Question 5

Which of the following may be involved in the disruption of the vermilion zone and may make it hard to determine the exact location of its mucocutaneous junction between the lips and the surrounding skin?

A) Scar tissue
B) Hypercalcification
C) Cleft palate
D) Symmetry

Accepted Answer

Disruption of the vermilion zone may make it hard to determine the exact location of its mucocutaneous junction between the lips and the surrounding skin.These changes may be due to scar tissue from past traumatic incidents,developmental disturbances,or cellular changes in the tissue such as occur with solar damage.These changes may also represent a more serious condition such as cancer; however,this can be verified only with tissue biopsy and microscopic examination.If this change is part of a past history of a cleft lip,this also needs to be noted in the patient record because of its impact on dental care.

Accepted Answer

Farther laterally to the infraorbital region is the zygomatic region,which overlies the bony support for the cheek,the zygomatic arch.The zygomatic arch extends from just below the lateral margin of the eye toward the middle part of the external ear,which is located posteriorly.Inferior to the zygomatic arch and just anterior to the external ear is the temporomandibular joint.

Accepted Answer

The chin is the major feature of the mental region of the face.The infraorbital region of the face is located inferior to the orbital region and lateral to the nasal region.Farther laterally is the zygomatic region,which overlies the bony support for the cheek,the zygomatic arch.The oral region of the face has many structures within it,such as the lips and oral cavity.

Question 9

The _____ region of the face is composed of the soft tissue of the cheek.&#10;A) infraorbital&#10;B) orbital&#10;C) temporal&#10;D) buccal

Accepted Answer

The buccal region of the face is composed of the soft tissue of the cheek.The infraorbital region of the face is located inferior to the orbital region and lateral to the nasal region.In the orbital region of the face,the eyeball and all its supporting structures are contained in the orbit of the skull,the bony eye socket.The temporal region is on the lateral side of the head at the temple.

Question 10

What part of the mandible extends upward and backward from the body of the mandible on each side?&#10;A) Coronoid process&#10;B) Mandibular symphysis&#10;C) Ramus&#10;D) Coronoid notch

Accepted Answer

The bone underlying the mental region is the mandible,or lower jaw.On the lateral aspect of the mandible,the stout,flat plate of the ramus (plural,rami) extends upward and backward from the body of the mandible on each side.At the anterior border of the ramus is a thin,sharp margin that terminates in the coronoid process.The midline of the mandible is marked by the mandibular symphysis.The main part of the anterior border of the ramus forms a concave forward curve,the coronoid notch.

Question 11
