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.

2. Torus palatinus is seen on the
a. soft palate.
b. hard palate.
c. alveolar ridge.
d. oral pharynx.
ANS: B
Torus palatinus is excess bone growth and occurs in the midline of the hard palate. It may
grow to varying sizes and is generally only a problem when the construction of a maxillary
denture is necessary. In health, such bony protuberances, or excess bone growths, do not occur
on the soft palate, alveolar ridge, or oral pharynx.

OBJ: To define the terms vestibule, oral cavity proper, mucobuccal fold, frenum, alveolar mucosa,
gingiva, exostoses, torus palatinus, and torus mandibularis

muscular/skeletal system. TOP: BLOOM: Remembering
3. Contraction of which muscle raises the tongue upward?
a. Mylohyoid
b. Palatopharyngeal
c. Palatoglossal
d. Levator glossal
ANS: A
, Contraction of the mylohyoid muscle raises the tongue. The palatopharyngeal muscle and the
palatoglossal muscle form the posterolateral borders of the oral cavity. There is not a muscle
by the name of levator glossal.

that form them

4. The oral vestibule is partially bordered by the lips and cheeks. The oral cavity proper extends
posteriorly to the soft palate.
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: B
The oral vestibule is the space or potential space that exists between the lips or cheeks and
teeth. In an edentulous person, the vestibule would extend between the lips or cheeks and the
alveolar ridges. The oral cavity proper is surrounded by teeth or alveolar ridges and extends
all the way back to the palatine tonsils. This includes the region from the floor of the mouth
upward to the hard and soft palates.

5. Each of the following is true of the uvula EXCEPT one. Which one is the EXCEPTION?
a. It is located at the most posterior portion of the hard palate.
b. It is located at the midline.
c. It is a downwardly projecting muscle.
d. It is necessary for swallowing.
ANS: D
The uvula is a downwardly projecting muscular tissue located at the midline of the most
posterior portion of the hard palate. It is NOT necessary for swallowing.

6. The circumvallate papillae are located on the hard palate, buccal mucosa, and floor of the
mouth. The papillae found on the tongue are the filiform, fungiform, vallate, foliate, and
incisive.
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: D
