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.
ANSWER: 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
ANSWER: 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.
3. Contraction of which muscle raises the tongue upward?
a. Mylohyoid
b. Palatopharyngeal
c. Palatoglossal
d. Levator glossal
ANSWER: 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.
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.
ANSWER: 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.
ANSWER: 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.
