Brand/Isselhard: Anatomy of Orofacial Structures, 8th Edition

MULTIPLE CHOICE

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

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

a. Both statements are true.

b. The first statement is true; the second statement is false.

c. The first statement is false; the second statement is true.

d. Both statements are false.

ANS: A

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

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

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

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

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

or cutting, of the frenal tissue between teeth.

2. Torus palatinus is seen on the

a. soft palate

b. hard palate

c. alveolar ridge

d. oral pharynx

ANS: B

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

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

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

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

3. Contraction of which muscle raises the tongue upward?

a. Mylohyoid

b. Palatopharyngeal

c. Palatoglossal

d. Levator glossal

ANS: A

U S N T O

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

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

by the name of levator glossal.

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

posteriorly to the soft palate.

a. Both statements are true.

b. The first statement is true; the second statement is false.

c. The first statement is false; the second statement is true.

d. Both statements are false.

ANS: B

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

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

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

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

upward to the hard and soft palates.

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

b. It is located at the midline.

c. It is a downwardly projecting muscle.

d. It is necessary for swallowing.

ANS: D

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

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

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

incisive.

a. Both statements are true.

b. The first statement is true; the second statement is false.

c. The first statement is false; the second statement is true.

d. Both statements are false.

ANS: D

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

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?

a. Fovea palatinae

b. Tonsillar pillars

c. Laryngeal pharynx

d. Sublingual fold

ANS: C

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

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

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

backward on either side of thNe floRor Iof thGe mBo.utCh anMd is situated just superior to the

8. Each of the following structures is located within the hard palate EXCEPT one. Which one is

the EXCEPTION?

a. Incisive papilla

b. Rugae

c. Greater palatine foramina

d. The anterior and posterior pillars

ANS: D

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

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

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

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

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

second and third maxillary molars.

9. The small bony growths that commonly occur on the buccal cortical plate of the maxillae and

the mandible are called

a. torus palatinus

b. mandibular tori

c. exostoses

d. maxillary tuberosity

ANS: C

Exostoses, small bony growths that occur on the buccal cortical plate on the mandible and the

maxillae, are seen in a large portion of the population. They are normally inconsequential

unless they become tender or a denture is needed. Exostoses occur more frequently on the

mandible than on the maxillae.

Torus palatinus are excess bony growths that commonly occur in the midline of the palate.

Mandibular tori are bony swellings that frequently occur on the lingual surface of the

mandible at the canine area. The maxillary tuberosity is a rounded bony protrusion in the area

of the third molar.

10. Which structure is the MOST vascular in appearance?

a. Mucogingival junction

b. Alveolar mucosa

c. Labial frenum

d. Gingiva

ANS: B

The alveolar mucosa, a thin layer of loosely attached and movable tissue, covers a highly

vascular area. The presence of blood vessels immediately under this relatively thin mucosa is

responsible for the general reddish color. By contrast, the mucogingival junction that divides

the attached gingiva from the alveolar mucosa appears more pink in color. The gingiva and

labial frenum also appear pink in color.

11. Although a patient presenting with painful areas throughout the oral cavity or a child

presenting with gingival bleeding in the presence of excellent oral hygiene should be

monitored carefully, referral to a dental specialist or physician is not indicated. A patient with

a red and painful tongue does warrant such a referral as does a patient with moderate plaque

on all teeth.

a. Both statements are true.

b. The first statement is true; the second statement is false.

c. The first statement is false, the second statement is true.

d. Both statements are false.

ANS: D

Of the four situations presented in this two-part question, only the patient with moderate

plaque on all teeth does NOT warrant referral to a specialist. This patient should receive

appropriate oral hygiene instructions, oral debridement, and be carefully monitored with short

re-care appointments. The remaining three oral conditions described in the question describe

conditions suggestive of systemic involvement and warrant further investigation, typically

referral to a dental specialist or physician. In particular, gingival bleeding in the presence of

excellent oral hygiene is a possible early sign of leukemia.

12. Which structure is most closely located to the lingual frenum?

a. Sublingual caruncle

b. Sublingual salivary gland

c. Sublingual fold

d. Lingual tonsils

e. All of the above

ANS: A

The sublingual caruncle, a small elevation on each side of the base of the lingual frenum, is

the opening for the submandibular and sublingual salivary glands. Of the structures provided

in the question, it is located most closely to the lingual frenum. The sublingual fold extends

posteriorly from the sublingual caruncle. The lingual tonsils are located at the base of the

tongue.
