MULTIPLE CHOICE
| 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.

| 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.
