Exam 15: The Bitewing Examination

The presence of each of the following conditions may indicate using the bisecting technique instead of the paralleling technique EXCEPT one. Which one is the EXCEPTION?

The recommended vertical angulation for exposing a maxillary molar periapical radiograph using the bisecting technique is:

Careful attention to the steps of the bisecting technique can produce acceptable radiographs.

A longer 12-inch or 16-inch PID is better suited to the bisecting technique.

Using the bisecting technique, the image receptor is placed parallel to the long axes of the teeth.

The recommended vertical angulation for exposing a maxillary canine periapical radiograph using the bisecting technique is:

Even when the positioning and angulation steps are accurate and precise, the bisecting technique will produce some dimension distortion.

The bisecting technique is useful in patients who cannot tolerate parallel placement of the image receptor. The bisecting technique produces images with reduced image distortion.

Describe the error that results when excessive vertical angulation is used when taking periapical radiographs using the bisecting technique.

Which of these image receptor holders is designed for use with the bisecting technique?
