In a standard bitewing sequence, how many radiographs are typically taken?

In a standard bitewing sequence, the typical number of radiographs taken is four. This sequence is designed to effectively capture the interproximal areas of the posterior teeth (premolars and molars), as these regions are prone to caries and other dental issues.

The reason four radiographs are standard is that two images are typically taken for each side of the mouth—one for the premolars and one for the molars on each side. This allows the dentist to see both the upper and lower teeth effectively, providing a comprehensive view of the dental structures and any potential problems, while adhering to safety protocols and minimizing radiation exposure to the patient.

Taking fewer than four images might not sufficiently capture all necessary details, whereas taking more could lead to unnecessary exposure for the patient without providing additional diagnostic value.
