Case-Based Component (100 items)
(70%), Children (30 %). A minimum of 15 percent of Component B test questions will address
the medical management of compromised adults and children. A compromised patient is
defined as a person whose health status requires modification of standard treatment.
Each case presentation in the examination consists of:
1. synopsis of a patient's health and social histories,
2. patient dental charting,
3. diagnostic radiographs, and
4. clinical photographs of the patient (when necessary).
Each case contains from 10 to 15 questions about various aspects of this patient's dental care. These questions, totaling 100 for all of the cases, might derive from any of the basic sciences and clinical disciplines, including Patient Management. The proportion stemming from any particular discipline depends upon the nature of the case itself. For example, the case of an elderly adult might be based upon Maxillofacial Surgery / Pain Control Prosthodontics, and Operative Dentistry; whereas, a child's case might derive from Orthodontics, Pediatric Dentistry,and Patient Management.
In responding to case-based items, the candidate must:
1. Interpret the findings and information provided.
2. Identify the problems and make diagnoses.
3. Select materials, technique, and armamentarium.
4. Apply treatment.
5. Evaluate progress and complications.
6. Establish procedures for prevention and maintenance.
