benefits, and alternatives to a medical treatment or procedure, allowing patients to make informed
decisions.However, challenges arise when patients are not fully capable of making informed decisions (e.g., due
to age, mental illness, or language barriers). In such cases, ethical dilemmas can arise regarding whether a third
party (e.g., a parent or guardian) should make the decision on the patient’s behalf, and whether the legal

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.
ANSWER: 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
ANSWER: 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.

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

ANSWER: 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.
