If periapical radiographs are available, there is no need to expose additional bitewing radiographs.

Question

Quizplus · Accepted Answer

Periapical radiographs are used to capture an image of the entire tooth, including the roots and surrounding bone, while bitewing radiographs are used to capture images of the crowns of adjacent teeth in one image. Therefore, if a dentist requires both a view of the root structure and the crowns of adjacent teeth, both kinds of radiographs may be necessary. Additionally, bitewing radiographs are useful for detecting interproximal decay, which may not be evident on periapical radiographs alone.
