A space, or lack of contact area, between any two teeth in the same arch is called a diastema.
s s s s s s s s s s s s s s s s s s
When a diastema occurs between the maxillary central incisors, it is often theresult of
s s s s s s s s s s s s s s s
a pronounced labial frenum extending to the crest of the alveolar ridge andpossibly over
s s s s s s s s s s s s s s s
the ridge. This band of firm connective tissue causes the erupting incisorsto be
s s s s s s s s s s s s s s
pushed aside resulting in a diastema, or space. Correction of a diastema usually involves
s s s s s s s s s s s s s s
surgical removal, or cutting, of the frenal tissue between teeth.

Itmay grow to varying sizes and is generally only a problem when the construction

bonegrowths, do not occur on the soft palate, alveolar ridge, or oral pharynx.

ANS: B s
The oral vestibule is the space or potential space that exists between the lips or
s s s s s s s s s s s s s s
cheeks and teeth. In an edentulous person, the vestibule would extend between the lips
s s s s s s s s s s s s s s
or cheeksand the alveolar ridges. The oral cavity proper is surrounded by teeth or
s s s s s s s s s s s s s s s
alveolar ridges and extends all the way back to the palatine tonsils. This includes the
s s s s s s s s s s s s s s s
region from the floor of the mouth upward to the hard and soft palates.
