Which imaging technique helps minimize distortion between the long axis of a tooth and the film in dental radiography?

The bisecting angle technique is designed to minimize distortion by aligning the film perpendicular to the long axis of the tooth. In this method, the angle bisected is between the long axis of the tooth and the film. This helps ensure that the resulting image maintains the natural shape of the tooth, offering a more accurate representation.

Using this technique, practitioners can achieve better angulation, which is crucial for avoiding elongation or foreshortening that might occur with other techniques. The bisecting angle method is particularly useful for teeth that are more challenging to position in relation to the film.

Other techniques, like the standard paralleling technique, while effective for reducing distortion by using specific positioning, often require more advanced equipment and patient compliance. Therefore, the bisecting angle technique remains a straightforward alternative that successfully addresses the issue of distortion in dental radiography.
