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

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




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




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




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




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




cutting, of the frenal tissue between teeth.

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




a. soft palate ix




b. hard palate ix




c. alveolar ridge ix




d. oral pharynx ix




ANS: B i x




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




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




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




palate, alveolar ridge, or oral pharynx.

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




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

posteriorly to the soft palate.

ANS: B i x




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




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




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




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




hard and soft palates.

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
ix ix ix ix ix ix ix ix ix ix ix ix ix ix

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 structure,
ix ix ix ix ix ix ix ix ix ix ix ix ix ix ix ix ix




thus the different spelling. There are no papillae located on either the buccal mucosa or the floor
ix ix ix ix ix ix ix ix ix ix ix ix ix ix ix ix ix




of the mouth.

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




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




a. Fovea palatinae ix




b. Tonsillar pillars ix




c. Laryngeal pharynx ix




d. Sublingual fold ix




ANS: C i x




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




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




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




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




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

backward on either side of t hNe floRor I t hGe mBo.

a. Incisive papilla ix

c. Greater palatine foramina ix ix




d. The anterior and posterior pillars ix ix ix ix




ANS: D i x




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




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




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




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




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




third maxillary molars.
