INBDE® prep — for every candidate

INBDE prep that does not assume you just left a U.S. dental school.

Candidates from non-CODA-accredited programs accounted for 39.3% of INBDE candidate administrations in 2025. Many are internationally trained dentists studying on a longer runway. Dentovio starts from that side: Patient Box case practice, Foundation Knowledge modules that re-teach instead of remind, and study schedules sized for a real 3–6 month runway.

The exam at a glance

  • The single written board for U.S. dentist licensure, accepted in all 50 states.
  • Day 1: 300 standalone questions plus 60 case-based items.
  • Day 2: 140 case-based items in Patient Box testlets — chart, meds, radiographs, and distractor data.
  • The 2026 fee is $890, plus a $435 non-CODA processing fee — about $1,325 per attempt for most international candidates.

Built for the non-CODA pathway

Most INBDE prep treats internationally trained dentists as an afterthought: same 45-day plans, same assumptions about recent U.S. coursework. Dentovio's modules re-teach Foundation Knowledge under U.S. clinical framing instead of assuming you saw it last semester.

Case-first, because Day 2 is

Two hundred of the exam's 500 items are case-based, and Day 2 is nothing but Patient Box testlets. Practicing standalone flashcards does not build the chart-reading endurance the second day demands — so case practice is the core here, not an add-on.

Access until you pass

One payment, no subscription clock. Your account keeps full INBDE access — including every new module as it clears review — until you pass the exam.

What's inside

Everything is organized around how internationally trained dentists actually pass.

The INBDE blueprint crosses 56 Clinical Content areas with 10 Foundation Knowledge areas. Dentovio's prep follows that structure — but paces it for candidates who are working, years past their foundational coursework, or studying in a second language.

Foundation Knowledge modules that re-teach, not just remind
Six-section practice simulation for case endurance
ESL-aware explanations in plain English, with clinical terms glossed
Realistic 3-month and 6-month study schedules
Original items written from source-cited clinical references
