MULTIPLE CHOICE
1. A diastema is a space between two teeth in the same arch. When this arises between the
maxillary central incisors, it is often due to 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.
RIGHT CHOICE✔✔ A
A space, or lack of contact area, between any two teeth in the same arch is known as a
diastema. When a diastema arises between the maxillary central incisors, it is often due to 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 found on the
a. soft palate
b. hard palate
c. alveolar ridge
d. oral pharynx
RIGHT CHOICE✔✔ B
Torus palatinus is excess bone growth and arises 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 arise on the soft
palate, alveolar ridge, or oral pharynx.

3. Contraction of which muscle lifts the tongue upward?
a. Mylohyoid
b. Palatopharyngeal
c. Palatoglossal
d. Levator glossal
RIGHT CHOICE✔✔ A
, Contraction of the mylohyoid muscle lifts 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.
RIGHT CHOICE✔✔ 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 these 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.
RIGHT CHOICE✔✔ D
The uvula is a downwardly projecting muscular tissue located at the midline of the most posterior
