INTRODUCTION
This comprehensive examination is designed to rigorously assess the core
competencies required for the Florida Dental Hygiene Licensure Exam. It evaluates
foundational scientific knowledge, clinical reasoning, and the practical application
of the dental hygiene process of care. The exam includes multiple-choice and
scenario-based questions that test your ability to diagnose, plan, implement, and
evaluate patient care. You will be challenged on real-world clinical decision-
making, emergency preparedness, ethical considerations, and adherence to Florida-
specific regulatory standards. This assessment serves as a critical tool to measure
readiness for professional practice.
════════════════════════════════════
SECTION ONE: QUESTIONS 1–50
════════════════════════════════════
,1. Which of the following is the primary causative agent for dental caries?
A. Streptococcus mutans
B. Porphyromonas gingivalis
C. Lactobacillus acidophilus
D. Tannerella forsythia
🟢 Correct Answer: A. Streptococcus mutans
🔴 Explanation: Streptococcus mutans is the principal pathogen responsible for
initiating dental caries due to its ability to metabolize sucrose and produce
extracellular polysaccharides, facilitating adhesion to the tooth surface and acid
production.
2. The normal range for resting salivary pH is:
A. 5.5 – 6.0
B. 6.0 – 7.0
C. 7.0 – 7.5
D. 4.5 – 5.5
🟢 Correct Answer: B. 6.0 – 7.0
🔴 Explanation: The typical resting pH of saliva ranges from 6.0 to 7.0. A pH
below 5.5 is considered critical for enamel demineralization, leading to caries.
3. In the ADPIED process of care, which phase involves the identification of a
patient's health status and needs?
A. Planning
B. Evaluation
C. Assessment
D. Diagnosis
🟢 Correct Answer: C. Assessment
,🔴 Explanation: The Assessment phase is the initial step where the dental
hygienist collects comprehensive data, including patient history, clinical
examinations, and radiographs, to identify health status and needs.
4. Which of the following is a contraindication for the use of ultrasonic scalers?
A. Light, supragingival calculus deposits
B. Patients with pacemakers (non-shielded)
C. Moderate gingivitis
D. Presence of orthodontic brackets
🟢 Correct Answer: B. Patients with pacemakers (non-shielded)
🔴 Explanation: Non-shielded pacemakers are susceptible to electromagnetic
interference from ultrasonic scalers. This is a specific contraindication to prevent
potential cardiac complications.
5. Clinically, a localized, painless swelling on the gingiva that exhibits a
"basketball" or "cobblestone" appearance is most characteristic of:
A. Pyogenic granuloma
B. Fibroma
C. Peripheral ossifying fibroma
D. Gingival hyperplasia
🟢 Correct Answer: A. Pyogenic granuloma
🔴 Explanation: Pyogenic granuloma typically appears as a smooth or lobulated,
painless, red-to-purple exophytic mass. Its "basketball" or "cobblestone"
appearance and predilection for the gingiva are hallmark clinical features.
6. The recommended dosage of 2% lidocaine with 1:100,000 epinephrine for a
healthy adult is:
, A. 1.8 mg
B. 36 mg
C. 50 mg
D. 300 mg
🟢 Correct Answer: B. 36 mg
🔴 Explanation: The maximum recommended dose (MRD) for 2% lidocaine is 4.4
mg/kg (approximately 300 mg for a 70kg adult). A standard cartridge of 2%
lidocaine contains 36 mg (1.8 mL x 20 mg/mL), making 36 mg a safe and typical
dose for a dental procedure.
7. When interpreting a panoramic radiograph, the radiolucent structure located
anterior to the mental foramen is the:
A. Mandibular canal
B. Genial tubercles
C. Nutrient canals
D. Mental fossa
🟢 Correct Answer: D. Mental fossa
🔴 Explanation: The mental fossa is a radiolucent depression located anterior to
the mental foramen. It is a normal anatomical landmark and is often visible on
panoramic images.
8. A patient presents with an elevated serum glucose level of 310 mg/dL. Which
medical emergency is of immediate concern?
A. Hypoglycemia
B. Diabetic ketoacidosis (DKA)
C. Hyperglycemic hyperosmolar state
D. Insulin shock
