B. Treatment evaluation
C. Dental hygiene diagnosis
D. Periodontal instrumentation
Answer: A
6. A dental hygienist reviews a patient's assessment findings and determines

A. Assessment
B. Planning
C. Diagnosis
D. Evaluation
Answer: B
8. A patient returns several weeks after receiving individualized oral hygiene

C. Implementation
D. Evaluation
Answer: D
9. A dental hygiene student is asked to explain evidence-based practice. Which
description most accurately represents evidence-based dental hygiene

and preferences

Answer: C
pg. 3
, 10. A hygienist wants to determine whether a specific preventive intervention is
supported by scientific literature before incorporating it into patient care.
Which approach best demonstrates evidence-based decision-making?
A. Reviewing relevant scientific evidence and integrating it with clinical
judgment and patient preferences
B. Selecting the intervention because it is popular among classmates
C. Choosing the procedure with the highest financial reimbursement
D. Using the procedure only because it has been performed for many years
Answer: A
11. When developing a searchable clinical question using the PICO framework,

the intervention, comparison, and outcome. What does the letter P
represent?
A. Prevention
B. Patient, population, or problem
C. Professional judgment
D. Periodontal classification
Answer: B
12. A researcher compares a new oral hygiene intervention with the

whether the new method produces better outcomes. Which component of
PICO does the conventional intervention represent?
A. Outcome
B. Patient
C. Intervention
D. Comparison
Answer: D
13. A dental hygiene researcher measures the reduction in gingival
inflammation after a patient education program and records numerical
scores before and after the intervention. Which research approach is most
consistent with these numerical measurements?
pg. 4
