinical reasoning is visual—you need to see it to understand it.
The Stakes Are Massive
At McGill, your ADAT score is 70% of your preliminary assessment. At U of T IDAPP, it's mandatory. This isn't optional—it's your application.
Biostatistics Catches Everyone
40 questions on study design, sensitivity/specificity, p-values, confidence intervals. Most candidates haven't touched biostatistics since dental school—and it shows.
No "Passing" Score
The ADAT is competitive, not pass/fail. A 450 won't cut it for competitive programs. You need to be in the top percentiles—average isn't enough.

Don't Underestimate the Research Section
The Data, Research Interpretation & Evidence-Based Dentistry section is where many candidates lose points. It's only 40 questions, but they require a different skillset than clinical knowledge.
Sensitivity, specificity, odds ratios, confidence intervals
Study designs, bias identification, validity assessment
Applying research findings to clinical decisions
