What is the AACD Certification Exam?

The American Academy of Cosmetic Dentistry (AACD) Certification Exam is the critical first step toward achieving the highly prestigious Accreditation in Cosmetic Dentistry. Administered by the American Board of Cosmetic Dentistry (ABCD), this rigorous written examination evaluates a dental professional's foundational knowledge, artistic judgment, and clinical expertise in aesthetic dentistry.

This exam matters because AACD Accreditation is widely recognized as the global gold standard in the cosmetic dental industry. Passing this test demonstrates a practitioner’s uncompromising dedication to advanced education, ethical standards, and superior patient outcomes, paving the way for the clinical case submission and oral examination phases.

Exam Format and Passing Score

The AACD written examination is meticulously designed to test real-world clinical applications and foundational science. It can be taken either as a computer-based test at Meazure Testing Centers or as a paper-based exam at the Annual AACD Scientific Session.

• Format: Multiple-choice questions.

• Number of Questions: 200 questions for dentists and 100 questions for laboratory technicians.

• Time Limit: Candidates are generally given up to 4 hours to complete the comprehensive 200-question dentist exam.

• Passing Score: The exam is graded on a pass/fail basis using a scaled scoring standard developed by the ABCD. Candidates should aim for a score of 70% or higher to comfortably pass the examination and advance in the credentialing process.

Core Exam Topics / Categories

The AACD exam comprehensively assesses the integration of scientific principles and aesthetic outcomes. Candidates are tested on a diverse range of clinical and theoretical scenarios across the following primary categories:

• Principles of Smile Design: Mastery of incisal edge position, tooth proportion, midline accuracy, axial inclination, buccal corridors, and ideal gingival architecture.

• Prosthodontics and Restorative Concepts: Best practices for tooth preparation and margin placement, pontic site development, implant prostheses, and evaluating tooth shade characteristics (e.g., translucency, value, and halo effect).

• Adhesion Protocols: Comprehensive understanding of advanced adhesive systems, cements, and surface treatment protocols for tooth structure, ceramics, and composites.

• Cosmetic Dental Materials: The scientific selection, handling, and application of modern materials, including lithium disilicate, zirconia, feldspathic ceramics, composite resins, and whitening systems.

• Occlusion and Function: The mechanics of stable function, including centric relation, maximum intercuspation, vertical dimension, and the anatomy and disorders of the temporomandibular joint (TMJ) and masticatory muscles.

• Interdisciplinary Care: Integrating comprehensive cosmetic treatment plans with orthodontics, periodontics, endodontics, and oral surgery.
