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

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

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


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


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


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


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


or cutting, of the frenal tissue between teeth.

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


a. soft palate v


b. hard palate v


c. alveolar ridge v


d. oral pharynx v




ANS: B v


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


grow to varying sizes and is generally only a problem when the construction of a maxillary
v v v v v v v v v v v v v v v v


denture is necessary. In health, such bony protuberances, or excess bone growths, do not
v v v v v v v v v v v v v v


occur on the soft palate, alveolar ridge, or oral pharynx.

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


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


by the name of levator glossal.

4. The oral vestibule is partially bordered by the lips and cheeks. The oral cavity proper extends

vposteriorly to the soft palate. v v v v

v v v v v v v v v

d. Both statements are false. v v v




ANS: B v


The oral vestibule is the space or potential space that exists between the lips or cheeks and
v v v v v v v v v v v v v v v v


teeth. In an edentulous person, the vestibule would extend between the lips or cheeks and the
v v v v v v v v v v v v v v v v


alveolar ridges. The oral cavity proper is surrounded by teeth or alveolar ridges and extends
v v v v v v v v v v v v v v v


all the way back to the palatine tonsils. This includes the region from the floor of the mouth
v v v v v v v v v v v v v v v v v v


upward to the hard and soft palates.

ANS: D v


The uvula is a downwardly projecting muscular tissue located at the midline of the most
v v v v v v v v v v v v v v


posterior portion of the hard palate. It is NOT necessary for swallowing.

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


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


incisive.

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

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


structure, thus the different spelling. There are no papillae located on either the buccal mucosa
v v v v v v v v v v v v v v v


or the floor of the mouth.

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

EXCEPT one. Which one is the EXCEPTION?

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


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


when examining the oral cavity. Fovea palatinae are small depressions in mucosa on either
v v v v v v v v v v v v v v


side of the posterior nasal spine indicating the junction of the hard and soft palate. Tonsillar
v v v v v v v v v v v v v v v v


pillars are folds of tissue that partially surround the tonsils. The sublingual fold extends

the EXCEPTION?

ANS: D v


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


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


palatoglossal arch or fold. The tonsils lie between the anterior and posterior pillars.
v v v v v v v v v v v v v


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


greater palatine foramina are located in the posterior portions of the hard palate lingual to the
v v v v v v v v v v v v v v v v


second and third maxillary molars.
