MULTIPLE CHOICE r




1. A diastema is a space between two teeth in the same arch. When this occurs between the
r r r r r r r r r r r r r r r r


maxillary central incisors, it is often the result of a pronounced labial frenum. a. Both
r r r r r r r r r r r r r r r


r statements are true. r r


b. Thefirst statement is true; the second statement is false.
r r r r r r r r r


c. Thefirst statement is false; the second statement is true.
r r r r r r r r r


d. Both statements are false. r r r




ANS: A r


A space, or lack of contact area, between anytwo teeth in the same arch is called a diastema. When
r r r r r r r r r r r r r r r r r r r


a diastema occurs between the maxillary central incisors, it is often the result of a pronounced
r r r r r r r r r r r r r r r r


labial frenum extending to the crest of the alveolar ridge and possibly over the ridge. This band
r r r r r r r r r r r r r r r r r


of firm connective tissue causes the erupting incisors to be pushed aside resulting in a diastema,
r r r r r r r r r r r r r r r r


or space. Correction of a diastema usuallyinvolves surgical removal, or cutting, of the frenal
r r r r r r r r r r r r r r r


tissue between teeth.

2. Torus palatinus is seen on the r r r r r


a. soft palate r


b. hard palate r


c. alveolar ridge r


d. oral pharynx r




ANS: B r


Torus palatinus is excess bone growth and occurs in the midline of the hard palate. It may grow
r r r r r r r r r r r r r r r r r


to varying sizes and is generallyonlya problem when the construction of a maxillary denture is
r r r r r r r r r r r r r r r r r


necessary. In health, such bony protuberances, or excess bone growths, do not occur on the
r r r r r r r r r r r r r r r


soft palate, alveolar ridge, or oral pharynx.

3. Contraction of which muscle raises the tongue upward? r r r r r r r


a. Mylohyoid

, b. Palatopharyngeal
c. Palatoglossal
d. Levator glossal r




ANS: A r


Contraction of the mylohyoid muscle raises the tongue. The palatopharyngeal muscle and the
r r r r r r r r r r r r


palatoglossal muscle form the posterolateral borders of the oral cavity. There is not a muscle by the
r r r r r r r r r r r r r r r r r


name of levator glossal.

4. Theoral vestibule is partiallybordered bythelips and cheeks. Theoral cavityproper

extends posteriorly to the soft palate. a. Both statements are true.

b. Thefirst statement is true; the second statement is false.
r r r r r r r r r


c. Thefirst statement is false; the second statement is true.
r r r r r r r r r


d. Both statements are false. r r r




ANS: B r


The oral vestibule is the space or potential space that exists between the lips or cheeks and teeth.
r r r r r r r r r r r r r r r r r


In an edentulous person, the vestibule would extend between the lips or cheeks and the alveolar
r r r r r r r r r r r r r r r r


ridges. The oral cavity proper is surrounded by teeth or alveolar ridges and extends all the way back
r r r r r r r r r r r r r r r r r r


to the palatine tonsils. This includes the region from the floor of the mouth upward to the hard
r r r r r r r r r r r r r r r r r r


and soft palates.

a. It is located at the most posterior portion of the hard palate.
r r r r r r r r r r r

6. The circumvallate papillae are located on the hard palate, buccal mucosa, and floor of the
r r r r r r r r r r r r r r


mouth. The papillae found on the tongue are the filiform, fungiform, vallate, foliate, and
r r r r r r r r r r r r r r


incisive.

a. Both statements are true. r r r

d. Both statements are false. r r r




ANS: D r


All papillae listed in both statements are located on the tongue with the exception of the incisive
r r r r r r r r r r r r r r r r


papilla, which is located on the hard palate. Note that the incisive papilla is a singular structure, thus
r r r r r r r r r r r r r r r r r r


the different spelling. There are no papillae located on either the buccal mucosa or the floor of the
r r r r r r r r r r r r r r r r r r


mouth.

7. Each of the following structures can readilybe viewed when examining the oral cavity
r r r r r r r r r r r r r


EXCEPT one. Which one is the EXCEPTION? a. Fovea palatinae

b. Tonsillarpillars r


c. Laryngeal pharynx r


d. Sublingual fold r




ANS: C r


The laryngeal pharynx is located below the oral pharynx and cannot be seen while examining the
r r r r r r r r r r r r r r r


oral cavity. The fovea palatinae, the tonsillar pillars, and the sublingual fold can be seen when
r r r r r r r r r r r r r r r r


examining the oral cavity. Fovea palatinae are small depressions in mucosa on either side of the
r r r r r r r r r r r r r r r r


posterior nasal spine indicating the junction of the hard and soft palate. Tonsillar pillars are folds
r r r r r r r r r r r r r r r r
