MULTIPLE CHOICE

 

1. You have been asked to take a single image on your patient to evaluate his maxilla and the mandible. Which of the following should you take?

a.	Four bite-wing images
b.	18-image periapical series
c.	21-image periapical series
d.	Panoramic

 

 

ANS:  D

The panoramic image allows the dental professional to view the largest area of the mandible and maxilla on a single image. Bite-wing images do not permit visualization of the apical area. An 18-image periapical series does not permit visualization of the entire maxilla and mandible. A 21-image periapical series does not permit visualization of the entire maxilla and mandible.

2. This bilateral landmark is located above the apices of the maxillary premolars and molars and appears radiolucent on the panoramic image.

a.	Maxillary sinus
b.	Maxilla
c.	Incisive foramen
d.	Infraorbital foramen

 

 

ANS:  A

The maxillary sinuses appear as paired radiolucent areas located superior to the apices of maxillary premolars and molars. The floor of the maxillary sinus is composed of dense cortical bone and appears as a radiopaque line. The maxilla forms the floor of the orbit of the eyes, the sides and floor of the nasal cavity, and the hard palate. The incisive foramen is a hole or opening in bone located at the midline of the anterior portion of the hard palate. The infraorbital foramen is a hole or opening in bone located inferior to the border of the orbit.
