CHICAGO: In a landmark move poised to reshape dental licensure across the United States, the American Dental Association (ADA) and the American Board of Dental Examiners (ADEX) have finalized a major agreement to modernize how future dentists are evaluated for clinical competence and readiness to practice.
Under the agreement, ADEX will formally incorporate the ADA’s Dental Licensure Objective Structured Clinical Examination (DLOSCE) into the ADEX Dental Examination no later than August 1, 2026 — a development being viewed as one of the most significant reforms in U.S. dental licensure assessment in recent years.
The agreement is expected to strengthen patient safety standards, improve licensure portability for dentists, streamline examination pathways, and modernize competency-based dental assessments using advanced simulation and evidence-based testing methods.
A major shift in U.S. dental licensure
The integration of the DLOSCE into the ADEX Dental Examination marks a substantial evolution in how clinical competency is measured for dental graduates entering professional practice.
Unlike traditional examination models that rely heavily on procedural testing, the DLOSCE incorporates advanced image-based assessments, clinical scenarios, diagnostic interpretation, and 3D modeling technologies designed to mirror real-world patient care environments.
According to the ADA and ADEX, the updated examination model will continue evaluating candidates’ clinical hand skills while significantly expanding the assessment of treatment planning, decision-making, diagnosis, and patient-centered clinical judgment.

Dental education leaders say the shift reflects broader transformations taking place within healthcare education, where competency-based and technology-driven assessments are increasingly replacing older examination formats.
Why the agreement matters
The agreement carries major implications for dental graduates, licensing boards, dental schools, and healthcare systems across the United States and affiliated jurisdictions.
The ADEX Dental Examination is currently accepted or required in 48 U.S. states and several additional jurisdictions, including Washington, D.C., Puerto Rico, Jamaica, and the U.S. Virgin Islands.
By aligning licensure assessment pathways under a modernized framework, the agreement is expected to enhance licensure portability and workforce mobility for dentists seeking to practice across multiple states.
“This agreement represents an important milestone for the dental profession. By aligning pathways to licensure and advancing candidate assessment, we are strengthening licensure portability, supporting a more mobile and responsive workforce, and ensuring that patient safety remains paramount.” ADA President Dr. Richard Rosato said in an official statement.
Focus on patient safety and evidence-based assessment
Both organizations emphasized that patient protection remains central to the modernization effort.
The updated examination structure aims to ensure dentists demonstrate not only technical procedural skills but also critical clinical judgment, ethical reasoning, diagnosis capabilities, and treatment-planning competence before entering professional practice.
ADEX Chair Dr. Mark Armstrong stated that the agreement strengthens alignment across licensure assessment components while preserving the hand-skills evaluation still required in most U.S. jurisdictions.
“ADEX has long served state dental boards to support licensure processes that reflect both public protection and clinical competence,” Armstrong said.
The organizations noted that the DLOSCE’s use of highly detailed clinical simulations and 3D scenarios allows candidates to engage with examination content that closely resembles real-world dentistry.
Extensive collaboration behind the reform
According to the ADA and ADEX, the agreement follows months of collaboration among major dental education and examination bodies beginning in 2025.
The initiative involved coordination between:
- American Dental Association (ADA)
- American Board of Dental Examiners (ADEX)
- Joint Commission on National Dental Examinations (JCNDE)
- ADA Council on Dental Education and Licensure (CDEL)
In March 2026, both the ADA Board of Trustees and the ADEX Board of Directors approved the general framework that ultimately led to the finalized agreement.
Stakeholders involved in the discussions stressed the importance of ensuring dental licensure systems evolve alongside advances in clinical education, healthcare technology, simulation training, and patient care standards.
Key timeline and implementation changes
As part of the transition:
- ADEX will officially sunset its DSE OSCE no later than August 1, 2026.
- All ADEX Dental Examination administrations after that date will include the DLOSCE component.
- The DLOSCE will no longer be offered as a standalone exam for new candidates after August 1, 2026.
- All standalone DLOSCE administrations will completely cease after October 9, 2026.
The transition effectively consolidates licensure assessment pathways into a unified and more modern examination framework.
Broader implications for the future of dentistry
Dental policy experts say the agreement reflects a broader global movement toward competency-based healthcare licensing and assessment systems.
Medical and dental regulators worldwide are increasingly emphasizing patient-centered evaluation methods, standardized competency measures, clinical reasoning assessments, and digital simulation tools.
The ADA-ADEX agreement is expected to influence future conversations around licensure modernization, healthcare workforce mobility, and examination reform both within the United States and internationally.
For dental students and educators, the transition also signals a growing emphasis on integrated clinical reasoning, evidence-based decision-making, and practical patient management skills alongside traditional procedural competence.
As dentistry continues evolving with new technologies and treatment approaches, leaders say modernized licensure systems will play a critical role in ensuring public trust, clinical excellence, and patient safety.
