Section 1: Chapter 01 – Introduction to Preliminary Diagnosis of Oral
Lesions (12 questions)
Q1: A dental hygienist observes multiple small, yellowish papules on the buccal mucosa
bilaterally in an asymptomatic 45-year-old patient. The patient reports these have been
present for many years without change. Which of the following is the most likely
diagnosis?
A. Fordyce granules
B. Candidiasis
C. Lichen planus
D. Koplik spots [CORRECT]
Correct Answer: A
Rationale: Fordyce granules are ectopic sebaceous glands appearing as small yellowish
papules on the buccal mucosa and lips, representing a common variant of normal
anatomy that requires no treatment, as described in Ibsen & Phelan's Oral Pathology for
the Dental Hygienist 7th Edition.
Q2: During an intraoral examination, a dental hygienist notes a diffuse, grayish-white,
filmy appearance on the buccal mucosa bilaterally that disappears when the tissue is
stretched. The patient is asymptomatic. Which condition is most consistent with this
presentation?
A. Leukoplakia
B. Linea alba
C. Leukoedema [CORRECT]
D. Lichen planus
Correct Answer: C
,Rationale: Leukoedema presents as a diffuse, grayish-white, filmy appearance on the
buccal mucosa that characteristically disappears when the tissue is stretched,
distinguishing it from leukoplakia and other white lesions that remain visible upon
stretching.
Q3: A 52-year-old patient presents with a hard, bony protuberance along the midline of
the hard palate that has been present for 20 years. The lesion is covered by
normal-appearing mucosa and is asymptomatic. Which diagnostic method is most
appropriate for confirming this finding?
A. Incisional biopsy
B. Clinical examination and radiographic imaging [CORRECT]
C. Therapeutic diagnosis with antifungal medication
D. Excisional biopsy
Correct Answer: B
Rationale: A torus palatinus is a common exostosis of the hard palate best diagnosed
through clinical examination and radiographic imaging to confirm the bony nature;
biopsy is unnecessary unless the overlying tissue appears abnormal or the patient
requests removal.
Q4: A dental hygienist is performing a preliminary diagnosis on a patient with a raised,
exophytic lesion on the alveolar ridge. The lesion has a broad base attached directly to
the mucosal surface without a stalk. Which term best describes the base of this lesion?
A. Pedunculated
B. Sessile [CORRECT]
C. Papillary
D. Verrucous
Correct Answer: B
Rationale: A sessile base describes a lesion that is attached directly to the mucosal
surface by a broad base without a stalk or pedicle, distinguishing it from a pedunculated
lesion which is attached by a narrow stalk.
Q5: A 60-year-old patient presents with multiple tortuous, bluish-purple elevations on the
ventral surface of the tongue. The patient is asymptomatic and reports these have been
present for many years. Which of the following is the most appropriate classification for
these findings?
,A. Hemangiomas requiring surgical intervention
B. Lingual varicosities, a variant of normal [CORRECT]
C. Kaposi sarcoma lesions
D. Thrombosed blood vessels indicating systemic disease
Correct Answer: B
Rationale: Lingual varicosities are dilated, tortuous veins commonly found on the ventral
surface of the tongue in older adults, representing a benign age-related variant of
normal that requires no treatment.
Q6: A dental hygienist observes a white line on the buccal mucosa at the level of the
occlusal plane bilaterally. The patient reports no symptoms, and the line corresponds to
the area of occlusal contact. Which of the following best describes this finding?
A. Leukoplakia requiring biopsy
B. Linea alba, a frictional keratosis [CORRECT]
C. Lichen planus
D. Candidal infection
Correct Answer: B
Rationale: Linea alba is a horizontal white line on the buccal mucosa at the level of the
occlusal plane caused by frictional keratosis from the teeth; it is a benign finding
requiring no treatment and must be distinguished from potentially premalignant
leukoplakia.
Q7: A patient presents with a solitary red patch on the palate that has been present for
three weeks. The dental hygienist suspects a vascular lesion. Which diagnostic method
would be most appropriate to confirm whether this lesion blanches under pressure?
A. Radiographic imaging
B. Laboratory culture
C. Clinical examination using diascopy (pressure with glass slide) [CORRECT]
D. Excisional biopsy
Correct Answer: C
Rationale: Diascopy, the application of pressure with a glass slide to observe whether a
lesion blanches, is a simple clinical diagnostic technique used to differentiate vascular
lesions (which blanch) from nonvascular red lesions.
, Q8: During a preliminary diagnosis, a dental hygienist documents a lesion as "macule,
red, 5mm diameter, dorsal tongue, asymptomatic." Which of the following best
describes a macule?
A. A raised, solid lesion greater than 1cm
B. A flat, discolored spot less than 1cm in diameter [CORRECT]
C. A fluid-filled blister less than 1cm
D. A depressed lesion involving loss of tissue
Correct Answer: B
Rationale: A macule is defined as a flat, discolored spot on the skin or mucosa that is
less than 1cm in diameter, with no elevation or depression of the surface, distinguishing
it from papules, vesicles, and ulcers.
Q9: A 35-year-old patient presents with a well-circumscribed, elevated, solid lesion
measuring 8mm on the buccal mucosa. The dental hygienist correctly documents this
as which type of lesion?
A. Macule
B. Papule
C. Nodule [CORRECT]
D. Vesicle
Correct Answer: C
Rationale: A nodule is a solid, elevated lesion greater than 1cm (or in some
classifications, 5mm-1cm) that extends deeper into the connective tissue than a papule;
this lesion's size and solid, elevated nature best fit the description of a nodule.
Q10: A dental hygienist is evaluating a patient with a nonhealing ulcer on the lateral
tongue of three weeks' duration. The patient smokes and drinks alcohol daily. Which
diagnostic approach is most appropriate as the next step?
A. Reassess in two weeks
B. Prescribe antifungal medication as therapeutic diagnosis
C. Refer for incisional biopsy [CORRECT]
D. Order panoramic radiograph
Correct Answer: C
Rationale: A nonhealing ulcer in a high-risk patient (tobacco and alcohol use) on the
lateral tongue requires incisional biopsy to rule out squamous cell carcinoma, as any
oral lesion persisting beyond two weeks in a high-risk patient warrants tissue diagnosis
per NBDHE standards.
