MULTIPLE CHOICE
1. A diastema is a space between two teeth in the same arch. When this occurs between the
maxillary central incisors, it is often the result of a pronounced labial frenum.
a. Both statements are true.
b. The first statement is true; the second statement is false.
c. The first statement is false; the second statement is true.
d. Both statements are false.
ANS: A
A space, or lack of contact area, between any two teeth in the same arch is called a diastema.
When a diastema occurs between the maxillary central incisors, it is often the result of a
pronounced labial frenum extending to the crest of the alveolar ridge and possibly over the
ridge. This band of firm connective tissue causes the erupting incisors to be pushed aside
resulting in a diastema, or space. Correction of a diastema usually involves surgical removal,
or cutting, of the frenal tissue between teeth.

b. mandibular tori.
c. exostoses.
d. maxillary tuberosity.
ANS: C
Exostoses, small bony growths that occur on the buccal cortical plate on the mandible and the
maxillae, are seen in a large portion of the population. They are normally inconsequential
unless they become tender or a denture is needed. Exostoses occur more frequently on the
mandible than on the maxillae.
Torus palatinus are excess bony growths that commonly occur in the midline of the palate.
Mandibular tori are bony swellings that frequently occur on the lingual surface of the
mandible at the canine area. The maxillary tuberosity is a rounded bony protrusion in the area
of the third molar.

a. Mucogingival junction
b. Alveolar mucosa
c. Labial frenum
d. Gingiva
ANS: B
The alveolar mucosa, a thin layer of loosely attached and movable tissue, covers a highly
vascular area. The presence of blood vessels immediately under this relatively thin mucosa is
responsible for the general reddish color. By contrast, the mucogingival junction that divides
the attached gingiva from the alveolar mucosa appears more pink in color. The gingiva and
labial frenum also appear pink in color.

11. Although a patient presenting with painful areas throughout the oral cavity or a child
presenting with gingival bleeding in the presence of excellent oral hygiene should be
monitored carefully, referral to a dental specialist or physician is not indicated. A patient with
a red and painful tongue does warrant such a referral as does a patient with moderate plaque
on all teeth.
a. Both statements are true.
b. The first statement is true; the second statement is false.
c. The first statement is false, the second statement is true.
, Test Bank - Anatomy of Orofacial Structures: A Comprehensive Approach 9th Edition (Brand, 2024)
d. Both statements are false.
ANS: D
Of the four situations presented in this two-part question, only the patient with moderate
plaque on all teeth does NOT warrant referral to a specialist. This patient should receive
appropriate oral hygiene instructions, oral debridement, and be carefully monitored with short
re-care appointments. The remaining three oral conditions described in the question describe
conditions suggestive of systemic involvement and warrant further investigation, typically
referral to a dental specialist or physician. In particular, gingival bleeding in the presence of
excellent oral hygiene is a possible early sign of leukemia.

c. The first statement is false; the second statement is true.
d. Both statements are false.
ANS: C
Fordyce granules are misplaced sebaceous glands found in the oral cavity. These glands are
normally associated with hair follicles, which are normally located in the skin. The most
common locations for Fordyce granules are the lips, cheeks, and retromolar pads. Rugae are
hard transverse ridges of epithelial and connective tissue located in the anterior portion of the
hard palate.

14. Of the following structures, which is the MOST susceptible to trauma?
a. Hard palate
b. Buccal mucosa
c. Floor of the mouth
d. Dorsal surface of the tongue
e. Attached gingiva
ANS: C
Although any oral tissue may be traumatized, the tissue in the floor of the mouth is one of the
thinnest and thus very conducive to trauma. The hard palate and the attached gingiva have a
more protective, fibrous nature. The dorsal (top) tongue and the buccal mucosa also have
more protective features than does the mucosal lining on the floor of the mouth. Not listed as
a selection, the ventral (lower) surface of the tongue is quite vulnerable to trauma.

15. A generally healthy man in his forties is curious about “little raised yellow spots” on his
buccal mucosa. He has noticed them in the past but they do not seem to cause problems or
become larger, so has not previously asked about them. These areas are MOST likely
a. vallate papillae.
b. Kaposi’s spots.
c. Fordyce granules.
d. measles.
ANS: C
Fordyce granules are ectopic, or misplaced, sebaceous glands that occur on oral mucosal
surfaces. They appear as small raised yellowish or whitish spots. Although alarming to
patients, these formations are harmless. Vallate papillae, also called circumvallate papillae,
are the large V-shaped row of taste buds located on the posterior dorsum of the tongue.
Kaposi’s spots, associated with immunodeficiency, are red and painful. Measles can appear
anywhere on the body, including the oral cavity, and are red in color.

Fordyce granules are misplaced sebaceous glands that appear as very small yellowish granular
structures on oral mucosal surfaces in the oral cavity of 60% to 80% of the population.
Sebaceous glands normally occur in the skin; when they are present in the oral cavity they are
considered misplaced, or ectopic. Although Fordyce granules may be alarming to patients,
they are harmless. They most commonly occur in the mucosa of the lips, cheeks, retromolar
pads, and gingival tissues.

vascular area. The presence of blood vessels immediately under this relatively thin mucosa is
responsible for the general reddish color. By contrast, the mucogingival junction that divides
the attached gingiva from the alveolar mucosa appears more pink in color. The gingiva and
labial frenum also appear pink in color.

11. Although a patient presenting with painful areas throughout the oral cavity or a child
presenting with gingival bleeding in the presence of excellent oral hygiene should be
monitored carefully, referral to a dental specialist or physician is not indicated. A patient with
a red and painful tongue does warrant such a referral as does a patient with moderate plaque
on all teeth.

ANS: D
Of the four situations presented in this two-part question, only the patient with moderate
plaque on all teeth does NOT warrant referral to a specialist. This patient should receive
appropriate oral hygiene instructions, oral debridement, and be carefully monitored with short
re-care appointments. The remaining three oral conditions described in the question describe
conditions suggestive of systemic involvement and warrant further investigation, typically
referral to a dental specialist or physician. In particular, gingival bleeding in the presence of
excellent oral hygiene is a possible early sign of leukemia.

a. Sublingual caruncle
b. Sublingual salivary gland
c. Sublingual fold
d. Lingual tonsils
e. All of the above
ANS: A
The sublingual caruncle, a small elevation on each side of the base of the lingual frenum, is
the opening for the submandibular and sublingual salivary glands. Of the structures provided
in the question, it is located most closely to the lingual frenum. The sublingual fold extends
posteriorly from the sublingual caruncle. The lingual tonsils are located at the base of the
tongue.

Fordyce granules are misplaced sebaceous glands found in the oral cavity. These glands are
normally associated with hair follicles, which are normally located in the skin. The most
common locations for Fordyce granules are the lips, cheeks, and retromolar pads. Rugae are
hard transverse ridges of epithelial and connective tissue located in the anterior portion of the
hard palate.

14. Of the following structures, which is the MOST susceptible to trauma?
a. Hard palate
b. Buccal mucosa
c. Floor of the mouth
d. Dorsal surface of the tongue
e. Attached gingiva
ANS: C
Although any oral tissue may be traumatized, the tissue in the floor of the mouth is one of the
thinnest and thus very conducive to trauma. The hard palate and the attached gingiva have a
more protective, fibrous nature. The dorsal (top) tongue and the buccal mucosa also have
more protective features than does the mucosal lining on the floor of the mouth. Not listed as
a selection, the ventral (lower) surface of the tongue is quite vulnerable to trauma.

a. vallate papillae.
b. Kaposi’s spots.
c. Fordyce granules.
d. measles.
ANS: C
Fordyce granules are ectopic, or misplaced, sebaceous glands that occur on oral mucosal
surfaces. They appear as small raised yellowish or whitish spots. Although alarming to
patients, these formations are harmless. Vallate papillae, also called circumvallate papillae,
are the large V-shaped row of taste buds located on the posterior dorsum of the tongue.
Kaposi’s spots, associated with immunodeficiency, are red and painful. Measles can appear
anywhere on the body, including the oral cavity, and are red in color.

Fordyce granules are misplaced sebaceous glands that appear as very small yellowish granular
structures on oral mucosal surfaces in the oral cavity of 60% to 80% of the population.
Sebaceous glands normally occur in the skin; when they are present in the oral cavity they are
considered misplaced, or ectopic. Although Fordyce granules may be alarming to patients,
they are harmless. They most commonly occur in the mucosa of the lips, cheeks, retromolar
pads, and gingival tissues.

a. mucobuccal fold.
b. maxillary labial frenum.
c. mandibular labial frenum.
d. mucogingival junction.
ANS: B
At the midline of the upper lip, a fold of connective tissue known as the maxillary labial
frenum can be found. A corresponding structure, the mandibular labial frenum, is present at
the midline of the lower lip. The upper frenum is usually more pronounced than the lower.
Both structures, as well as additional less well-defined frena, serve to attach the lips to the
arch and contain only connective tissue. Structure “b” is the mandibular labial frenum.
Structure “c” is the mucogingival junction. Structure “d” is the mucobuccal fold.
