MULTIPLE CHOICE

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
or space. Correction of a diastema usually involves surgical removal, or cutting, of the frenal tissue bet

2. Torus palatinus is seen on the

ANS: B
Torus palatinus is excess bone growth and occurs in the midline of the hard palate. It may grow to vary
