Which of the following image receptor sizes would necessitate that only two bitewing radiographs be exposed in an adult patient?
A) Size 0
B) Size 1
C) Size 2
D) Size 3
D
Explanation: A) Size 3 (extra long) radiographic film packets with preattached tabs are especially made for taking horizontal bitewing radiographs in adult patients. Phosphor plates used for indirect digital imaging are also available in size 3. The advantage of these image receptors is that only one image receptor needs to be exposed on each side of the arch to image both premolars and all molars on one image.
