The size 3 image receptor has two advantages over a size 2 image receptor when exposing a bitewing radiograph

Question

Indicate whether the statement is true or false

Answer 1

FALSE
Explanation: When compared with the standard size 2 image receptor, the size 3 has two disadvantages. One is that most dental arches curve so that the horizontal angle required to clearly image the proximal surfaces of the premolars is not the same horizontal angle required to clearly image the proximal surfaces of the molars. There are two slightly divergent pathways of the posterior teeth. As the central rays pass through these divergent embrasures, it is not likely that all of the interproximal spaces will be imaged clearly without overlapping. The other disadvantage is that the long image receptor is narrower in the vertical dimension than size 2 and may reveal less of the periodontal crestal bone level.
