Introduction
The Florida Dental Hygienist Licensure Examination evaluates the knowledge,
judgment, and clinical decision-making required for safe, ethical, and evidence-based
dental hygiene practice. Candidates are expected to integrate biomedical sciences,
patient assessment, periodontal therapy, infection control, radiology, pharmacology,
ethics, and Florida-specific professional responsibilities into realistic clinical scenarios.
This practice examination reflects current professional standards and emphasizes
critical thinking rather than simple memorization. Questions require careful
interpretation of patient histories, risk factors, treatment planning, emergency
management, and regulatory compliance. Mastery of these topics prepares
candidates for successful licensure and competent independent performance within
the legal scope of dental hygiene practice in Florida.
Question 1
,A patient with a prosthetic heart valve presents for periodontal debridement
involving manipulation of gingival tissue. Which action is most appropriate before
treatment?
A. Proceed without antibiotic prophylaxis because scaling is minimally invasive.
B. Verify whether antibiotic prophylaxis is indicated according to current
recommendations and consult the patient's physician if necessary.
C. Delay treatment for six months.
D. Prescribe prophylactic antibiotics independently.
Correct Answer: B
Explanation: Patients with prosthetic heart valves are among those for whom
infective endocarditis prophylaxis may be indicated before procedures involving
gingival manipulation. Dental hygienists should verify recommendations and
coordinate with the supervising dentist and physician as appropriate.
Question 2
A patient reports frequent spontaneous gingival bleeding, petechiae, and prolonged
bleeding following minor cuts. Which condition should be suspected before
instrumentation?
A. Iron deficiency anemia
B. Hypertension
C. Possible platelet disorder
D. Hypothyroidism
Correct Answer: C
Explanation: Petechiae and spontaneous bleeding are characteristic findings
associated with platelet abnormalities, requiring further medical evaluation before
invasive procedures.
,Question 3
Following steam sterilization, which indicator provides the strongest evidence that
sterilization conditions were achieved?
A. Internal chemical indicator only
B. External indicator tape
C. Biological monitoring with spore testing
D. Sterilizer temperature gauge
Correct Answer: C
Explanation: Biological indicators using resistant bacterial spores remain the gold
standard for verifying sterilization effectiveness.
Question 4
A patient with uncontrolled diabetes presents with generalized Stage III periodontitis.
Which factor most significantly influences periodontal treatment outcomes?
A. Daily vitamin intake
B. Glycemic control
C. Eye examination history
D. Hand dominance
Correct Answer: B
Explanation: Poor glycemic control is strongly associated with increased
periodontal inflammation and impaired healing.
Question 5
Which radiographic error most commonly results from inadequate horizontal
angulation?
, A. Cone cut
B. Elongation
C. Overlapping contacts
D. Foreshortening
Correct Answer: C
Explanation: Incorrect horizontal angulation causes overlap of proximal surfaces,
limiting caries detection.
Question 6
A patient experiences dizziness, sweating, and pallor during treatment. Pulse is slow,
and blood pressure is decreased. What is the most likely emergency?
A. Hyperglycemia
B. Vasovagal syncope
C. Myocardial infarction
D. Stroke
Correct Answer: B
Explanation: Vasovagal syncope commonly presents with bradycardia, hypotension,
pallor, and diaphoresis.
Question 7
Which microorganism is most strongly associated with aggressive periodontal
destruction?
A. Streptococcus mutans
B. Lactobacillus acidophilus
C. Aggregatibacter actinomycetemcomitans
D. Candida albicans
