Domain 1: Exam Structure & ADEX Eligibility (Q1–Q20)
• Q1: Explain 'ADEX Status' and the three required eligibility qualifications for a
candidate.
o Answer:
▪ Eligibility: You must (1) Be a graduate or student in the final year of a
CODA-accredited dental/dental hygiene program, (2) Have a passing score
on the Integrated National Board Dental Examination (INBDE) or NBDHE,
and (3) Be in good academic standing.
▪ ADEX Status: This refers to a candidate's specific rights and standing
within the ADEX testing system. According to the manual, the three
required qualifications for "ADEX Status" are eligibility for a clinical exam,
possession of a valid CDCA-WREB-CITA account, and completion of a
Candidate Attestation.
• Q2: What is the structure of the ADEX Dental Examination starting August 1, 2026?
, o Answer: The examination will consist of three distinct parts:
1. DLOSCE (Dental Licensure Objective Structured Clinical
Examination): The image and 3D-model-based computer simulation
assessing clinical judgment and treatment planning.
2. Manikin-based Clinical Skills (Restorative & Prosthodontic
sections): Testing traditional hand skills.
3. Periodontal and Implant sections: Root planing, scaling, or implant-
specific procedures.
• Q3: How is the OSCE/CSCE defined in the context of the ADEX exam?
o Answer: The OSCE (Objective Structured Clinical Examination) or CSCE
(Computer-simulated Clinical Examination) involves presenting clinical situations
or scenarios that require decisions regarding diagnosis, treatment planning, or
patient management. It is a timed, computer-based simulation.
• Q4: What are the passing score requirements for the ADEX exam?
o Answer:
▪ DLOSCE & Restorative Clinical Sections: Pass/Fail grading using critical
criteria (must pass all critical criteria) and non-critical criteria (awarded
points).
▪ Overall Success: You must pass every individual section of the exam
(DLOSCE, Prosthodontics, Periodontics, Implants, etc.) to obtain a passing
result for the entire ADEX license.
▪ *Note: The reported first-time pass rate for 2026 for certain sections (like
OSCE Endodontics) is around 79% for some cohorts, so preparation is
key.*
• Q5: Which states/jurisdictions accept the ADEX exam for dental licensure?
o Answer: ADEX is accepted or required by law in 51 U.S. jurisdictions, including
Washington, D.C., Puerto Rico, and the U.S. Virgin Islands.
• Q6: Can I retake the DLOSCE if I fail it on my first attempt?
o Answer: Yes, but with caveats. After August 1, 2026, you cannot take the DLOSCE
as a standalone exam. If you fail the integrated ADEX exam, you must retake
