1. A diastema is a space between two teeth in the same arch. When this occurs between the maxillary central
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 d
maxillary central incisors, it is often the result of a pronounced labial frenum extending to the crest of t
possibly over the ridge. This band of firm connective tissue causes the erupting incisors to be pushed a

NAT: CDA: GC I.A.6. Identify basic oral anatomy and physiology, including but not limited to: oral cavity.

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 vary
only a problem when the construction of a maxillary denture is necessary. In health, such bony protube
growths, do not occur on the soft palate, alveolar ridge, or oral pharynx.

b. Palatopharyngeal
c. Palatoglossal
d. Levator glossal
