Introduction
This comprehensive examination is designed to assess the knowledge, clinical reasoning, and decision-
making skills essential for competent practice as a dental hygienist. It evaluates mastery across core
domains, including patient assessment, treatment planning, periodontology, pharmacology, radiology,
and professional ethics. The questions are structured to challenge theoretical understanding and the
practical application of concepts in real-world clinical scenarios. Emphasis is placed on critical
thinking, evidence-based care, and the ability to navigate complex patient cases, legal standards, and
safety protocols. This rigorous assessment reflects the depth and breadth of the current licensure
examination.
SECTION ONE: QUESTIONS 1 – 100
1. A 45-year-old patient presents with generalized erythematous gingiva, marked edema, and
spontaneous bleeding. The patient reports a history of type 2 diabetes mellitus with poor
glycemic control. Which of the following is the most likely primary contributing factor to this
patient's gingival condition?
A. Hormonal fluctuations
B. Local plaque biofilm
C. Systemic inflammatory response to diabetes
D. Xerostomia
🟢 Correct answer: C
,🔴 Explanation: The patient's history of poorly controlled diabetes is a primary systemic factor that
alters the host inflammatory response, making the gingival tissues more susceptible to breakdown
and severe inflammation, even in the presence of plaque biofilm.
2. During a clinical examination, you note a localized area of gingival recession on the facial
aspect of tooth #22. The gingival margin is located 3 mm apical to the CEJ, and the attached
gingiva is 1 mm wide. Which of the following is the most appropriate initial recommendation for
this patient?
A. Refer for a gingival graft immediately.
B. Instruct the patient on a modified Stillman brushing technique.
C. Debride the area to promote reattachment.
D. Prescribe a chlorhexidine gluconate mouthwash.
🟢 Correct answer: B
🔴 Explanation: The modified Stillman technique is indicated for areas of gingival recession as it
places the bristles at a 45-degree angle, directing them towards the root surface to stimulate the
gingiva and help prevent further recession without causing additional trauma.
3. When performing a full-mouth periodontal assessment, which of the following instruments is
most appropriate for accurately determining the presence of a furcation involvement on a
maxillary molar?
A. Williams periodontal probe
B. Naber's probe
C. Explorer
D. University of Michigan 'O' probe
🟢 Correct answer: B
🔴 Explanation: A Naber's probe is specifically designed with a curved, blunt tip to assess the
horizontal and vertical depth of furcation involvements on multi-rooted teeth.
4. A patient taking a calcium channel blocker for hypertension presents with severe, generalized
gingival enlargement. The overgrowth is fibrotic and pale pink. The dental hygienist should
recognize this as a potential side effect of the medication and recommend:
A. Discontinuation of the medication.
B. Consultation with the prescribing physician for a possible medication change.
C. An increase in the dosage of the current medication.
D. A 0.12% chlorhexidine rinse to reduce the overgrowth.
🟢 Correct answer: B
🔴 Explanation: Drug-induced gingival enlargement is a known side effect of calcium channel
blockers. The standard protocol is to consult with the patient's physician to discuss the possibility of
substituting the medication with a different class of antihypertensive.
5. An 8-year-old child presents with a mixed dentition. Which of the following is a normal
physiological characteristic of the gingiva in a child this age?
, A. Stippled, pale pink gingiva with a scalloped contour.
B. Pronounced, rolled margins with a bluish hue.
C. Flattened interdental papillae.
D. Gingival margins coronal to the CEJ of newly erupted teeth.
🟢 Correct answer: D
🔴 Explanation: In children with a mixed dentition, it is normal for the gingival margin to be located
coronally, or on the enamel, of newly erupted teeth. The gingiva often appears more erythematous
and edematous as the permanent teeth erupt.
6. A patient presents with an asymptomatic, solitary, pedunculated, soft tissue lesion on the
gingiva between teeth #8 and #9. The lesion is pink, rubbery, and measures approximately 1.5
cm in diameter. The patient reports it began after a piece of popcorn became lodged in the area.
The most likely diagnosis is:
A. Peripheral ossifying fibroma
B. Pyogenic granuloma
C. Gingival fibroma
D. Giant cell granuloma
🟢 Correct answer: B
🔴 Explanation: The clinical presentation of a pedunculated, erythematous or pink, rubbery lesion
that appears rapidly, often following trauma, is characteristic of a pyogenic granuloma.
7. Which of the following local anesthetic agents is most appropriate for a patient with a known
allergy to esters?
A. Lidocaine
B. Procaine
C. Tetracaine
D. Benzocaine
🟢 Correct answer: A
🔴 Explanation: Lidocaine is an amide local anesthetic. Patients with a known allergy to ester-type
local anesthetics can safely receive amide anesthetics. Procaine, tetracaine, and benzocaine are all
esters.
8. When exposing a panoramic radiograph, which of the following positioning errors will result
in the anterior teeth appearing "fat" and the posterior teeth appearing "thin"?
A. The patient's chin is too high.
B. The patient's chin is too low.
C. The patient's head is turned.
D. The patient's tongue is not on the palate.
🟢 Correct answer: B
🔴 Explanation: When the chin is positioned too low (Frankfort plane not parallel to the floor), the
image will show a "reverse smile" line, where the anterior teeth appear wider (fat) and the posterior
teeth appear narrower (thin) due to the angle of the x-ray beam.
