How to access your National Board results

Log in to your account to see your results

As a result of the cybersecurity incident that ADA recently experienced, we have experienced a temporary disruption to certain computer systems. We understand you may have questions about how this impacts your ability to access your National Board results.

If you know your DentPin and took your exam on or before April 23, 2022, you may log in to your account to see your results. You will also be able to see the state boards that you requested results be sent to. If you do not know your DentPin, unfortunately we don't have the capability to restore access at this time and will reach out as soon as we are able to. We appreciate your patience and understanding while we work to resolve the situation. We apologize for any inconvenience.

If you have additional questions about accessing your National Board results, please email
