candidate’s ability to:
A. Memorize dental terminology
B. Perform only written dental procedures
C. Demonstrate clinical skills and patient care competency
D. Complete administrative dental tasks
Answer: C. Demonstrate clinical skills and patient care competency
Rationale: The CDCA OSCE evaluates a dental candidate’s ability to
apply clinical knowledge, decision-making skills, infection control
principles, and patient-centered care. It is designed to assess practical
competency rather than simple memorization. The other options do not
represent the primary purpose of the examination.

C. National Board Dental Examination
D. Dental Assisting National Board
Answer: B. Commission on Dental Competency Assessments
Rationale: The CDCA OSCE is administered by the Commission on Dental
Competency Assessments, which develops clinical and written
assessments for dental professionals. The other organizations may be
involved in dental education or testing but do not administer the CDCA
OSCE.
3. A major focus of infection control during dental procedures is to:
A. Reduce appointment time
B. Prevent transmission of infectious diseases
C. Improve patient billing accuracy
D. Increase the number of procedures performed

,Rationale: Infection control practices are designed to protect patients,
dental professionals, and staff from exposure to pathogens. Proper
sterilization, personal protective equipment, and aseptic techniques are
essential components of safe dental practice.
4. Which personal protective equipment should be worn when
performing procedures involving possible exposure to blood or saliva?
A. Gloves only
B. Protective eyewear only
C. Gloves, mask, protective eyewear, and appropriate protective
clothing
D. No protection if the patient appears healthy
Answer: C. Gloves, mask, protective eyewear, and appropriate
protective clothing
Rationale: Standard precautions require appropriate PPE whenever
exposure to potentially infectious materials is possible. Wearing
complete protective equipment reduces the risk of occupational
exposure.

, A. Select instruments immediately
B. Review the patient’s medical history and treatment plan
C. Begin without speaking to the patient
D. Adjust the dental chair only
Answer: B. Review the patient’s medical history and treatment plan
Rationale: Reviewing medical history and the treatment plan helps
identify risks, contraindications, allergies, and necessary modifications
to care. Patient safety depends on proper assessment before treatment
begins.
6. The most effective method for preventing cross-contamination is:
A. Reusing disposable materials
B. Proper sterilization and infection control procedures
C. Cleaning instruments only with water
D. Avoiding documentation
Answer: B. Proper sterilization and infection control procedures
Rationale: Sterilization eliminates microorganisms from reusable
instruments and is a critical component of infection prevention. Water
cleaning alone does not reliably remove pathogens.
