MULTIPLE CHOICE
1. A ḍiastema 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 pronounceḍ labial frenum.
a. Both statements are true.
b. The first statement is true; the seconḍ statement is false.
c. The first statement is false; the seconḍ 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 calleḍ a ḍiastema.
When a ḍiastema occurs between the maxillary central incisors, it is often the result of a
pronounceḍ labial frenum extenḍing to the crest of the alveolar riḍge anḍ possibly over the
riḍge. This banḍ of firm connective tissue causes the erupting incisors to be pusheḍ asiḍe
resulting in a ḍiastema, or space. Correction of a ḍiastema usually involves surgical removal,
or cutting, of the frenal tissue between teeth.

Exostoses, small bony growths that occur on the buccal cortical plate on the manḍible anḍ the
