MULTIPLE CHOICE

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



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

ANS: A J



A space, or lack of contact area, between any two teeth in the same arch is called a diastema.
J J J J J J J J J J J J J J J J J J J



When a diastema occurs between the maxillary central incisors, it is often the result of a
J J J J J J J J J J J J J J J J



pronounced labial frenum extending to the crest of the alveolar ridge and possibly over the
J J J J J J J J J J J J J J J



ridge. This band of firm connective tissue causes the erupting incisors to be pushed aside
J J J J J J J J J J J J J J J



resulting in a diastema, or space. Correction of a diastema usually involves surgical removal, or
J J J J J J J J J J J J J J J



cutting, of the frenal tissue between teeth.

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



a. soft palate J



b. hard palate J



c. alveolar ridge J



d. oral pharynx J




ANS: B J



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



to varying sizes and is generally only a problem when the construction of a maxillary denture is
J J J J J J J J J J J J J J J J J



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



palate, alveolar ridge, or oral pharynx.

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



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

posteriorly to the soft palate. J J J J

ANS: B J



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



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



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



back to the palatine tonsils. This includes the region from the floor of the mouth upward to the
J J J J J J J J J J J J J J J J J J



hard and soft palates.

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

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

7. Each of the following structures can readily be viewed when examining the oral cavity

EXCEPT one. Which one is the EXCEPTION? J J J J J J



a. Fovea palatinae J



b. Tonsillar pillars J



c. Laryngeal pharynx J



d. Sublingual fold J




ANS: C J



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

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



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



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

EXCEPTION?
a. Incisive papilla J



b. Rugae
c. Greater palatine foramina J J



d. The anterior and posterior pillars J J J J




ANS: D J



The anterior and posterior pillars are located posterior to the soft palate. The posterior pillar is also
J J J J J J J J J J J J J J J J J



called the palatopharyngeal arch or fold. The anterior pillar is also called the palatoglossal arch
J J J J J J J J J J J J J J J



or fold. The tonsils lie between the anterior and posterior pillars.
J J J J J J J J J J



The incisive papilla and rugae are located on the anterior portion of the hard palate. The greater
J J J J J J J J J J J J J J J J J



palatine foramina are located in the posterior portions of the hard palate lingual to the second and
J J J J J J J J J J J J J J J J J



third maxillary molars.
