Comparison

ADC vs NBDE/INBDE — Australia vs USA: Which Pathway Should You Choose?

Australia lets you prove competence through exams and register directly. The US requires you to repeat 2 years of dental school before you can practise. Here is the full comparison — costs, timeline, difficulty, salary, and immigration — so you can make an informed choice.

ADC (Australia) overview

The ADC exam is the pathway for overseas-trained dentists to practise in Australia. Three stages: initial assessment, written exam (280 SBQs, 2 days), and practical exam (OSCE + manikin, Melbourne). Total cost: AUD $16,000-$24,000. No limit on attempts. Dentistry is on Australia's skilled migration list.

NBDE/INBDE (USA) overview

In the United States, overseas dentists cannot simply pass a licensing exam and practise. You must complete an Advanced Standing Program (typically 2 years) at an accredited US dental school, then pass the INBDE (Integrated National Board Dental Examination) and a regional clinical board exam. The NBDE Part I and II have been replaced by the INBDE since 2020.

The fundamental difference

The ADC is an exam-based pathway — you prove your competence through examinations and register directly. The US pathway requires you to repeat 2 years of dental school at a US institution before you can practise. This means the US pathway costs 5-10x more and takes significantly longer.

For most overseas dentists, the ADC pathway is dramatically more accessible and affordable. The US pathway makes sense only if you specifically want to practise in the United States and are willing to invest USD $100,000-$200,000+ in tuition and living expenses for an Advanced Standing Program.

Which should you choose?

Choose ADC (Australia) if: You want to practise sooner, at lower cost, with a clearer PR pathway and no requirement to repeat dental school.

Choose USA if: You specifically want to practise in the US, are prepared for 2+ years of additional education and USD $100K+ investment, and want access to the US dental market specifically.

Frequently asked questions

Can I practise in the USA with an ADC pass?
No. The ADC is only valid for Australian registration. To practise in the US, you need to complete an Advanced Standing Program and pass the INBDE and a regional clinical board exam.
Is ADC easier than INBDE?
They test different things. The ADC tests Australian clinical standards through SBQ vignettes. The INBDE tests US dental knowledge through integrated MCQs. Neither is inherently easier, but the ADC pathway is significantly cheaper and faster.
Can I do ADC and INBDE?
Technically yes, but the clinical frameworks are different and the US pathway requires 2 years of additional education. Most candidates choose one pathway based on where they want to live and practise.
