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

Torus palatinus is excess bone growth and occurs in the midline of the hard

palate. Itmay grow to varying sizes and is generally only a problem when the
q q q q q q q q q q q q q q q
construction of amaxillary denture is necessary. In health, such bony protuberances, or
q q q q q q q q q q q q q
excess bonegrowths, do not occur on the soft palate, alveolar ridge, or oral

the palatoglossal muscle form the posterolateral borders of the oral cavity. There is

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