"Take the exam" sounds simple. It isn't. Each of the five 2026 dental destinations runs a different exam architecture — single integrated cognitive test, paired written + clinical, sequential 4-exam pipeline, language-then-clinical hybrid. The architecture determines where time, money, and emotional bandwidth go.
INBDE — United States
- Format: single integrated cognitive exam. 500 questions over 1.5 days. Case-based.
- Pass rate: ~73% first attempt for foreign-trained.
- Fee: ~$520 per attempt via JCNDE.
- Replaces old NBDE Parts I and II.
- Required before IDP clinical year + state licensure exams.
- Prep: 6–12 months realistic.
ADC Written + Practical — Australia
- Two cognitive gates + one clinical gate.
- Written: 150 MCQ × 2 days (Dubai/Istanbul/UAE). ~AUD 2,500. Pass ~62%. 5-year validity from March 2026 (was 3).

ORE Part 1 + Part 2 — United Kingdom

NDEB four-exam pipeline — Canada
- Four sequential exams: AFK → ACJ → NDECC → Virtual OSCE.
- AFK: 150 MCQ, 5 hours, CAD 1,000. Pass ~65%.
- ACJ: clinical scenarios, 5 hours, CAD 1,000.

- Virtual OSCE: remote clinical, ~CAD 2,000.
- Total fees: ~CAD 14,000. Prep: 8–18 months.
- BTDPC alternative (ACFD pilot, 8 months) skips NDECC for Canadian PR holders.
Kenntnisprüfung — Germany
- Three sequential parts.
- Written: 4–5 hours, ~€400.
- Oral: 60-min panel exam with 3 examiners, ~€400, in German.
- Practical: 5 hours clinical procedures on manikin, ~€600.

| ADC (AU) | Written + Practical | ~62% / ~58% | AUD ~11,000 | Dubai/Istanbul + Melbourne |
| ORE (UK) | Part 1 + Part 2 | ~48% / ~52% | £7,500+ | Global + UK |
| NDEB (CA) | 4-exam pipeline | ~65% per exam | CAD ~14,000 | Canada (NDECC) + remote |

Pass rate is misleading
A 48% first-attempt pass rate (ORE Part 1) sounds dire compared to INBDE's 73%. But ORE candidates who fail typically retake within 6 months with high success. INBDE candidates who fail face IDP clinical-year setbacks that often add a full year. Pass rate × consequence-of-failure is the metric that matters, not first-attempt pass rate alone.
