Dental Hygiene (ADEX)

The ADEX Dental Hygiene Examination is based on specific performance criteria used to measure clinical competence. There are two skill-specific clinical and simulated clinical examinations:

–  The Patient Treatment Clinical Examination (PTCE) – evaluates candidates on their clinical and judgment skills. Clinical skills include detection and removal of calculus, accurate periodontal pocket depth measurements, tissue management, and final case presentation. Judgment skills include presenting an eligible patient, diagnostic-quality radiographs that meet all examination criteria, and an acceptable case selection of teeth that meets all calculus requirements.

–  The Computer Simulated Clinical Examination (CSCE) OSCE – is designed to assess various levels of diagnosis and treatment planning knowledge, skills, and abilities. Clinically-based questions are utilized through computer-enhanced photographs, radiographs, optical images of study and working models, laboratory data, and other clinical digitized reproductions.
